Good day everyone, I would like to ask, hat is the cause of that ANR?. In my project I have service which is binded in a activity. Now when I exit in that activity the app is hang for a moment. My thought is that the service is still running though I unbind it in onStop() of the activity.
Here is my service class

Register a new user on ejabberd server in android

I am facing the problem to create a new user on ejabberd server but sign in is working fine. i used the github repository (https://github.com/dilicode/LetsChat) for register the new user and chat between two and more users. I search on intenet, i found some way to register those are:
1.add
%% In-band registration
{access, register, [{allow, all}]}.
in access rules in ejabberd server and
2. also add
{mod_register, [
{access_from, register},
...
] ...
it in access rules of ejabberd server.

After struggle i found solution of this kind of problem. we need to do server side changes like:
step1:
step2:
step3:
after doing all these steps we will able to register new user on ejabberd server.

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

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
