+
+If you have to change Android native code, you must have a look at the code in `android/src/main/java/` folder.
+
+## Run the example app
+
+At the root folder, run:
+```
+$ yarn clean:install
+```
+
+Make sure to have an emulator running or an Android device connected, and then:
+
+```
+$ cd example/
+$ react-native run-android
+```
+
+This will build the Android library (via `gradle`) and example app, then launch the main example activity on your connected device and run the Metro bundler at the same time.
+
+
+## FAQ / Troubleshooting
+
+Q: The example app doesn't run
+
+A: Make sure you have yarn and babel installed (https://yarnpkg.com/lang/en/docs/install/)
+
+
+Q: The example app gets compiled but ReactNative cannot connect to Metro bundler (I'm on a real device attached through USB)
+
+A: To debug on the device through USB, remember to revert ports before launching metro:
+`adb reverse tcp:8081 tcp:8081`
+
+
+Q: The example app gets compiled but ReactNative shows an error 
+
+A: try running, from the root folder in the project
+```
+yarn clean
+yarn
+cd example/
+yarn start --reset-cache
+```
+This will start metro in this window, then compile/run the app with the following command:
+```
+yarn android # in another shell
+```
