### Generating the release APK
#### If you have a `react.gradle` file in `android/app`
Simply run the following in a terminal:
```sh
$ cd android && ./gradlew assembleRelease
```
If you need to change the way the JavaScript bundle and/or drawable resources are bundled (e.g. if you changed the default file/folder names or the general structure of the project), have a look at `android/app/build.gradle` to see how you can update it to reflect these changes.
Gradle's `assembleRelease` will bundle all the JavaScript needed to run your app into the APK. If you need to change the way the JavaScript bundle and/or drawable resources are bundled (e.g. if you changed the default file/folder names or the general structure of the project), have a look at `android/app/build.gradle` to see how you can update it to reflect these changes.
#### If you *don't* have a `react.gradle` file:
You can [upgrade](docs/upgrading.html) to the latest version of React Native to get this file. Alternatively, you can bundle the JavaScript package and drawable resources manually by doing the following in a terminal:
```sh
$ mkdir -p android/app/src/main/assets
$ react-native bundle --platform android --dev false --entry-file index.android.js \
--bundle-output android/app/src/main/assets/index.android.bundle \
--assets-dest android/app/src/main/res/
$ cd android && ./gradlew assembleRelease
```
In both cases the generated APK can be found under `android/app/build/outputs/apk/app-release.apk`, and is ready to be distributed.

_**IMPORTANT**: Make sure to thoroughly test your app if you've enabled Proguard. Proguard often requires configuration specific to each native library you're using. See `app/proguard-rules.pro`._
To enable Proguard, set `minifyEnabled` to `true`:
To enable Proguard, edit `android/app/build.gradle`:
```gradle
