Background work & concurrency (using Schedulers)\n\nA common requirement is to offload lengthy heavy I/O intensive operations to a background thread (non-UI thread) and feed the results back to the UI/main thread, on completion. This is a demo of how long-running operations can be offloaded to a background thread. After the operation is done, we resume back on the main thread. All using RxJava! Think of this as a replacement to AsyncTasks.\n\nThe long operation is simulated by a blocking Thread.sleep call (since this is done in a background thread, our UI is never interrupted).\n\nTo really see this example shine. Hit the button multiple times and see how the button click (which is a UI operation) is never blocked because the long operation only runs in the background.\n\n### 2. Accumulate calls (using buffer)\n\nThis is a demo of how events can be accumulated using the \"buffer\" operation.\n\nA button is provided and we accumulate the number of clicks on that button, over a span of time and then spit out the final results.\n\nIf you hit the button once, you'll get a message saying the button was hit once. If you hit it 5 times continuously within a span of 2 seconds, then you get a single log, saying you hit that button 5 times (vs 5 individual logs saying \"Button hit once\").\n\nNote:\n\nIf you're looking for a more foolproof solution that accumulates \"continuous\" taps vs just the number of taps within a time span, look at the [EventBus Demo](https://github.com/kaushikgopal/Android-RxJava/blob/master/app/src/main/java/com/morihacky/android/rxjava/rxbus/RxBusDemo_Bottom3Fragment.java) where a combo of the `publish` and `buffer` operators is used. For a more detailed explanation, you can also have a look at this [blog post](https://kau.sh/blog/debouncedbuffer-with-rxjava/).\n\n### 3. Instant/Auto searching text listeners (using Subjects & debounce)\n\nThis is a demo of how events can be swallowed in a way that only the last one is respected. A typical example of this is instant search result boxes. As you type the word \"Bruce Lee\", you don't want to execute searches for B, Br, Bru, Bruce, Bruce, Bruce L ... etc. But rather intelligently wait for a couple of moments, make sure the user has finished typing the whole word, and then shoot out a single call for \"Bruce Lee\".\n\nAs you type in the input box, it will not shoot out log messages at every single input character change, but rather only pick the lastly emitted event (i.e. input) and log that.\n\nThis is the debounce/throttleWithTimeout method in RxJava.\n\n### 4. Networking with Retrofit & RxJava (using zip, flatmap)\n\n[Retrofit from Square](http://square.github.io/retrofit/) is an amazing library that helps with easy networking (even if you haven't made the jump to RxJava just yet, you really should check it out). It works even better with RxJava and these are examples hitting the GitHub API, taken straight up from the android demigod-developer Jake Wharton's talk at Netflix. You can [watch the talk](https://www.youtube.com/watch?v=aEuNBk1b5OE#t=2480) at this link. Incidentally, my motivation to use RxJava was from attending this talk at Netflix.\n\n(Note: you're most likely to hit the GitHub API quota pretty fast so send in an OAuth-token as a parameter if you want to keep running these examples often).\n\n### 5. Two-way data binding for TextViews (using PublishSubject)\n\nAuto-updating views are a pretty cool thing. If you've dealt with Angular JS before, they have a pretty nifty concept called \"two-way data binding\", so when an HTML element is bound to a model/entity object, it constantly \"listens\" to changes on that entity and auto-updates its state based on the model. Using the technique in this example, you could potentially use a pattern like the [Presentation View Model pattern](http://martinfowler.com/eaaDev/PresentationModel.html) with great ease.\n\nWhile the example here is pretty rudimentary, the technique used to achieve the double binding using a `Publish Subject` is much more interesting.\n\n### 6. Simple and Advanced polling (using interval and repeatWhen)\n\nThis is an example of polling using RxJava Schedulers. This is useful in cases, where you want to constantly poll a server and possibly get new data. The network call is \"simulated\" so it forces a delay before return a resultant string.\n\nThere are two variants for this:\n\n1. Simple Polling: say when you want to execute a certain task every 5 seconds\n2. Increasing Delayed Polling: say when you want to execute a task first in 1 second, then in 2 seconds, then 3 and so on.\n\nThe second example is basically a variant of [Exponential Backoff](https://github.com/kaushikgopal/RxJava-Android-Samples#exponential-backoff).\n\nInstead of using a RetryWithDelay, we use a RepeatWithDelay here. To understand the difference between Retry(When) and Repeat(When) I wouuld suggest Dan's [fantastic post on the subject](http://blog.danlew.net/2016/01/25/rxjavas-repeatwhen-and-retrywhen-explained/).\n\nAn alternative approach to delayed polling without the use of `repeatWhen` would be using chained nested delay observables. See [startExecutingWithExponentialBackoffDelay in the ExponentialBackOffFragment example](https://github.com/kaushikgopal/RxJava-Android-Samples/blob/master/app/src/main/java/com/morihacky/android/rxjava/fragments/ExponentialBackoffFragment.java#L111).\n\n### 7. Simple and Advanced exponential backoff (using delay and retryWhen)\n\n[Exponential backoff](https://en.wikipedia.org/wiki/Exponential_backoff) is a strategy where based on feedback from a certain output, we alter the rate of a process (usually reducing the number of retries or increasing the wait time before retrying or re-executing a certain process).\n\nThe concept makes more sense with examples. RxJava makes it (relatively) simple to implement such a strategy. My thanks to [Mike](https://twitter.com/m_evans10) for suggesting the idea.\n\n#### Retry (if error) with exponential backoff\n\nSay you have a network failure. A sensible strategy would be to NOT keep retrying your network call every 1 second. It would be smart instead (nay... elegant!) to retry with increasing delays. So you try at second 1 to execute the network call, no dice? try after 10 seconds... negatory? try after 20 seconds, no cookie? try after 1 minute. If this thing is still failing, you got to give up on the network yo!\n\nWe simulate this behaviour using RxJava with the [`retryWhen` operator](http://reactivex.io/documentation/operators/retry.html).\n\n`RetryWithDelay` code snippet courtesy:\n\n* http://stackoverflow.com/a/25292833/159825\n* Another excellent implementation via @[sddamico](https://github.com/sddamico) : https://gist.github.com/sddamico/c45d7cdabc41e663bea1\n* This one includes support for jittering, by @[leandrofavarin](https://github.com/leandrofavarin) : http://leandrofavarin.com/exponential-backoff-rxjava-operator-with-jitter\n\nAlso look at the [Polling example](https://github.com/kaushikgopal/RxJava-Android-Samples#polling-with-schedulers) where we use a very similar Exponential backoff mechanism.\n\n#### \"Repeat\" with exponential backoff\n\nAnother variant of the exponential backoff strategy is to execute an operation for a given number of times but with delayed intervals. So you execute a certain operation 1 second from now, then you execute it again 10 seconds from now, then you execute the operation 20 seconds from now. After a grand total of 3 times you stop executing.\n\nSimulating this behavior is actually way more simpler than the prevoius retry mechanism. You can use a variant of the `delay` operator to achieve this.\n\n\n### 8. Form validation (using [`.combineLatest`](http://reactivex.io/documentation/operators/combinelatest.html))\n\nThanks to Dan Lew for giving me this idea in the [fragmented podcast - episode #4](http://fragmentedpodcast.com/episodes/4/) (around the 4:30 mark).\n\n`.combineLatest` allows you to monitor the state of multiple observables at once compactly at a single location. The example demonstrated shows how you can use `.combineLatest` to validate a basic form. There are 3 primary inputs for this form to be considered \"valid\" (an email, a password and a number). The form will turn valid (the text below turns blue :P) once all the inputs are valid. If they are not, an error is shown against the invalid inputs.\n\nWe have 3 independent observables that track the text/input changes for each of the form fields (RxAndroid's `WidgetObservable` comes in handy to monitor the text changes). After an event change is noticed from **all** 3 inputs, the result is \"combined\" and the form is evaluated for validity.\n\nNote that the `Func3` function that checks for validity, kicks in only after ALL 3 inputs have received a text change event.\n\nThe value of this technique becomes more apparent when you have more number of input fields in a form. Handling it otherwise with a bunch of booleans makes the code cluttered and kind of difficult to follow. But using `.combineLatest` all that logic is concentrated in a nice compact block of code (I still use booleans but that was to make the example more readable).\n\n\n### 9. Pseudo caching : retrieve data first from a cache, then a network call (using concat, concatEager, merge or publish)\n\nWe have two source Observables: a disk (fast) cache and a network (fresh) call. Typically the disk Observable is much faster than the network Observable. But in order to demonstrate the working, we've also used a fake \"slower\" disk cache just to see how the operators behave.\n\nThis is demonstrated using 4 techniques:\n\n1. [`.concat`](http://reactivex.io/documentation/operators/concat.html)\n2. [`.concatEager`](http://reactivex.io/RxJava/javadoc/rx/Observable.html#concatEager(java.lang.Iterable))\n3. [`.merge`](http://reactivex.io/documentation/operators/merge.html)\n4. [`.publish`](http://reactivex.io/RxJava/javadoc/rx/Observable.html#publish(rx.functions.Func1)) selector + merge + takeUntil\n\nThe 4th technique is probably what you want to use eventually but it's interesting to go through the progression of techniques, to understand why.\n\n`concat` is great. It retrieves information from the first Observable (disk cache in our case) and then the subsequent network Observable. Since the disk cache is presumably faster, all appears well and the disk cache is loaded up fast, and once the network call finishes we swap out the \"fresh\" results.\n\nThe problem with `concat` is that the subsequent observable doesn't even start until the first Observable completes. That can be a problem. We want all observables to start simultaneously but produce the results in a way we expect. Thankfully RxJava introduced `concatEager` which does exactly that. It starts both observables but buffers the result from the latter one until the former Observable finishes. This is a completely viable option.\n\nSometimes though, you just want to start showing the results immediately. Assuming the first observable (for some strange reason) takes really long to run through all its items, even if the first few items from the second observable have come down the wire it will forcibly be queued. You don't necessarily want to \"wait\" on any Observable. In these situations, we could use the `merge` operator. It interleaves items as they are emitted. This works great and starts to spit out the results as soon as they're shown.\n\nSimilar to the `concat` operator, if your first Observable is always faster than the second Observable you won't run into any problems. However the problem with `merge` is: if for some strange reason an item is emitted by the cache or slower observable *after* the newer/fresher observable, it will overwrite the newer content. Click the \"MERGE (SLOWER DISK)\" button in the example to see this problem in action. @JakeWharton and @swankjesse contributions go to 0! In the real world this could be bad, as it would mean the fresh data would get overridden by stale disk data.\n\nTo solve this problem you can use merge in combination with the super nifty `publish` operator which takes in a \"selector\". I wrote about this usage in a [blog post](https://kau.sh/blog/rxjava-tip-for-the-day-share-publish-refcount-and-all-that-jazz/) but I have [Jedi JW](https://twitter.com/JakeWharton/status/786363146990649345) to thank for reminding of this technique. We `publish` the network observable and provide it a selector which starts emitting from the disk cache, up until the point that the network observable starts emitting. Once the network observable starts emitting, it ignores all results from the disk observable. This is perfect and handles any problems we might have.\n\nPreviously, I was using the `merge` operator but overcoming the problem of results being overwritten by monitoring the \"resultAge\". See the old `PseudoCacheMergeFragment` example if you're curious to see this old implementation.\n\n### 10. Simple timing demos (using timer, interval and delay)\n\nThis is a super simple and straightforward example which shows you how to use RxJava's `timer`, `interval` and `delay` operators to handle a bunch of cases where you want to run a task at specific intervals. Basically say NO to Android `TimerTask`s.\n\nCases demonstrated here:\n\n1. run a single task after a delay of 2s, then complete\n2. run a task constantly every 1s (there's a delay of 1s before the first task fires off)\n3. run a task constantly every 1s (same as above but there's no delay before the first task fires off)\n4. run a task constantly every 3s, but after running it 5 times, terminate automatically\n5. run a task A, pause for sometime, then execute Task B, then terminate\n\n### 11. RxBus : event bus using RxJava (using RxRelay (never terminating Subjects) and debouncedBuffer)\n\nThere are accompanying blog posts that do a much better job of explaining the details on this demo:\n\n1. [Implementing an event bus with RxJava](https://kau.sh/blog/implementing-an-event-bus-with-rxjava-rxbus/)\n2. [DebouncedBuffer used for the fancier variant of the demo](https://kau.sh/blog/debouncedbuffer-with-rxjava/)\n3. [share/publish/refcount](https://kau.sh/blog/rxjava-tip-for-the-day-share-publish-refcount-and-all-that-jazz/)\n\n### 12. Persist data on Activity rotations (using Subjects and retained Fragments)\n\nA common question that's asked when using RxJava in Android is, \"how do i resume the work of an observable if a configuration change occurs (activity rotation, language locale change etc.)?\".\n\nThis example shows you one strategy viz. using retained Fragments. I started using retained fragments as \"worker fragments\" after reading this [fantastic post by Alex Lockwood](http://www.androiddesignpatterns.com/2013/04/retaining-objects-across-config-changes.html) quite sometime back.\n\nHit the start button and rotate the screen to your heart's content; you'll see the observable continue from where it left off.\n\n*There are certain quirks about the \"hotness\" of the source observable used in this example. Check [my blog post](https://kau.sh/blog/a-note-about-the-warmth-share-operator/) out where I explain the specifics.*\n\nI have since rewritten this example using an alternative approach. While the [`ConnectedObservable` approach worked](https://github.com/kaushikgopal/RxJava-Android-Samples/blob/master/app/src/main/java/com/morihacky/android/rxjava/fragments/RotationPersist1WorkerFragment.java#L20) it enters the lands of \"multicasting\" which can be tricky (thread-safety, .refcount etc.). Subjects on the other hand are far more simple. You can see it rewritten [using a `Subject` here](https://github.com/kaushikgopal/RxJava-Android-Samples/blob/master/app/src/main/java/com/morihacky/android/rxjava/fragments/RotationPersist2WorkerFragment.java#L22).\n\nI wrote [another blog post](https://tech.instacart.com/how-to-think-about-subjects-part-1/) on how to think about Subjects where I go into some specifics.\n\n\n### 13. Networking with Volley\n\n[Volley](http://developer.android.com/training/volley/index.html) is another networking library introduced by [Google at IO '13](https://www.youtube.com/watch?v=yhv8l9F44qo). A kind citizen of github contributed this example so we know how to integrate Volley with RxJava.\n\n### 14. Pagination with Rx (using Subjects)\n\nI leverage the simple use of a Subject here. Honestly, if you don't have your items coming down via an `Observable` already (like through Retrofit or a network request), there's no good reason to use Rx and complicate things.\n\nThis example basically sends the page number to a Subject, and the subject handles adding the items. Notice the use of `concatMap` and the return of an `Observable` from `_itemsFromNetworkCall`.\n\nFor kicks, I've also included a `PaginationAutoFragment` example, this \"auto-paginates\" without us requiring to hit a button. It should be simple to follow if you got how the previous example works.\n\nHere are some other fancy implementations (while i enjoyed reading them, i didn't land up using them for my real world app cause personally i don't think it's necessary):\n\n* [Matthias example of an Rx based pager](https://gist.github.com/mttkay/24881a0ce986f6ec4b4d)\n* [Eugene's very comprehensive Pagination sample](https://github.com/matzuk/PaginationSample)\n* [Recursive Paging example](http://stackoverflow.com/questions/28047272/handle-paging-with-rxjava)\n\n### 15. Orchestrating Observable: make parallel network calls, then combine the result into a single data point (using flatmap & zip)\n\nThe below ascii diagram expresses the intention of our next example with panache. f1,f2,f3,f4,f5 are essentially network calls that when made, give back a result that's needed for a future calculation.\n\n\n (flatmap)\n f1 ___________________ f3 _______\n (flatmap) | (zip)\n f2 ___________________ f4 _______| ___________ final output\n \\ |\n \\____________ f5 _______|\n\nThe code for this example has already been written by one Mr.skehlet in the interwebs. Head over to [the gist](https://gist.github.com/skehlet/9418379) for the code. It's written in pure Java (6) so it's pretty comprehensible if you've understood the previous examples. I'll flush it out here again when time permits or I've run out of other compelling examples.\n\n### 16. Simple Timeout example (using timeout)\n\nThis is a simple example demonstrating the use of the `.timeout` operator. Button 1 will complete the task before the timeout constraint, while Button 2 will force a timeout error.\n\nNotice how we can provide a custom Observable that indicates how to react under a timeout Exception.\n\n### 17. Setup and teardown resources (using `using`)\n\nThe [operator `using`](http://reactivex.io/documentation/operators/using.html) is relatively less known and notoriously hard to Google. It's a beautiful API that helps to setup a (costly) resource, use it and then dispose off in a clean way.\n\nThe nice thing about this operator is that it provides a mechansim to use potentially costly resources in a tightly scoped manner. using -> setup, use and dispose. Think DB connections (like Realm instances), socket connections, thread locks etc.\n\n### 18. Multicast Playground\n\nMulticasting in Rx is like a dark art. Not too many folks know how to pull it off without concern. This example condiers two subscribers (in the forms of buttons) and allows you to add/remove subscribers at different points of time and see how the different operators behave under those circumstances.\n\nThe source observale is a timer (`interval`) observable and the reason this was chosen was to intentionally pick a non-terminating observable, so you can test/confirm if your multicast experiment will leak.\n\n_I also gave a talk about [Multicasting in detail at 360|Andev](https://speakerdeck.com/kaushikgopal/rx-by-example-volume-3-the-multicast-edition). If you have the inclination and time, I highly suggest watching that talk first (specifically the Multicast operator permutation segment) and then messing around with the example here._\n\n## Rx 2.x\n\nAll the examples here have been migrated to use RxJava 2.X.\n\n* Have a look at [PR #83 to see the diff of changes between RxJava 1 and 2](https://github.com/kaushikgopal/RxJava-Android-Samples/pull/83/files)\n* [What's different in Rx 2.x](https://github.com/ReactiveX/RxJava/wiki/What's-different-in-2.0)\n\nWe use [David Karnok's Interop library](https://github.com/akarnokd/RxJava2Interop) in some cases as certain libraries like RxBindings, RxRelays, RxJava-Math etc. have not been ported yet to 2.x.\n\n## Contributing:\n\nI try to ensure the examples are not overly contrived but reflect a real-world usecase. If you have similar useful examples demonstrating the use of RxJava, feel free to send in a pull request.\n\nI'm wrapping my head around RxJava too so if you feel there's a better way of doing one of the examples mentioned above, open up an issue explaining how. Even better, send a pull request.\n\n\n## Sponsorship (Memory Management/Profiling)\n\nRx threading is messy business. To help, this project uses YourKit tools for analysis.\n\n![Yourkit](https://www.yourkit.com/images/yklogo.png)\n\n\nYourKit supports open source projects with innovative and intelligent tools\nfor monitoring and profiling Java applications.

Settings\n \n\n bg work (schedulers & concurrency)\n accumulate calls (buffer)\n search text listener(debounce)\n Timeout long running jobs\n Retrofit + RxJava\n Double binding (PublishSubject)\n Polling with RxJava\n Event Bus with RxJava\n Form Validation with CombineLatest\n Pseudo cache using concat\n Variations of timing/intervals/delays\n Exponential backoff\n Rotation persist\n Volley request demo\n Paging example\n MOAR\n Network Detector (Subject)\n Setup & teardown resources (using)\n MultiConnect operator playground\n\n This is a demo of how you can do a list pagination with Rx. We page 10 items at a time and there are 55 items altogether\n This is a Volley request demo\n This is a demo of how long running operations can be offloaded to a background thread. After the operation is done, we resume back on the main thread. All using RxJava! \\n\\n To really see this shine. Hit the button multiple times and see how the button click which is a ui operation is never blocked because the long operation only runs in the background\n This is a demo of how events can be accumulated using the \"buffer\" operation. Tap the button below repetitively and you will notice in the logs that button taps are collected over a span of 2s and printed below.\n As you type in the input box, it will not shoot out log messages at every single input character change, but rather only pick the last one.\n This is a demo of terminating events, that take too long to process. Events in this demo should timeout in 3 seconds. Button 1 is an event that takes 2s to process, and Button 2 is a n event that takes 5s to process. Hit Button 2, and see in the logs that it\\'s been cancelled, while this is not the case for Button 1.\n Retrofit from Square is a super easy networking helper library. It works really well with RxJava and these are examples taken from Jake Wharton\\'s talk at Netflix (see README). Really the only interesting bits here are in the code and logs.\n This shows how you can replace an AsyncTask with RxJava. The interesting parts are in the code.\n Watch how the result gloriously auto-updates sed on your changing inputs. Using a technique like this, you could achieve the two-way binding in Angular Js, or more efficiently use a pattern like the Presentation View Model.\n Demo polling or making a call repeatedly with RxJava.\\n\\nSimple polling: Notice in the logs how a (simulated) network call is repeatedly made in the background.\n These two examples demonstrate retrying and executing with a delay using an exponential backoff strategy.\n Tap on the below button and RxBus will listen to the events\n Monitor the state of multiple observables with the combineLatest operator. Only after all the 3 inputs contain valid entries will the submit button light up\n BTN 1: run single task once (after 2s complete)\\nBTN 2: run task every 1s (start delay of 1s) toggle \\nBTN 3: run task every 1s (start immediately) toggle \\nBTN 4: run task 5 times every 3s (then complete) \\nBTN 5: run task A, pause for sometime, then proceed with Task B\n This is an example of starting an Observable and using the result across rotations. There are many ways to do this, we use ViewModels from architecture components\n This is a demo of how to use Subjects to detect Network connectivity\\nToggle your Wifi/Network on or off and notice the logs\n This is a demo of the somewhat unknown operator \"using\".\\n\\nYou typically use it for managing setup/teardown of resources. Classic cases are DB connections (like Realm), sockets, locks etc.\\n\\nTap the button and look at the logcat. Particularly notice how the Realm instance is self-contained. That is, it is auto-disposed right after use.\n RefCount starts the upstream right away and gets disposed off, when all subscribers stop. Hit S1, Hit S2, Hit S1, Hit S2. Hit S1/S2 now and notice the stream starts all over.\n AutoConnect(2) waits for a min. subscriber count, before starting the upstream. Hit S1 (notice events don\\'t start), Hit S2 (notice events now start), Hit S1 (notice that unsubscribing doesn\\'t affect upstream), Hit S2, wait for sometime and hit S1 again (notice source stream doesn\\'t restart)\n Replay caches the last item. Hit S1, Hit S2, event starts, Hit S2, wait a bit, Hit S2 again (notice it starts with the last item that S1 saw - courtesy Replay). Hit S2, Hit S1, wait a bit. Hit S1 again (notice event upstream continues and doesn\\'t restart)\n Replay caches the last item. Hit S1, wait a bit, then hit S2 (notice S2 starts immediately with last item that S1 saw), Hit S2, Hit S1. Hit S1/S2 again (notice the stream restarts all over. Interestingly cached last item also removed when both subscribers released)\n Courtesy: new #AndroidDev on the block - JakeWharton. exactly like replay(1).refCount(), but caches the last item even when upstream has been disposed off/released. Hit S1, Hit S2, Hit S1, Hit S2 (notice observable is disposed). Hit S1/S2 again (notice we start with last item emitted)\n\n Concat merges the results sequentially. But notice that the latter subscription starts only AFTER the first one completes. Some unnecessary waiting there.\n Concat eager is cooler. Both subscriptions start at the same time (parallely) but the order of emission is respected.\n Merge presents the result as they come in which is great if the disk is *always* faster. If not, you have problems.\n Here\\'s a fake example where the disk is made slower than the network call. You can see the results are whack.\n This is an optimized merge and probably want to use. Notice subscriptions happen immediately and network results are respected regardless of when they come in. So if the disk is slower, it is discarded.\n Similar to optimized merge (same code). Notice though that if the disk is slower it\\'s discarded in favor of the \"fresh\" network data which in this case happens to be faster.\n tap me\n Start long operation\n Enter some search text\n BTN 1\n BTN 2\n BTN 3\n BTN 4\n BTN 5\n CLEAR LOG\n 100\n +\n 8\n 0\n Retry\n Delay\n Enter a valid email below:\n than 8 chrs):]]>\n \n Submit\n Start simple polling\n Start increasingly delayed polling\n Info about the demo will show up here\n concat\n concat (eager)\n merge\n merge (slower disk)\n merge (optimized)\n merge (optimized) slow disk\n network call]]>\n Log contributors of:\n square\n owner\n retrofit\n reponame\n Log with full User Info:\n Log User Info:\n kaushikgopal\n Start operation\n 1\n tap!\n Button 1\n Button 2\n Start\n I AMZ BTN\n\n\n" }, { "path": "app/src/main/res/values/styles.xml", "content": "\n\n \n \n\n\n" }, { "path": "app/src/main/res/values-w820dp/dimens.xml", "content": "\n \n 64dp\n\n" }, { "path": "build.gradle", "content": "// Top-level build file where you can add configuration options common to all sub-projects/modules.\n\nbuildscript {\n repositories {\n jcenter()\n mavenCentral()\n }\n dependencies {\n classpath 'com.android.tools.build:gradle:2.3.3'\n classpath 'com.f2prateek.javafmt:javafmt:0.1.2'\n\n // NOTE: Do not place your application dependencies here; they belong\n // in the individual module build.gradle files\n }\n}\n\nallprojects {\n repositories {\n jcenter()\n maven { url 'https://maven.google.com' }\n maven {\n url \"https://jitpack.io\"\n }\n }\n\n ext {\n sdkVersion = 24\n buildToolsVrs = \"25.0.0\"\n\n kotlinVersion = \"1.1.3-2\"\n\n archComponentsVersion = \"1.0.0-alpha3\"\n butterKnifeVersion = '8.5.1'\n mockitoKotlinVersion = \"1.4.0\"\n okhttpVersion = \"3.0.1\"\n retrofitVersion = \"2.0.0\"\n supportLibVersion = \"25.3.1\"\n }\n}\n" }, { "path": "gradle/wrapper/gradle-wrapper.properties", "content": "#Wed May 24 09:29:38 PDT 2017\ndistributionBase=GRADLE_USER_HOME\ndistributionPath=wrapper/dists\nzipStoreBase=GRADLE_USER_HOME\nzipStorePath=wrapper/dists\ndistributionUrl=https\\://services.gradle.org/distributions/gradle-4.0-all.zip\n" }, { "path": "gradle.properties", "content": "# Project-wide Gradle settings.\n\n# IDE (e.g. Android Studio) users:\n# Settings specified in this file will override any Gradle settings\n# configured through the IDE.\n\n# For more details on how to configure your build environment visit\n# http://www.gradle.org/docs/current/userguide/build_environment.html\n\n# Specifies the JVM arguments used for the daemon process.\n# The setting is particularly useful for tweaking memory settings.\n# Default value: -Xmx10248m -XX:MaxPermSize=256m\n# org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8\n\n# When configured, Gradle will run in incubating parallel mode.\n# This option should only be used with decoupled projects.
