November, 9 2022 ### Fixed: - Ensure the main scheduler can be replaced in unit tests without needing Robolectric. ### Version 3.0.1 - November, 8 2022 ### Fixed: - `AndroidSchedulers.mainThread()` now correctly checks whether async messages are supported by the current Android version. Previously it always assumed they were available (true on API 16+). Changed: - Update to RxJava 3.1.5. This includes a transitive dependency bump to Reactive-Streams 1.0.4 which re-licenses that dependency from CC-0 to MIT-0. ### Version 3.0.0 - February, 14 2020 ### General availability of RxAndroid 3.0 for use with RxJava 3.0! The Maven groupId has changed to `io.reactivex.rxjava3` and the package is now `io.reactivex.rxjava3.android`. The APIs and behavior of RxAndroid 3.0.0 is otherwise exactly the same as RxAndroid 2.1.1 with one notable exception: Schedulers created via `AndroidSchedulers.from` now deliver [async messages](https://developer.android.com/reference/android/os/Handler.html#createAsync(android.os.Looper)) by default. This is also true for `AndroidSchedulers.mainThread()`. For more information about RxJava 3.0 see [its release notes](https://github.com/ReactiveX/RxJava/releases/tag/v3.0.0). --- Version 2.x can be found at https://github.com/ReactiveX/RxAndroid/blob/2.x/CHANGES.md Version 1.x can be found at https://github.com/ReactiveX/RxAndroid/blob/1.x/CHANGES.md ================================================ FILE: CONTRIBUTING.md ================================================ # Contributing to RxJava If you would like to contribute code you can do so through GitHub by forking the repository and sending a pull request (on a branch other than `master` or `gh-pages`).

This module adds the minimum classes to RxJava that make writing reactive components in Android applications easy and hassle-free. More specifically, it provides a `Scheduler` that schedules on the main thread or any given `Looper`. ## Communication Since RxAndroid is part of the RxJava family the communication channels are similar: - Google Group: [RxJava][list] - Twitter: [@RxJava][twitter] - StackOverflow: [rx-android][so] - [GitHub Issues][issues] # Binaries ```groovy dependencies { implementation 'io.reactivex.rxjava3:rxandroid:3.0.2' // Because RxAndroid releases are few and far between, it is recommended you also // explicitly depend on RxJava's latest version for bug fixes and new features. // (see https://github.com/ReactiveX/RxJava/releases for latest 3.x.x version) implementation 'io.reactivex.rxjava3:rxjava:3.1.5' } ``` * RxAndroid: * RxJava: Additional binaries and dependency information for can be found at [search.maven.org](http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22io.reactivex.rxjava3%22%20a%3A%22rxandroid%22).
Snapshots of the development version are available in Sonatype's snapshots repository.

```groovy repositories { mavenCentral() maven { url 'https://oss.sonatype.org/content/repositories/snapshots/' } } dependencies { implementation 'io.reactivex.rxjava3:rxandroid:3.1.0-SNAPSHOT' } ```

## Build To build: ```bash $ git clone git@github.com:ReactiveX/RxAndroid.git $ cd RxAndroid/ $ ./gradlew build ``` Further details on building can be found on the RxJava [Getting Started][start] page of the wiki. # Sample usage A sample project which provides runnable code examples that demonstrate uses of the classes in this project is available in the `sample-app/` folder. ## Observing on the main thread One of the most common operations when dealing with asynchronous tasks on Android is to observe the task's result or outcome on the main thread. Using vanilla Android, this would typically be accomplished with an `AsyncTask`. With RxJava instead you would declare your `Observable` to be observed on the main thread: ```java Observable.just("one", "two", "three", "four", "five") .subscribeOn(Schedulers.newThread()) .observeOn(AndroidSchedulers.mainThread()) .subscribe(/* an Observer */); ``` This will execute the `Observable` on a new thread, and emit results through `onNext` on the main thread. ## Observing on arbitrary loopers The previous sample is merely a specialization of a more general concept: binding asynchronous communication to an Android message loop, or `Looper`. In order to observe an `Observable` on an arbitrary `Looper`, create an associated `Scheduler` by calling `AndroidSchedulers.from`: ```java Looper backgroundLooper = // ... Observable.just("one", "two", "three", "four", "five") .observeOn(AndroidSchedulers.from(backgroundLooper)) .subscribe(/* an Observer */) ``` This will execute the Observable on a new thread and emit results through `onNext` on whatever thread is running `backgroundLooper`. ## Bugs and Feedback For bugs, feature requests, and discussion please use [GitHub Issues][issues]. For general usage questions please use the [mailing list][list] or [StackOverflow][so]. ## LICENSE Copyright 2015 The RxAndroid authors Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.

Ensure `VERSION_NAME` in `gradle.properties` is set to the version you want to release. 2. Add an entry in `CHANGELOG.md` with the changes for the release. 3. Update `README.md` with the version about to be released. Also update the RxJava version in this file to its latest. 4. Update the RxJava version in `rxandroid/build.gradle` to its latest. (We tell people that we won't be tracking RxJava releases, and we don't, but we do it anyway when we are releasing for those who ignore the advice.) 5. Commit: `git commit -am "Prepare version X.Y.X"` 6. Tag: `git tag -a X.Y.Z -m "Version X.Y.Z"` 7. Update `VERSION_NAME` in `gradle.properties` to the next development version. You MUST include `-SNAPSHOT` on the new version. 8. Commit: `git commit -am "Prepare next development version."` 9. Push: `git push && git push --tags` 10. Paste the `CHANGELOG.md` contents for this version into a Release on GitHub along with the Groovy for depending on the new version (https://github.com/ReactiveX/RxAndroid/releases). ================================================ FILE: build.gradle ================================================ buildscript { repositories { google() mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:4.2.2' classpath 'com.vanniktech:gradle-maven-publish-plugin:0.18.0' } } allprojects { repositories { google() mavenCentral() } tasks.withType(Test).configureEach { testLogging { if (System.getenv("CI") == "true") { events = ["failed", "skipped", "passed"] } exceptionFormat "full" } } } ext { minSdkVersion = 9 compileSdkVersion = 31 sourceCompatibility = JavaVersion.VERSION_1_8 } ================================================ FILE: gradle/wrapper/gradle-wrapper.properties ================================================ distributionBase=GRADLE_USER_HOME distributionPath=wrapper/dists distributionUrl=https\://services.gradle.org/distributions/gradle-6.9.1-bin.zip zipStoreBase=GRADLE_USER_HOME zipStorePath=wrapper/dists ================================================ FILE: gradle.properties ================================================ org.gradle.jvmargs=-Xmx2048m android.useAndroidX=true android.enableJetifier=false android.defaults.buildfeatures.buildconfig=false android.defaults.buildfeatures.aidl=false android.defaults.buildfeatures.renderscript=false android.defaults.buildfeatures.resvalues=false android.defaults.buildfeatures.shaders=false GROUP=io.reactivex.rxjava3 VERSION_NAME=3.1.0-SNAPSHOT POM_NAME=RxAndroid POM_DESCRIPTION=RxAndroid POM_URL=https://github.com/ReactiveX/RxAndroid POM_SCM_URL=https://github.com/ReactiveX/RxAndroid POM_SCM_CONNECTION=scm:git:https://github.com/ReactiveX/RxAndroid.git POM_SCM_DEV_CONNECTION=scm:git:git@github.com:ReactiveX/RxAndroid.git POM_LICENCE_NAME=The Apache Software License, Version 2.0 POM_LICENCE_URL=https://www.apache.org/licenses/LICENSE-2.0.txt POM_LICENCE_DIST=repo POM_DEVELOPER_ID=reactivex POM_DEVELOPER_NAME=ReactiveX POM_DEVELOPER_URL=https://github.com/ReactiveX ================================================ FILE: gradlew ================================================ #!/usr/bin/env sh # # Copyright 2015 the original author or authors. # # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. # You may obtain a copy of the License at # # https://www.apache.org/licenses/LICENSE-2.0 # # Unless required by applicable law or agreed to in writing, software # distributed under the License is distributed on an "AS IS" BASIS, # WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. # See the License for the specific language governing permissions and # limitations under the License. # ############################################################################## ## ## Gradle start up script for UN*X ## ############################################################################## # Attempt to set APP_HOME # Resolve links: $0 may be a link PRG="$0" # Need this for relative symlinks. while [ -h "$PRG" ] ; do ls=`ls -ld "$PRG"` link=`expr "$ls" : '.*-> \(.*\)$'` if expr "$link" : '/.*' > /dev/null; then PRG="$link" else PRG=`dirname "$PRG"`"/$link" fi done SAVED="`pwd`" cd "`dirname \"$PRG\"`/" >/dev/null APP_HOME="`pwd -P`" cd "$SAVED" >/dev/null APP_NAME="Gradle" APP_BASE_NAME=`basename "$0"` # Add default JVM options here.
