+/**
+ * Annotation used for marking methods and fields that are called from native
+ * code. Useful for keeping components that would otherwise be removed by
+ * Proguard. Use the value parameter to mention a file that calls this method.
+ *
+ * Note that adding this annotation to a method is not enough to guarantee that
+ * it is kept - either its class must be referenced elsewhere in the program, or
+ * the class must be annotated with this as well.
+ *
+ * Usage example:<br />
+ *  <pre>{@code
+ *  @UsedByNative("NativeCrashHandler.cpp")
+ * public static void reportCrash(int signal, int code, int address) {
+ * ...
+ * }
+ * </pre>
