Answer 1

Something like that should work :

http://developer.android.com/reference/android/view/View.html#getDrawingCache(boolean)

public void toJPEGFile(){
    File folder = new File(Environment.getExternalStorageDirectory()+"/folder/");
    if(!folder.exists()) folder.mkdirs();

    try {
        this.setDrawingCacheEnabled(true);
        FileOutputStream fos = new FileOutputStream(new File(Environment.getExternalStorageDirectory()+"/folder/file"));
        Bitmap bitmap = this.getDrawingCache();
        bitmap.compress(CompressFormat.JPEG, 100, fos);
        fos.flush();
        fos.close();
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }



}
