Withings API integration in android

I am building Android App which shows Withings user's activity data in my Application.
But when I am trying to call refresh_token url:
https://oauth.withings.com/account/request_token?oauth_callback=******&oauth_consumer_key=******&oauth_nonce=******&oauth_signature=CcMrI7JaI8M5tEenye3s95wx%2BZ4%3D&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1477386344&oauth_version=1.0
Then I am getting Invalid Signature response like below:
{
"status":0,
"message":"Invalid signature :\n CcMrI7JaI8M5tEenye3s95wx+Z4= .. \n{\"oauth_callback\":\"******\",\"oauth_consumer_key\":\"ce54bd6c671546ef8f8d394c0db4bd86688289d5f7fb39f371c5ebce4d01\",\"oauth_nonce\":\"f339febe0fdf4b53b953501e45a049db\",\"oauth_signature\":\"CcMrI7JaI8M5tEenye3s95wx+Z4=\",\"oauth_signature_method\":\"HMAC-SHA1\",\"oauth_timestamp\":\"1477386344\",\"oauth_version\":\"1.0\"}\n{\"base_string\":\"GET&https%3A%2F%2Foauth.withings.com%2Faccount%2Frequest_token&oauth_callback%3D******%26oauth_consumer_key%3D******%26oauth_nonce%3Df339febe0fdf4b53b953501e45a049db%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1477386344%26oauth_version%3D1.0\"}\n{\"key\":\"******\",\"secret\":\"******\",\"callback_url\":null}"
}

First of all you can use the scribe lib
On my sample code I have an Authentication Activity that has an WebView that the user uses to verify the app. Then that Authentication Activity sends back to the MainActivity the response.
On my example I am storing locally on a DB the authenticated user to not ask every time the credentials.
Also I am sending the access token to python server that will get all data stored on Withings Cloud to save it to my Server DB and represent them on a Graph Activity. {I have removed that part}
Because of the copy paste maybe something is missing but most of the code is here
public class WithingsApi extends DefaultApi10a {
private static final String AUTHORIZATION_URL ="https://oauth.withings.com/account/authorize?oauth_token=%s";
private static final String apiKey = "API_KEY";

Asynchronous call to server being blocked by bluetooth LE Scan

I have an Activity which constructs a RESTManager class (used to make an asynchronous call to the server and return data to the Activity).
However, after I construct my RESTManager and call the server using
//Retrieve data from server
RESTManager m = new RESTManager(this,getApplicationContext());
//Set the data list
m.delegate=this;
m.retrieveRoomData();
the server call does not go through until I turn off bluetooth scanning.
However, I start my bluetooth scan immediately after the RESTManager as such:
beaconManager = BeaconManager.getInstanceForApplication(this);
beaconManager.setBackgroundScanPeriod(1100l);
beaconManager.setBackgroundBetweenScanPeriod(100l);
beaconManager.setForegroundScanPeriod(1100l);
beaconManager.setForegroundBetweenScanPeriod(100l);
//Set the custom BeaconLayout for iBeacons
if (myPref.getBoolean("layoutSet", true)) {
beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:0-3=4c000215,i:4-19,i:20-21,i:22-23,p:24-24"));
backgroundPowerSaver = new BackgroundPowerSaver(this);
Log.v("Beacon Layout", "Beacon Layout Set");
myPref.edit().putBoolean("layoutSet", false).apply();
myPref.edit().commit();
}
beaconManager.bind(this);
I am not getting any error.
Is there any reason why my AsyncTask from RESTManager would hang from the bluetooth scans?

Android - Tumblr Access Token via OAuth

I am trying to allow Android users to post to their Tumblr blogs using my app. I am able to launch Tumblr, enter my username and password, and log in, however the problem is the Access Token I receive appears to be invalid (I get a 401 - Unauthorized when I use it with any of Tumblr's API calls).
Below is the code I am using. I am able to authenticate with Twitter, but Tumblr is giving me difficulties. If anyone has any ideas, suggestions, or improvements, they would be much appreciated. Thanks!

OAuth token with Google Play Game Services

Is there a way to get the token that was used to log in the user with Google Play Game Services?
I'm looking for something like:
#Override
public void onSignInSucceeded() {
String email = getGamesClient().getCurrentAccountName();
String token = getGamesClient().getToken();
}
I need this to authenticate the user when they are contacting my own server.

This is how I managed to get the token:
#Override
public void onSignInSucceeded() {
String email = getGamesClient().getCurrentAccountName();
String scopes = getScopes();
new registerBackground(getApplicationContext()).execute(email, scopes);
}
private class registerBackground extends AsyncTask<String, Void, Void> {
Context context;
registerBackground (Context context) {
this.context = context;
}
#Override
protected Void doInBackground(String... params) {
try {
String oAuthToken = GoogleAuthUtil.getToken(context, params[0], params[1]);
...
catch (Exception e) {
e.printStackTrace();
}
}
