Gist which should prevent leaks of Activity in ClipboardUIManager.

ExampleApplication.java

public class ExampleApplication extends Application {
  @Override public void onCreate() {
    super.onCreate();
    if (Build.VERSION.SDK_INT >= 21) {
        try {
          Class<?> cls = Class.forName("android.sec.clipboard.ClipboardUIManager");
          Method m = cls.getDeclaredMethod("getInstance", Context.class);
          m.setAccessible(true);
          Object o = m.invoke(null, this);
      } catch (Exception ignored) { }
    }

  }
}

I hava a question about why limit the SDK version to 21 ?
