I'm trying to build an app using stackexchange api and user will able to use app after authenticating them self with stackoverflow.com . But problem here i am getting is after completing authentication when app is reopened and i am looking for data in intent in onResume() so it is null but is should consist a callback url with access token. when i open url which i passed to intent for authentication into browser so with callback url access_token is associated but in app i am getting null!
MainAcitivity
public class MainActivity extends AppCompatActivity {
private static final String TAG = "MainActivity";
Uri uri = new Uri.Builder()
.scheme("https")
.authority("stackoverflow.com")
.appendPath("oauth").appendPath("dialog")
.appendQueryParameter("client_id", "14910")
.appendQueryParameter("scope", "read_inbox")
.appendQueryParameter("redirect_uri", "https://stackoverflow.com/oauth/login_success")
.build();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.d(TAG, "onCreate: uri : " + uri);
Intent intent = new Intent(
Intent.ACTION_VIEW,
uri);
startActivity(intent);
}
@Override
protected void onResume() {
super.onResume();
Log.d(TAG, "onResume: intent: " + getIntent());
Log.d(TAG, "onResume: uri: " + getIntent().getData());
Uri uri = getIntent().getData();
if (uri != null && uri.toString().startsWith("stackoverflow.com/oauth/login_success")) {
String code = uri.getQueryParameter("code");
if (code != null) {
Log.d(TAG, "onResume: code:" + code);
} else if (uri.getQueryParameter("error") != null) {
Log.d(TAG, "onResume: error" + uri.getQueryParameter("error"));
}
}else{
Log.d(TAG, "onResume: else");
}
}
