Take screenshot programmatically of the whole screen

Question

I\'m taking screenshot as below:

 public static Bitmap takeScreenshot(Activity activity) {  
      View view = activity.getWindow().getDecorView();  
      v         


        

Answer 1

Read somewhere on the forums about another way: -

Process sh = Runtime.getRuntime().exec("su", null,null);
OutputStream  os = sh.getOutputStream();
os.write(("/system/bin/screencap -p " + "/sdcard/img.png").getBytes("ASCII"));
os.flush();

You can try that out. Don't know if it works or not, just saved it for a rainy day :P.

EDIT:

Found the link to the post - How to take a screenshots?

User says, screenshots work for him. I think this should suit your requirement.

Answer 2

It seems there is no way to get screenshot from screen of a device that is not rooted.Here,CommonsWare says:

If you mean "screenshot of somebody else's activity", that is not supported, for obvious privacy and security reasons.

Although you can get screenshot of emulator when your App is running!

Edit:

But there exists a library that is called ASL(Android Screenshot Library):

Android Screenshot Library (ASL) enables to programmatically capture screenshots from Android devices without requirement of having root access privileges. Instead, ASL utilizes a native service running in the background, started via the Android Debug Bridge (ADB) once per device boot.

I did not try it,but you can see more details in about it here.
