+/**
+ * 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".
