| /** |
| * 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> |
