/**
* Interface for accessing and interacting with development features. Following features
* are supported through this manager class:
* 1) Displaying JS errors (aka RedBox)
* 2) Displaying developers menu (Reload JS, Debug JS)
* 3) Communication with developer server in order to download updated JS bundle
* 4) Starting/stopping broadcast receiver for js reload signals
* 5) Starting/stopping motion sensor listener that recognize shake gestures which in turn may
* trigger developers menu.
* 6) Launching developers settings view
*
* This class automatically monitors the state of registered views and activities to which they are
* bound to make sure that we don't display overlay or that we we don't listen for sensor events
* when app is backgrounded.
*
* {@link ReactInstanceDevCommandsHandler} implementation is responsible for instantiating this
* instance and for populating with an instance of {@link CatalystInstance} whenever instance
* manager recreates it (through {@link #onNewCatalystContextCreated}). Also, instance manager is
* responsible for enabling/disabling dev support in case when app is backgrounded or when all the
* views has been detached from the instance (through {@link #setDevSupportEnabled} method).
*
* IMPORTANT: In order for developer support to work correctly it is required that the
* manifest of your application contain the following entries:
* {@code <activity android:name="com.facebook.react.devsupport.DevSettingsActivity"/>}
* {@code <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>}
