    public void takeScreenShot(final View view, final String name)
            throws Exception {

        getActivity().runOnUiThread(new Runnable() {
            @Override
            public void run() {
                view.setDrawingCacheEnabled(true);
                view.buildDrawingCache();
                Bitmap b = view.getDrawingCache();
                FileOutputStream fos = null;
                try {
                    final String path = Environment.getExternalStorageDirectory()+ "/test-screenshots/";
                    File dir = new File("/mnt/sdcard/test-screenshots");
                    if(!dir.mkdirs()){
                        System.out.println("Creaet sd card failed");
                    }

                    if (!dir.exists()) {
                        System.out.println(path);
                        dir.mkdirs();
                    }

                    fos = new FileOutputStream(path + name + ".jpg");
                    if (fos != null) {
                        b.compress(Bitmap.CompressFormat.JPEG, 90, fos);
                        fos.close();
                    }
                } catch (IOException e) {
                }
            }
        });

    }

}

You need add permission to write to the SD Card in the main application. Not the JUnit test project! Add this to the project manifest: <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
