I’m writing a NDK wrapper around libspotify on Android. But sp_session_callbacks:: logged_in callback never called.
This is content of tracefile:
libspotify trace from 12.1.51.g86c92b43 Release Android-arm
< sp_session_create() = 0
> sp_session_login(0x240ea8 'moodstream1@gmail.com' '<hidden>' 0) on 0x400fc4c8
This is a log received with sp_session_callbacks:: log_message callback.
13:30:07.361 I [offline_authorizer.cpp:297] Unable to login offline: no such user
13:30:07.372 I [ap:1752] Connecting to AP ap.spotify.com:4070

13:30:07.526 I [ap:1226] Connected to AP: 193.182.8.10:4070
As you see session was created correctly.
I’ve tested on real devices and emulator. The result is the same. Any ideas?
The problem could be that they are not driving libspotify properly. This is one of the common problems that people have.
Specifically it is important to listen to the notify_main_thread callback. This indicates that libspotify needs to process some data from the GUI main thread.
sp_session_process_events should then be called from the GUI main thread. sp_session_process_events must also be called periodically based on the next_timeout value returned
The faq covers this https://developer.spotify.com/technologies/libspotify/faq/ and the sp_shell examples serves as an illustration.
