Answer

If I have understood your question properly then, I assume you want your pictureFile name to be appended by an integer (in auto-incrementing fashion).

You could do that by maintaining a global variable as int imageCount = 1

and then appending it while creating fileName

int imageCount = 1;

private File saveBitMap(Context context, View drawView) {

    File pictureFileDir = new File(Environment.getExternalStorageDirectory()+"/"+"Frames");

    if (!pictureFileDir.exists()) {
        boolean isDirectoryCreated = pictureFileDir.mkdirs();
        if(!isDirectoryCreated) {
            Log.i("ATG", "Can't create directory to save the image");
        }
        return null;
    }
    String filename = pictureFileDir.getPath() +File.separator+"Frame"+ System.currentTimeMillis()+""+(imageCount++)+".jpg";
    File pictureFile = new File(filename);
    Bitmap bitmap =getBitmapFromView(drawView);
    try {
        pictureFile.createNewFile();
        FileOutputStream oStream = new FileOutputStream(pictureFile);
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, oStream);
        oStream.flush();
        oStream.close();
    } catch (IOException e) {
        e.printStackTrace();
        Log.i("TAG", "There was an issue saving the image.");
    }
    scanGallery( context,pictureFile.getAbsolutePath());
    return pictureFile;
}
