public class RetrieveFeedTask extends AsyncTask {

    private Exception exception;

    protected String doInBackground(Void... params) {

        JsonFactory jsonFactory = new JacksonFactory();

        try {
            List scopes = new ArrayList();

            scopes.add(StorageScopes.DEVSTORAGE_FULL_CONTROL);
            HttpTransport httpTransport = new com.google.api.client.http.javanet.NetHttpTransport();

            //convert key into class File. from inputstream to file. in an aux class.
            File file =getTempPkc12File();


            //Google Credentianls
            GoogleCredential credential = new GoogleCredential.Builder().setTransport(httpTransport)
                    .setJsonFactory(jsonFactory)
                    .setServiceAccountId("xxxxxx-xxxx-xxx@xxxxx-xxxxxx.iam.gserviceaccount.com")
                    .setServiceAccountScopes((scopes))
                    .setServiceAccountPrivateKeyFromP12File(file)
                    .build();




            String URI = "https://storage.googleapis.com/" + GOOGLE_STORAGE_BUCKET+"/images/"+createImageFile();
            HttpRequestFactory requestFactory = httpTransport.createRequestFactory(credential);


            GenericUrl url = new GenericUrl(URI);




            //byte array holds the data, in this case the image i want to upload in bytes.

            Resources res = getResources();
            Drawable drawable = res.getDrawable(R.drawable.camera);
            Bitmap bitmap = ((BitmapDrawable)drawable).getBitmap();
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
            byte[] bitMapData = stream.toByteArray();


            HttpContent contentsend = new ByteArrayContent("image/jpeg", bitMapData );


            HttpRequest putRequest;

            putRequest = requestFactory.buildPutRequest(url, contentsend);




            com.google.api.client.http.HttpResponse response = putRequest.execute();
            String content = response.parseAsString();
            Log.i("debug", "response is:"+response.getStatusCode());
            Log.i("debug", "response content is:"+content);
        } catch (IOException | GeneralSecurityException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            Log.i("ErrorUpload",""+e.toString());
        }
        return "";

    }

    protected void onPostExecute(String feed) {
        int i  = 0;
        int j = i;
        // TODO: check this.exception
        // TODO: do something with the feed
        Log.i("OnPost",""+feed);
    }
}


private  File getTempPkc12File() throws IOException {
    // xxx.p12 export from google API console
    InputStream pkc12Stream = (NewProduceInfo.this).getResources().getAssets().open("xxxxx-xxxxxxx-xxxxxx.p12");
    File tempPkc12File = File.createTempFile("temp_pkc12_file", "p12");
    OutputStream tempFileStream = new FileOutputStream(tempPkc12File);
    int read = 0;
    byte[] bytes = new byte[1024];
    while ((read = pkc12Stream.read(bytes)) != -1) {
        tempFileStream.write(bytes, 0, read);
    }
    return tempPkc12File;
}
