How to programmatically take a screenshot on Android? (24 answers)

Closed 5 years ago.

I want to take a fullscreen screenshot programmatically , for example, one of the android home screen or a menu. How can I get a view of the home screen in my application? I want to take it programmatically!!! It doesn't matter if it requires root mode!

Help me please and sorry for my English!

Use following code

Bitmap bitmap;
View v1 = MyView.getRootView();
v1.setDrawingCacheEnabled(true);
bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);

Here MyView is the View through which we need include in screen.

   OutputStream  os = sh.getOutputStream();
   os.write(("/system/bin/screencap -p " + "/sdcard/img.png").getBytes("ASCII"));
