- * Created by Allan Wang on 2017-06-28.
- *
- * Floating About Activity Panel for your app
- * This contains all the necessary layouts, and can be extended and configured using the [configBuilder]
- * The [rClass] is necessary to generate the list of libraries used in your app, and should point to your app's
- * R.string::class.java
- * If you don't need auto detect, you can pass null instead
- * Note that for the auto detection to work, the R fields must be excluded from Proguard
- * Manual lib listings and other extra modifications can be done so by overriding the open functions
