Uploading image from Android to GCS

I am trying to upload an image from Android directly to Google cloud storage. But the API does not seem to work. They have some Java samples which are tied to the App engine. I don't see any sample which is proven to work on Android.

On Android, I tried using the json api to upload an image. I am able to upload an image object but it seems to be corrupt. Moreover generating the authentication token seems to be tricky too.

I am struck with this right now. Did anyone on this earth ever tried uploading an image/video from Android using Java client or Json API and succeeded? Can someone point me in the right direction please. It has been very disappointing experience with this Storage api from Google. Please share your experiences if someone did it.
Below is the code that I am trying from Android while trying to use the GCS's JSON API.

private static String uploadFile(RichMedia media) {
DefaultHttpClient client = new DefaultHttpClient();
Bitmap bitmap = BitmapUtils.getBitmap(media.getLocalUrl());
HttpPost post = new HttpPost(GCS_ROOT + media.getLocalUrl() + "_" + System.currentTimeMillis());
if(media.getType() == RichMedia.RichMediaType.PICTURE) {
post.setHeader("Content-Type", "image/jpeg");
} else {
post.setHeader("Content-Type", "video/mp4");
}
post.setHeader("Authorization", "AIzaSyCzdmCMwiMzl6LD7R2obF0xSgnnx5rEfeI");
//post.setHeader("Content-Length", String.valueOf(bitmap.getByteCount()));
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] byteArray = stream.toByteArray();

try {
post.setEntity(new StringEntity(new Gson().toJson(byteArray).toString()));
HttpResponse response = client.execute(post);
BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
String eachLine = null;
StringBuilder builder = new StringBuilder();
while ((eachLine = reader.readLine()) != null) {
builder.append(eachLine);
}
L.d("response = " + builder.toString());
JSONObject object = new JSONObject(builder.toString());
String name = object.getString("name");
return name;
} catch (IOException e) {
L.print(e);
} catch (JSONException e) {
L.print(e);
}
return null;
}


I am running into two issues here.


  1. The file which got uploaded to the server is corrupt. It is not the same image that I uploaded. It is currupt.

  2. The authorization key expires very often. In my case, I am using the auth code generated by gsutil.


Answer

Since no one is answering this question, let me update the way I solved this problem. I ended up following this https://github.com/pliablematter/simple-cloud-storage project.

I could upload Pictures/Videos to GCS from my Android app.
