## Exporting an Android emulator build from Reactive Native

1. Create an assets folder under android/app/src/main/ if necessary.

mkdir android/app/src/main/assets

3. Go to the android folder.

cd android

4. Build the .apk file with Gradle.

./gradlew assembleDebug

5. You can find the resulting .apk file android/appbuild/outputs/apk/debug/app-debug.apk.
