Tesela is a code generate based library that helps you implement Model-View-Presenter pattern on Android. It let you annotate methods to make them be executed on UI thread or on a background thread. It will help you to keep a weak reference to the view, so forget about leaking your Fragment or Activity anymore while your background work finishes.
Example Proguard configurations for common Android libraries.
This project assumes that your ProGuard configuration is based off of the latest official proguard-android.txt config as shown below. Each library configuration should only be the rules required for that specific library, not a complete Android ProGuard configuration. The various library configurations are combined by the Gradle build system. The library rules should be universal, any app specific rules (such as preserving model classes) should be added in a custom proguard-project.pro file.
