未生成 FCM 令牌 ID

Question

我没有收到FCM令牌。

在我的登录屏幕上，我正在调用这个

startService(new Intent(this, FetchNewRefreshToken.class));
startService(new Intent(this, ContCreateTokenService.class));

我的清单

<service android:name=".MyFirebaseMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
<service android:name=".FirebaseIdService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
<service android:name=".ContCreateTokenService" />
<service android:name=".FetchNewRefreshToken" />

public class ContCreateTokenService extends Service {
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Intent serviceIntent = new Intent(this, MyFirebaseMessagingService.class);
startService(serviceIntent);
return START_REDELIVER_INTENT;
}
}

public class FetchNewRefreshToken extends IntentService {
/**
* Creates an IntentService.  Invoked by your subclass's constructor.
*
* @param name Used to name the worker thread, important only for debugging.
*/
public static final String TAG = FetchNewRefreshToken.class.getSimpleName();

public FetchNewRefreshToken() {
super(TAG);
}
@Override
protected void onHandleIntent(Intent intent) {
try {
// Resets Instance ID and revokes all tokens.
FirebaseInstanceId.getInstance().deleteInstanceId();

// Now manually call onTokenRefresh()
Log.d(TAG, "Getting new token");
String token= FirebaseInstanceId.getInstance().getToken();
final Intent intents = new Intent("tokenReceiver");
// You can also include some extra data.
final LocalBroadcastManager broadcastManager = LocalBroadcastManager.getInstance(this);
intents.putExtra("token", token);
broadcastManager.sendBroadcast(intents);
} catch (Exception e) {
e.printStackTrace();
}
}
}

public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "FCM Service";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// TODO: Handle FCM messages here.
// If the application is in the foreground handle both data and notification messages here.
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated.
Log.d(TAG, "From: " + remoteMessage.getFrom());
Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {

Log.d(TAG, "Message data payload: " + remoteMessage.getData());
sendNotification("text");
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
}
}
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 , intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_notifications_black_24dp)
.setContentTitle("FCM Message")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
}

我的主要活动类

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LocalBroadcastManager.getInstance(this).registerReceiver(tokenReceiver,
new IntentFilter("tokenReceiver"));
}
BroadcastReceiver tokenReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String token = intent.getStringExtra("token");
//Log.d("token",token);
// String token=FirebaseInstanceId.getInstance().getToken();
if(token != null)
{
//send token to your server or what you want to do
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
Log.d("token",token);
Firebase reference1 = new Firebase("https://fuudful-1a15c.firebaseio.com/users/" +user.getUid());
Map<String, String> map = new HashMap<String, String>();
map.put("registrationtoken", token);
reference1.push().setValue(map);
}
}
};

我没有收到令牌，通知也没有生成，并且数据库中没有插入。

请有人帮我解决这个问题吗？

检查GooglePlayserviceVersion是否安装了旧版本，那么它将对Firebase产生问题

检查谷歌播放服务版本的方法

private boolean checkPlayServices() {
GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance();
int resultCode = apiAvailability.isGooglePlayServicesAvailable(this);
if (resultCode != ConnectionResult.SUCCESS) {
goahead = false;
if (apiAvailability.isUserResolvableError(resultCode)) {
dialog = apiAvailability.getErrorDialog(this, resultCode, PLAY_SERVICES_RESOLUTION_REQUEST);
dialog.setCancelable(false);
dialog.setCanceledOnTouchOutside(false);
dialog.show();
} else {
Log.i("Demo App", "This device is not supported.");
AlertDialog.Builder dialog_app = new AlertDialog.Builder(SplashActivity.this);
dialog_app.setTitle("Error");
dialog_app.setMessage("This device is not supported..");
dialog_app.setCancelable(false);
dialog_app.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
finish();
}
});
dialog_app.show();
}
return false;
}
return true;
}

如果谷歌播放服务是旧的，那么此方法将显示更新对话框，否则它返回 true，您可以调用服务。

检查播放服务版本

if(checkPlayServices())
{
Intent intent = new Intent(this, RegistrationIntentService.class);
startService(intent);
}

CustomFirebaseInstanceIDService.class： Service Class for Refesh Token

public class CustomFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG = CustomFirebaseInstanceIDService.class.getSimpleName();
@Override
public void onCreate() {
super.onCreate();
}
@Override
public void onTokenRefresh() {
Intent intent = new Intent(this, RegistrationIntentService.class);
startService(intent);
}
}

用于获取 FCM 令牌的服务类：注册意图服务.class

public class RegistrationIntentService extends IntentService {
// abbreviated tag name
private static final String TAG = RegistrationIntentService.class.getSimpleName();
public RegistrationIntentService() {
super(TAG);
}
String token;
@Override
protected void onHandleIntent(Intent intent) {
// Make a call to Instance API
FirebaseInstanceId instanceID = FirebaseInstanceId.getInstance();

//String senderId = getResources().getString(R.string.gcm_defaultSenderId);
// request token that will be used by the server to send push notifications
token = instanceID.getToken();
Log.d(TAG, "FCM Registration Token: " + token);
}
}

在清单文件中定义服务

<service android:name=".notification.CustomFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
<service
android:name=".notification.RegistrationIntentService"
android:exported="false" />

与其制作意图服务，不如尝试使用自己的服务来生成令牌。将其存储到您的首选项中，然后随时使用。

public class TokenService extends FirebaseInstanceIdService {
@Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.w("notification", refreshedToken);
//store token into preference
}
}

将以下行放入您的 AndroidManifest.xml 文件中：

<service
android:name=".TokenService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
