Summary: I started working on improving the `StatusBar` API and make it work on Android. I added support for `setColor`, `setTranslucent` (the status bar is still visible but the app can draw under) and `setHidden` on Android. Looking for feedback on how to improve the API before I put more time on this :). Right now I went for a cross platform API and functions that don't exist on a platform are just a no-op but I'm not sure it is the best choice since at the moment what is supported is very different between both platforms. I was wondering what you guys think and if it would be better off as 2 different modules. It is also possible to port some of the features I added for Android to iOS even if there is no 'standard' way to do it. Like `setColor` could be implemented by drawing a colored view under the status bar and translucent by adding/removing some padding.

Building React Native for Android
This guide contains instructions for building the Android code and running the sample apps.
Supported Operating Systems
This setup has only been tested on Mac OS so far.
Prerequisites
Assuming you have the Android SDK installed, run android to open the Android SDK Manager.
Make sure you have the following installed:
- Android SDK version 23 (compileSdkVersion in
build.gradle) - SDK build tools version 23.0.1 (buildToolsVersion in
build.gradle) - Android Support Repository >= 17 (for Android Support Library)
- Android NDK (download & extraction instructions here)
Point Gradle to your Android SDK: either have $ANDROID_SDK and $ANDROID_NDK defined, or create a local.properties file in the root of your react-native checkout with the following contents:
sdk.dir=absolute_path_to_android_sdk
ndk.dir=absolute_path_to_android_ndk
Example:
sdk.dir=/Users/your_unix_name/android-sdk-macosx
ndk.dir=/Users/your_unix_name/android-ndk/android-ndk-r10e
Run npm install
This is needed to fetch the dependencies for the packager.
cd react-native
npm install
Building from the command line
To build the framework code:
cd react-native
./gradlew :ReactAndroid:assembleDebug
To install a snapshot version of the framework code in your local Maven repo:
./gradlew :ReactAndroid:installArchives
Running the examples
To run the UIExplorer app:
cd react-native
./gradlew :Examples:UIExplorer:android:app:installDebug
# Start the packager in a separate shell:
# Make sure you ran npm install
./packager/packager.sh
# Open UIExplorer in your emulator, Menu button -> Reload JS should work
You can run any other sample app the same way, e.g.:
./gradlew :Examples:Movies:android:app:installDebug
Building from Android Studio
You'll need to do one additional step until we release the React Native Gradle plugin to Maven central. This is because Android Studio has its own local Maven repo:
mkdir -p /Applications/Android\ Studio.app/Contents/gradle/m2repository/com/facebook/react
cp -r ~/.m2/repository/com/facebook/react/gradleplugin /Applications/Android\ Studio.app/Contents/gradle/m2repository/com/facebook/react/
Now, open Android Studio, click Import Non-Android Studio project and find your react-native repo.
In the configurations dropdown, app should be selected. Click Run.
Installing the React Native .aar in your local Maven repo
In some cases, for example when working on the react-native-cli it's useful to publish a snapshot version of React Native into your local Maven repo. This way, Gradle can pick it up when building projects that have a Maven dependency on React Native.
Run:
cd react-native-android
./gradlew :ReactAndroid:installArchives
Troubleshooting
Gradle build fails in ndk-build. See the section about local.properties file above.
Gradle build fails "Could not find any version that matches com.facebook.react:gradleplugin:...". See the section about the React Native Gradle plugin above.
Packager throws an error saying a module is not found. Try running npm install in the root of the repo.
