私は、Android Studioを使用してAndroidアプリでGoogleの通知を使用しようとした、よく私は、登録サービスのAndroid StudioのGCM
public class GCMRegistrationIntentService extends IntentService
{
public static final String REGISTRATION_SUCCESS = "RegistrationSuccess";
public static final String REGISTRATION_ERROR = "RegistrationError";
public GCMRegistrationIntentService() {
super("");
}
@Override
protected void onHandleIntent(Intent intent) {
registerGCM();
}
private void registerGCM() {
Intent registrationComplete = null;
String token = null;
try {
InstanceID instanceID = InstanceID.getInstance(getApplicationContext());
token = instanceID.getToken(getString(R.string.gcm_defaultSenderId), GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
Log.w("GCMRegIntentService", "token:" + token);
//notify to UI that registration complete success
registrationComplete = new Intent(REGISTRATION_SUCCESS);
registrationComplete.putExtra("token", token);
} catch (Exception e) {
Log.w("GCMRegIntentService", "Registration error");
registrationComplete = new Intent(REGISTRATION_ERROR);
}
//Send broadcast
LocalBroadcastManager.getInstance(this).sendBroadcast(registrationComplete);
}
}
にこのクラスを持っていますが、私はこの方法registerGCM（呼び出そう）それは私にこのことを示していエラー
