现在FirebaseInstanceId
也已经被弃用。
我们现在需要使用FirebaseMessaging.getInstance().token
示例代码
FirebaseMessaging.getInstance().token.addOnCompleteListener {
if(it.isComplete){
firebaseToken = it.result.toString()
Util.printLog(firebaseToken)
}
}
是的,FirebaseInstanceIdService
已被弃用
来自文档:- 已经弃用了这个类。
改用在FirebaseMessagingService
中覆盖onNewToken
。 一旦实现了这个,就可以安全地删除此服务。
无需使用FirebaseInstanceIdService
服务获取FCM令牌,您可以安全地将其删除。
现在,我们需要@Override onNewToken
在FirebaseMessagingService
中获得Token
示例代码
public class MyFirebaseMessagingService extends FirebaseMessagingService {
@Override
public void onNewToken(String s) {
Log.e("NEW_TOKEN", s);
}
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Map<String, String> params = remoteMessage.getData();
JSONObject object = new JSONObject(params);
Log.e("JSON_OBJECT", object.toString());
String NOTIFICATION_CHANNEL_ID = "Nilesh_channel";
long pattern[] = {0, 1000, 500, 1000};
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "Your Notifications",
NotificationManager.IMPORTANCE_HIGH);
notificationChannel.setDescription("");
notificationChannel.enableLights(true);
notificationChannel.setLightColor(Color.RED);
notificationChannel.setVibrationPattern(pattern);
notificationChannel.enableVibration(true);
mNotificationManager.createNotificationChannel(notificationChannel);
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = mNotificationManager.getNotificationChannel(NOTIFICATION_CHANNEL_ID);
channel.canBypassDnd();
}
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);
notificationBuilder.setAutoCancel(true)
.setColor(ContextCompat.getColor(this, R.color.colorAccent))
.setContentTitle(getString(R.string.app_name))
.setContentText(remoteMessage.getNotification().getBody())
.setDefaults(Notification.DEFAULT_ALL)
.setWhen(System.currentTimeMillis())
.setSmallIcon(R.drawable.ic_launcher_background)
.setAutoCancel(true);
mNotificationManager.notify(1000, notificationBuilder.build());
}
}
#编辑
您需要像这样在清单文件中注册您的FirebaseMessagingService
<service
android:name=".MyFirebaseMessagingService"
android:stopWithTask="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
#如何在您的Activity中获取令牌
.getToken();
已弃用,如果您需要在Activity中获取令牌,请使用getInstanceId()
现在我们需要使用getInstanceId()
来生成令牌
getInstanceId()
返回此Firebase项目的ID和自动生成令牌
如果尚不存在实例ID,则会生成一个实例ID,该ID开始定期发送信息到Firebase后端。
返回值
- 任务,您可以使用它通过
InstanceIdResult
查看结果,其中包含ID
和token
示例代码
FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener( MyActivity.this, new OnSuccessListener<InstanceIdResult>() {
@Override
public void onSuccess(InstanceIdResult instanceIdResult) {
String newToken = instanceIdResult.getToken();
Log.e("newToken",newToken);
}
});
##编辑2
这里是Kotlin的可运行代码。
class MyFirebaseMessagingService : FirebaseMessagingService() {
override fun onNewToken(p0: String?) {
}
override fun onMessageReceived(remoteMessage: RemoteMessage?) {
val notificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val NOTIFICATION_CHANNEL_ID = "Nilesh_channel"
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val notificationChannel = NotificationChannel(NOTIFICATION_CHANNEL_ID, "Your Notifications", NotificationManager.IMPORTANCE_HIGH)
notificationChannel.description = "Description"
notificationChannel.enableLights(true)
notificationChannel.lightColor = Color.RED
notificationChannel.vibrationPattern = longArrayOf(0, 1000, 500, 1000)
notificationChannel.enableVibration(true)
notificationManager.createNotificationChannel(notificationChannel)
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channel = notificationManager.getNotificationChannel(NOTIFICATION_CHANNEL_ID)
channel.canBypassDnd()
}
val notificationBuilder = NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID)
notificationBuilder.setAutoCancel(true)
.setColor(ContextCompat.getColor(this, R.color.colorAccent))
.setContentTitle(getString(R.string.app_name))
.setContentText(remoteMessage!!.getNotification()!!.getBody())
.setDefaults(Notification.DEFAULT_ALL)
.setWhen(System.currentTimeMillis())
.setSmallIcon(R.drawable.ic_launcher_background)
.setAutoCancel(true)
notificationManager.notify(1000, notificationBuilder.build())
}
}
super.onNewToken(s);
吗?(我在https://firebase.google.com/docs/cloud-messaging/android/client上没有看到它被调用。) - ban-geoengineering
