I didnt downvoted it, but I can clearly see the reason why other people would do it; the question does not show any kind of effort or whatsoever. — AlvaroSantisteban, May 26 '15 at 11:11
the given sample not working fine,its throwing some error like source not found @ this line bitmap = Bitmap.createBitmap(v1.getDrawingCache()); and also i used View v1 = getWindow().getDecorView().getRootView(); instead of View v1 = mCurrentUrlMask.getRootView(); because its throwing some error — golla raghu, May 26 '15 at 11:20
@AlvaroSantisteban i had tried different examples but they didnt work for me,thats why i posted here with my requirement,it is difficult to post all the examples what i had tried — golla raghu, May 26 '15 at 11:22

Bitmap bitmap;
View v1 = findViewById(R.id.rlid);// get ur root view id
v1.setDrawingCacheEnabled(true); 
bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);

For saving

 ByteArrayOutputStream bytes = new ByteArrayOutputStream();
 bitmap.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
 File f = new File(Environment.getExternalStorageDirectory()
                + File.separator + "test.jpg")
 f.createNewFile();
 FileOutputStream fo = new FileOutputStream(f);
 fo.write(bytes.toByteArray()); 
 fo.close();

dont forget to give permission

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

From How to programatically take a screenshot on Android?

Here is the sample code:

// image naming and path  to include sd card  appending name you choose for file
String mPath = Environment.getExternalStorageDirectory().toString() + "/" + ACCUWX.IMAGE_APPEND;   
// create bitmap screen capture
Bitmap bitmap;
View v1 = getWindow().getDecorView().getRootView();
v1.setDrawingCacheEnabled(true);
bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);

OutputStream fout = null;
imageFile = new File(mPath);

try {
  fout = new FileOutputStream(imageFile);
  bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fout);
  fout.flush();
  fout.close();

} catch (FileNotFoundException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
} catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
}

For this you need this permission in manifest

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Insted of mCurrentUrlMask you can use like this View v1 = getWindow().getDecorView().getRootView(); — King of Masses, May 26 '15 at 12:47
I had tried but its throwing an error NullException at line bitmap = Bitmap.createBitmap(v1.getDrawingCache()); and i changed these lines in your code String mPath=Environment.getExternalStorageDirectory().toString() + "/" +"test.png"; and File imageFile = new File(mPath); — golla raghu, May 26 '15 at 13:38
