我调用RegistrationIntentService：
if (checkPlayServices()) {
Log.i("udazzT", "check servicies");
// Start IntentService to register this application with GCM.
Intent intent2 = new Intent(this, RegistrationIntentService.class);
startService(intent2);
}
但我无法在RegistrationIntentService中看到任何日志：
public class RegistrationIntentService extends IntentService {
private static final String TAG = "RegIntentService";
private static final String[] TOPICS = {"global"};
public RegistrationIntentService() {
super(TAG);
}
@Override
protected void onHandleIntent(Intent intent) {
Log.i("udazzT", "setting token");
SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);
try {
// In the (unlikely) event that multiple refresh operations occur simultaneously,
// ensure that they are processed sequentially.
synchronized (TAG) {
// [START register_for_gcm]
// Initially this call goes out to the network to retrieve the token, subsequent calls
// are local.
// [START get_token]
Log.i("udazzT", "setting token 2");
InstanceID instanceID = InstanceID.getInstance(this);
String token = instanceID.getToken(getString(R.string.gcm_defaultSenderId),
GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
// [END get_token]
Log.i(TAG, "GCM Registration Token: " + token);
// TODO: Implement this method to send any registration to your app's servers.
sendRegistrationToServer(token);
// Subscribe to topic channels
subscribeTopics(token);
// You should store a boolean that indicates whether the generated token has been
// sent to your server. If the boolean is false, send the token to your server,
// otherwise your server should have already received the token.
sharedPreferences.edit().putBoolean(QuickstartPreferences.SENT_TOKEN_TO_SERVER, true).apply();
// [END register_for_gcm]
}
} catch (Exception e) {
Log.d(TAG, "Failed to complete token refresh", e);
// If an exception happens while fetching the new token or updating our registration data
// on a third-party server, this ensures that we'll attempt the update at a later time.
sharedPreferences.edit().putBoolean(QuickstartPreferences.SENT_TOKEN_TO_SERVER, false).apply();
}
// Notify UI that registration has completed, so the progress indicator can be hidden.
Intent registrationComplete = new Intent(QuickstartPreferences.REGISTRATION_COMPLETE);
LocalBroadcastManager.getInstance(this).sendBroadcast(registrationComplete);
}
