Try this :

private void takeScreenshot() {
    Date now = new Date();
    android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);

    try {
        // image naming and path  to include sd card  appending name you choose for file
        String mPath = Environment.getExternalStorageDirectory().toString() + "/" + now + ".jpg";

        // create bitmap screen capture
        View v1 = getWindow().getDecorView().getRootView();
        v1.setDrawingCacheEnabled(true);
        Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
        v1.setDrawingCacheEnabled(false);

        File imageFile = new File(mPath);

        FileOutputStream outputStream = new FileOutputStream(imageFile);
        int quality = 100;
        bitmap.compress(Bitmap.CompressFormat.JPEG, quality, outputStream);
        outputStream.flush();
        outputStream.close();

        openScreenshot(imageFile);
    } catch (Throwable e) {
        // Several error may come out with file handling or OOM
        e.printStackTrace();
    }
}

You can view the file like this :

private void openScreenshot(File imageFile) {
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_VIEW);
    Uri uri = Uri.fromFile(imageFile);
    intent.setDataAndType(uri, "image/*");
    startActivity(intent);
}

Add this permission to save your file :

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

  • I want to get bitmap not of the particular app but of any screen that is displayed to the user. Secondly i want to know do we need to develop a app to get bitmap of any android screen or can we do it through jar file also. – Gazal Oct 16 '15 at 05:05
  • @Gazal `I want to get bitmap not of the particular app but of any screen that is displayed to the user` In simple words: **you aren't allowed to**. – Phantômaxx Oct 16 '15 at 08:08
  • Can we take bitmap only for image not for android screen ? If so , then can we take pixel value directly from the screen without creating bitmap? – Gazal Oct 16 '15 at 09:02
