Elimates 304 methods based on dex analysis The java compiler generates sythetic accessor methods for all private fields, methods and contructors accessed from inner classes. By marking them package-private and @Thunk instead, sythentic accessor methods are no longer needeed. These annotated elements should be treated as private.

/**
|
|
* Indicates that the given field or method has package visibility solely to prevent the creation
|
|
* of a synthetic method. In practice, you should treat this field/method as if it were private.
|
|
* <p>
|
|
*
|
|
* When a private method is called from an inner class, the Java compiler generates a simple
|
|
* package private shim method that the class generated from the inner class can call. This results
|
|
* in unnecessary bloat and runtime method call overhead. It also gets us closer to the dex method
|
|
* count limit.
|
|
* <p>
|
|
*
|
|
* If you'd like to see warnings for these synthetic methods in eclipse, turn on:
|
|
* Window > Preferences > Java > Compiler > Errors/Warnings > "Access to a non-accessible member
|
|
* of an enclosing type".
