deciphering crash report from Google Play

Question

I am receiving a crash report but it doesn't make sense to me. Says text may not be null. It works on any device I test with but somehow it is crashing for a few people. Latest one reported using a Galaxy Indulge (SCH-R910). Here is the report

java.lang.RuntimeException: An error occured while executing doInBackground()

And here is my code for the upload

class uploadthephoto extends AsyncTask<String, String, String> {

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        pDialog = new ProgressDialog(UploadPicture.this);
        pDialog.setMessage("Uploading Picture");
        pDialog.setIndeterminate(false);
        pDialog.setCancelable(true);
        pDialog.show();

    }

    @Override
    protected String doInBackground(String... args) {

        HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost(POST_COMMNT_URL);

        try {

            MultipartEntity entity = new MultipartEntity(
                    HttpMultipartMode.BROWSER_COMPATIBLE);
            File file = new File(theimagepath);
            cbFile = new FileBody(file, "image/jpeg");
            entity.addPart("username", new StringBody(username,
                    Charset.forName("UTF-8")));
            entity.addPart("name", new StringBody(name,
                    Charset.forName("UTF-8")));
            entity.addPart("album", new StringBody(spinselected, Charset.forName("UTF-8")));
            entity.addPart("picture", cbFile);
            post.setEntity(entity);


            HttpResponse response1 = client.execute(post);
            HttpEntity resEntity = response1.getEntity();
            String Response = EntityUtils.toString(resEntity);
            Log.d("Response", Response);

            json = new JSONObject(Response);
            success_number = json.getInt("success");

            if (success_number == 1) { // picture added!
                return json.getString("message");

            } else {
                Log.d("Login Failure!", json.getString(message));
                return json.getString("message");

            }

        } catch (IOException e) {
            Log.e("asdf", e.getMessage(), e);

        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return null;

    }

    protected void onPostExecute(String file_url) {
        pDialog.dismiss();
        if (file_url != null) {
            Toast.makeText(UploadPicture.this, file_url, Toast.LENGTH_LONG)
                    .show();
        }

    }
}

// Username is from SharedPreferences
// Name is from SharedPreferences
// Album is from a Spinner 
// Picture is chosen from their gallery

Any idea why it would throw this error on some devices? Thank you.

entity.addPart("album", new StringBody(spinselected, Charset.forName("UTF-8"))); — JeffK, Nov 26 '13 at 02:08
It comes from @Override public void onItemSelected(AdapterView> arg0, View arg1, int position, long arg3) { // TODO Auto-generated method stub spinselected = (String) upSpinner.getItemAtPosition(position); Log.d("spin selected", spinselected); } — JeffK, Nov 26 '13 at 02:08

It's this line:

entity.addPart("album", new StringBody(spinselected, Charset.forName("UTF-8")));

Apparently spinselected is null and StringBody throws an error if it is constructed with a null parameter.

Any clues why it could be okay with some devices and null with others? The spinner is populated from a database during the oncreate – JeffK Nov 26 '13 at 04:04
That I'm not too sure about. It's a bit of a bandaid at this point, but I would at least add a null check to make sure you don't crash. – James McCracken Nov 26 '13 at 04:08
