Summary: public React allows excluding certain elements from touch handling by assigning `PointerEvents` filter to them, such as BOX_NONE - this element will not receive touch but its children will, BOX_ONLY - only this element will receive pointer event and not children, NONE - neither this element nor its children will receive pointer events, and AUTO - pointer events are allowed for both this element and its children. This diff adds PointerEvents support to flat RCTView. Most of the implementation is copied from ReactViewManager/ReactViewGroup. One small change is made to TouchTargetHelper to ensure that it works correctly with virtual nodes when their parent has PointerEvents set to PointerEvents.BOX_NONE.

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.
