# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
# within the Gradle project.
#
# You can find Gradle at https://github.com/gradle/gradle/.

Firebase Remote Config Quickstart
==============================
The Firebase Remote Config Android quickstart app demonstrates using Remote
Config to define user-facing text in an Android app.
Introduction
------------
This is a simple example of using Remote Config to override in-app default
values by defining service-side parameter values in the Firebase console. This
example demonstrates a small subset of the capabilities of Firebase Remote
Config. To learn more about how you can use Firebase Remote Config in your app,
see
[Firebase Remote Config Introduction](https://firebase.google.com/docs/remote-config/).
Getting started
---------------
1. [Add Firebase to your Android Project](https://firebase.google.com/docs/android/setup).
2. [Create a Remote Config project for the quickstart sample](https://firebase.google.com/docs/remote-config/android#create_a_product_name_project_for_the_quickstart_sample),
defining the parameter values and parameter keys used by the sample.
3. Run the sample on an Android device or emulator.
4. Change one or more parameter values in the Firebase Console (the value of
`welcome_message`, `welcome_message_caps`, or both).
5. Tap **Fetch Remote Config** in the app to fetch new parameter values and see
the resulting change in the app.
Best practices
--------------
This section provides some additional information about how the quickstart
example sets in-app default parameter values and fetches values from the Remote
Config service
### In-app default parameter values ###
In-app default values are set using an XML file in this example, but you can
also set in-app default values inline using other `setDefault` methods of the
[`FirebaseRemoteConfig` class](https://firebase.google.com/docs/reference/android/com/google/firebase/remoteconfig/FirebaseRemoteConfig#public-method-summary).
Then, you can override only those values that you need to change from the
Firebase console. This lets you use Remote Config for any default value that you
might want to override in the future, without the need to set all of those
values in the Firebase console.
### Fetch values from the Remote Config service ###
When an app calls `fetch`, locally stored parameter values are used unless the
minimum fetch interval is reached. The minimal fetch interval is determined by:
1. The parameter passed to `fetch(long minFetchInterval)`.
2. The minimum fetch interval set in Remote Config settings.
3. The default minimum fetch interval, 12 hours.
Fetched values are immediately activated when retrieved using `fetchAndActivate`.
`fetchAndActivate` returns true if the final set of key/value pairs now available
to the application is different to the set before calling `fetchAndActivate`, false
is returned otherwise. In the quickstart sample app, you call `fetchAndActivate`
from the UI by tapping **Fetch Remote Config**.
To control when fetched values are activated and available to your app use `fetch`, the
values are locally stored, but not immediately activated. To activate
fetched values so that they take effect, call the `activate` method.
You can also create a Remote Config Setting to enable developer mode, but you
must remove this setting before distributing your app. Fetching Remote Config
data from the service is normally limited to a few requests per hour. By
enabling developer mode, you can make many more requests per hour, so you can
test your app with different Remote Config parameter values during development.
- To learn more about fetching data from remote config, see the Remote Config
Frequently Asked Question (FAQ) on
[fetching and activating parameter values](https://firebase.google.com/support/faq#remote-config-values).
- To learn about parameters and conditions that you can use to change the
behavior and appearance of your app for segments of your userbase, see
[Remote Config Parameters and Conditions](https://firebase.google.com/docs/remote-config/parameters).
- To learn more about the Remote Config API, see
[Remote Config API Overview](https://firebase.google.com/docs/remote-config/api-overview).

# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
# within the Gradle project.

# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
# within the Gradle project.
#
# You can find Gradle at https://github.com/gradle/gradle/.

Firebase Database Quickstart
=============================
Introduction
------------
- [Read more about Firebase Database](https://firebase.google.com/docs/database)
Getting Started
---------------
- [Add Firebase to your Android Project](https://firebase.google.com/docs/android/setup).
- Log in to the [Firebase Console](https://console.firebase.google.com).
- Go to **Auth** tab and enable **Email/Password** authentication.
- Run the sample on Android device or emulator.
Result
-----------
/email` is the email address of the user with id=``.
* `posts` - a list of `Post` objects, keyed by randomly generated push ID.
Each `Post` contains the `uid` and `author` properties to determine the
identity of the author without a JOIN-style query.
* Posts contain a `stars` property which is a `Map` of user IDs to boolean
values. If `/posts//stars/` is `true`, this means
the user with ID `` has starred the post with ID ``.
This data nesting makes it easy to tell if a specific user has already
starred a specific post, but would not scale to large numbers of stars
per post as it would make loading the Post data more expensive.
* `user-posts` - a list of posts by the user. `/user-posts/` is a list
of all posts made by a specific user, keyed by the same push ID used in
the `posts` tree. This makes it easy to query "all posts by a specific
user" without filtering through all Post objects.
* `post-comments` - comments on a particular posts, where
`/post-comments/` is a list of all comments on post with id
``. Each comment has a randomly generated push key. By keeping
this data in its own tree rather than nesting it under `posts`, we make it
possible to load a post without loading all comments while still
having a known path to access all comments for a particular post.
Database Rules
---------------
Below are some samples rules that limit access and validate data:
```javascript
{
"rules": {
// User profiles are only readable/writable by the user who owns it
"users": {
"$UID": {
".read": "auth.uid == $UID",
".write": "auth.uid == $UID"
}
},
// Posts can be read by anyone but only written by logged-in users.
"posts": {
".read": true,
".write": "auth.uid != null",
"$POSTID": {
// UID must match logged in user and is fixed once set
"uid": {
".validate": "(data.exists() && data.val() == newData.val()) || newData.val() == auth.uid"
},
// User can only update own stars
"stars": {
"$UID": {
".validate": "auth.uid == $UID"
}
}
}
},
// User posts can be read by anyone but only written by the user that owns it,
// and with a matching UID
"user-posts": {
".read": true,
"$UID": {
"$POSTID": {
".write": "auth.uid == $UID",
".validate": "data.exists() || newData.child('uid').val() == auth.uid"
}
}
},
// Comments can be read by anyone but only written by a logged in user
"post-comments": {
".read": true,
".write": "auth.uid != null",
"$POSTID": {
"$COMMENTID": {
// UID must match logged in user and is fixed once set
"uid": {
".validate": "(data.exists() && data.val() == newData.val()) || newData.val() == auth.uid"
}
}
}
}
}
}
```

# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
# within the Gradle project.
#
# You can find Gradle at https://github.com/gradle/gradle/.

# Firebase Data Connect Quickstart
## Introduction
This quickstart is a movie review app to demonstrate the use of Firebase Data Connect
with a Cloud SQL database.
For more information about Firebase Data Connect visit [the docs](https://firebase.google.com/docs/data-connect/).
## Getting Started
Follow these steps to get up and running with Firebase Data Connect. For more detailed instructions,
check out the [official documentation](https://firebase.google.com/docs/data-connect/quickstart).
### 0. Prerequisites
- Latest version of [Android Studio](https://developer.android.com/studio)
- Latest version of [Visual Studio Code](https://code.visualstudio.com/)
- The [Firebase Data Connect VS Code Extension](https://marketplace.visualstudio.com/items?itemName=GoogleCloudTools.firebase-dataconnect-vscode)
### 1. Connect to your Firebase project
1. If you haven't already, create a Firebase project.
1. In the [Firebase console](https://console.firebase.google.com), click
**Add project**, then follow the on-screen instructions.
2. Upgrade your project to the Blaze plan. This lets you create a Cloud SQL
for PostgreSQL instance.
> Note: Though you set up billing in your Blaze upgrade, you won't be
charged for usage of Firebase Data Connect or the
[default Cloud SQL for PostgreSQL configuration](https://firebase.google.com/docs/data-connect/#pricing)
during the preview.
3. Navigate to the [Data Connect section](https://console.firebase.google.com/u/0/project/_/dataconnect)
of the Firebase console, click on the "Get Started" button and follow the setup workflow:
- Select a location for your Cloud SQL for PostgreSQL database (this sample uses `us-central1`). If you choose a different location, you'll also need to change the `quickstart-android/dataconnect/dataconnect/dataconnect.yaml` file.
- Select the option to create a new Cloud SQL instance and fill in the following fields:
- Service ID: `dataconnect`
- Cloud SQL Instance ID: `fdc-sql`
- Database name: `fdcdb`
4. Allow some time for the Cloud SQL instance to be provisioned. After it's provisioned, the instance
can be managed in the [Cloud Console](https://console.cloud.google.com/sql).
5. If you haven’t already, add an Android app to your Firebase project, with the android package name `com.google.firebase.example.dataconnect`.
Click **Download google-services.json** to obtain your Firebase Android config file.
### 2. Cloning the repository
1. Clone this repository to your local machine:
```sh
git clone https://github.com/firebase/quickstart-android.git
```
2. Move the `google-services.json` config file (downloaded in the previous step) into the
`quickstart-android/dataconnect/app/` directory.
### 3. Open in Visual Studio Code (VS Code)
1. Open the `quickstart-android/dataconnect` directory in VS Code.
2. Click on the Firebase Data Connect icon on the VS Code sidebar to load the Extension.
a. Sign in with your Google Account if you haven't already.
3. Click on "Connect a Firebase project" and choose the project where you have set up Data Connect.
4. Click on "Start Emulators" - this should generate the Kotlin SDK for you and start the emulators.
### 4. Populate the database
In VS Code, open the `quickstart-android/dataconnect/dataconnect/moviedata_insert.gql` file and click the
`Run (local)` button at the top of the file.
If you’d like to confirm that the data was correctly inserted,
open `quickstart-android/dataconnect/movie-connector/queries.gql` and run the `ListMovies` query.
### 5. Running the app
Press the Run button in Android Studio to run the sample app on your device.

#
# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
# within the Gradle project.
#
# You can find Gradle at https://github.com/gradle/gradle/.

Firebase Functions Quickstart
=============================
Introduction
------------
This quickstart demontstrates **Callable Functions** which are HTTPS Cloud Functions
that can be invoked directly from your mobile application.
- [Read more about callable functions](https://firebase.google.com/docs/functions/callable)
Getting Started
---------------
- [Add Firebase to your Android Project](https://firebase.google.com/docs/android/setup).
- Deploy the provided cloud functions:
```bash
# Move to the `functions` subdirectory of quickstart-android
cd functions
# Install all of the dependencies of the cloud functions
cd functions
npm install
cd ../
# Deploy functions to your Firebase project
firebase --project=YOUR_PROJECT_ID deploy --only functions
```
- Run the sample on Android device or emulator.
