Dropbox com.android.packageinstaller.InstallAppProgress has leaked IntentReceiver

Unable to upload a file.
I am trying to upload a file to dropbox. I have configured manifest file, and written the below code. Please help me understand what I am missing here.

Debug Statements prove that the file is correct.

public class UploadDB2DropBox extends AsyncTask<Object, Void, String> {
    private Context context;
    private WakeLock wakeLock;

    final static private String APP_KEY = "something";
    final static private String APP_SECRET = "sometingmore";
    final static private AccessType ACCESS_TYPE = AccessType.APP_FOLDER;
    private DropboxAPI<AndroidAuthSession> mDBApi;

    public UploadDB2DropBox(Context context) {
        this.context = context;
        AppKeyPair appKeys = new AppKeyPair(APP_KEY, APP_SECRET);
        AndroidAuthSession session = new AndroidAuthSession(appKeys,
                ACCESS_TYPE);
        mDBApi = new DropboxAPI<AndroidAuthSession>(session);
        mDBApi.getSession().startOAuth2Authentication(context);
    }

    protected void onPreExecute() {
        super.onPreExecute();
        final PowerManager pm = (PowerManager) context
                .getSystemService(Context.POWER_SERVICE);
        wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "");
        wakeLock.acquire();
    }

    @Override

                "Database path "
                        + context.getDatabasePath(God.TABLE_ACTIVATIONS));
        FileInputStream inputStream;
        try {
            inputStream = new FileInputStream(file);

            Log.d(God.TAG, "Uploaded file is " + response.rev);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
            Log.e(God.TAG, "FileNotFoundException");
        } catch (DropboxException e) {
            e.printStackTrace();
            Log.e(God.TAG, "DropboxException");
        }
        return null;
    }

    protected void onPostExecute(String result) {
        super.onPostExecute(result);
        if (wakeLock.isHeld())
            wakeLock.release();
        God.notifyNewActivations(context);
        if (mDBApi.getSession().authenticationSuccessful()) {
            try {
                // Required to complete auth, sets the access token on the session
                mDBApi.getSession().finishAuthentication();

                String accessToken = mDBApi.getSession().getOAuth2AccessToken();
            } catch (IllegalStateException e) {
                Log.i(God.TAG, "Error authenticating", e);
            }
        }
    }
}

I am getting a exception at DropboxException_ONE_LINE_BELOW. Below is the exception.
