I’ve modified the jukebox example to run on Android, but it segfaults miserably when trying to call the sp_session_create() function.
Basically – I have a helloworld Android app with a button. When pressed it calls this function, which crashes on sp_session_create():
JNIEXPORT void JNICALL Java_com_holidaystudios_unispot_uniSpot_prepareSpotify() {
sp_session *sp;
sp_error err;
const char *username = NULL;
const char *password = NULL;
username = __USERNAME;
password = __PASSWORD;
g_listname = __PLAYLIST;
UNISPOT_DEBUG("prepareSpotify() - 1\n");
audio_init(&g_audiofifo);
UNISPOT_DEBUG("prepareSpotify() - 2\n");
/* Create session */
spconfig.application_key_size = g_appkey_size;
UNISPOT_DEBUG("prepareSpotify() - 3 %d, %p, %p (%p)\n", g_appkey_size, &spconfig, &sp, sp_session_create);
err = sp_session_create(&spconfig, &sp);
UNISPOT_DEBUG("prepareSpotify() - 4\n");
.
.
.
Here’s the logcat output which shows the segfault:

Any ideas?
I finally figured out what the problem is. If your AndroidManifest.xml does not request the INTERNET permission (and possibly WRITE_EXTERNAL_STORAGE) it will crash… Unfortunately libspotify does not perform any checks on creating sockets and will therefore crash… I’d say it’s actually a bug in libspotify… But anyhoo – here’s what you need to add to your AndroidManifest.xml if you are having the same problem as I did:
Possibly also this:
