    private void pickOrTakePicture(int requestCode) {
        storeFolder = getCacheDir();
        Intent pickIntent = new Intent();
        pickIntent.setType("image/*");
        pickIntent.setAction(Intent.ACTION_GET_CONTENT);

        Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        pickFile = new File(storeFolder, ImageUtils.getHexRandomString(4) + ".jpg");
        try {

            pickFile.createNewFile();
            pickFile.setWritable(true, false);
        }
        catch(IOException e) {
            e.printStackTrace();
        }
        takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(pickFile));
        // String pickTitle = "Select or take a new Picture";
        String pickTitle = "";
        Intent chooserIntent = Intent.createChooser(pickIntent, pickTitle);
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] { takePhotoIntent });

        startActivityForResult(chooserIntent, requestCode);
    }



@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
 if (requestCode == REQUEST_PHOTO) {
            if (resultCode == RESULT_OK) {
                Uri iconUri;
                if (data != null && data.getData() != null) {
                    iconUri = data.getData();
                }
                else {
                    iconUri = Uri.fromFile(pickFile);
                }
}
