Remarks

• You can launch the MiniApp located in the current working directory or on a connected Android device or running emulator if available. If a connected Android device is not available, the command prompts you to select an emulator to launch from the list of installed emulator images.
• The first time you run this command from within a MiniApp directory, it generates an Android directory containing the Android runner application project. If the Android folder already exists (it is not the first run of the ern run-android command for this MiniApp), the existing runner project is used.
• After the runner project is generated, you can safely make native code modifications to it, knowing that the next time the ern run-android command is issued, the project and your changes will remain.
• If you want to regenerate the runner project from scratch, remove the Android directory.
• The miniapp can be any Yarn package descriptor, including Git or other file system path schemes.
• The ern run-android command is the ern equivalent of the react-native run-android command.
