Is it possible to programmatically take a screenshot of an activity that is currently not displayed? Maybe using findViewById()?

I would want my app to take a screenshot of another activity after a button press in the current activity.

Why won't something like this work?

    Bitmap screen; View v1 = findViewById(R.id.someView);
    v1.setDrawingCacheEnabled(true);
    screen = Bitmap.createBitmap(v1.getDrawingCache());
    v1.setDrawingCacheEnabled(false);

  • Sorry, that was poorly worded. Let's say I have activity1 and it has a button that says "take screenshot". I also have activity2 in my app that has some content (like graphs). My goal is when the user presses the screenshot button in activity1, the application takes a screenshot of activity2. I don't know if this is even possible and that's why I asked :) – cashmoneyscience Jun 13 '17 at 10:45

If the other Activity is running in the background, you can convert the View into Bitmap by notifying it via LocalBroadcast events. cheers :)
