prevent screen capture in Android apps

Question

I was wondering if there is a way to detect through some \"onXXXXX\" call-back method or received broadcast if some other process is about to take a screen-shot of my app\'

Answer 1

This worked for me on a Samsung Tab 2 7"

Using the following approach, to simply add the FLAG_SECURE to the Window Flags

public class FlagSecureTestActivity extends Activity {
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    getWindow().setFlags(LayoutParams.FLAG_SECURE,
                         LayoutParams.FLAG_SECURE);

    setContentView(R.layout.main);
  }
}

with the caveat that you may need to change

LayoutParams

to

WindowManager.LayoutParams
