中生成此處應在客戶註冊時生成GCM ID。但拋出錯誤。GCM ID未在android
public void sendGCMKey() {
try {
FirebaseApp.initializeApp(this);
MyInstanceIDListenerService m = new MyInstanceIDListenerService(this, schoolId);
m.onTokenRefresh();
SharedPreferenceSingleton.getInstance().writeStringPreference("isFCMTokenGenerated","YES");
} catch (Exception e) {
e.printStackTrace();
}
}
這是服務類代碼
@Override
public void onTokenRefresh() {
// Get updated InstanceID token.
FirebaseApp.initializeApp(context); // Newly added 20/9/2017
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
// TODO: Implement this method to send any registration to your app's servers.
sendRegistrationToServer(refreshedToken);
}
private void sendRegistrationToServer(String refreshedToken) {
Log.e("Refreshed Token ::",refreshedToken);
try {
SharedPreferenceSingleton.getInstance().init(context);
SharedPreferenceSingleton.getInstance().writeStringPreference(ApplicationConstants.GCM_ID_KEY, refreshedToken);
int appVersion = getAppVersion(context);
SharedPreferenceSingleton.getInstance().writeIntPreference(ApplicationConstants.GCM_VERSION_KEY, appVersion);
SharedPreferenceSingleton.getInstance().init(context);
String mobileNumber = SharedPreferenceSingleton.getInstance().getStringPreference(ApplicationConstants.MOBILE_KEY);
JSONObject jsonObject = new JSONObject();
jsonObject.put(RegistrationContracts.MOBILE_KEY, mobileNumber);
jsonObject.put(RegistrationContracts.SCHOOL_ID_KEY, schoolId);
jsonObject.put(BroadcastContract.TYPE_KEY,BroadcastContract.TEACHER_TYPE_KEY_);
jsonObject.put(RegistrationContracts.GCM_KEY, refreshedToken);
AsyncWorkerEncrypted asyncGCMWorker = new AsyncWorkerEncrypted(context);
asyncGCMWorker.delegate = MyInstanceIDListenerService.this;
asyncGCMWorker.execute(ServerConnector.SEND_GCM_ID, jsonObject.toString(), RequestConstants.POST_REQUEST, RequestConstants.HEADER_YES, RequestConstants.GCM_SEND_ID);
} catch (Exception e){
e.printStackTrace();
}
它拋出錯誤：
java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process com.xxx.cbcbc Make sure to call FirebaseApp.initializeApp(Context) first.
誰能幫我找出這個問題？
什麼是描述了'MyInstanceIDListenerService M =新MyInstanceIDListenerService（此，schoolId ）;'？你不知道，如何使用android服務？用清單聲明它，然後等待。令牌生成異步，並可能更改 –
，並且還可以在任何地方移除該行'FirebaseApp.initializeApp（context）;'。切勿手動調用它，除非您正在擴展我的應用程序類 –
。它仍然沒有解決這個問題 – deva11
