Question

我想进行推送通知，这是我的代码

    public class MyFirebaseMessagingService extends FirebaseMessagingService {

    @Override
    public void onNewToken(String s) {
        Log.e("NEW_TOKEN", s);
    }

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        Intent intent = new Intent(this, MainActivity.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
        notificationBuilder.setContentTitle("FCM NOTIFICATION");
        notificationBuilder.setContentText(remoteMessage.getNotification().getBody());
        notificationBuilder.setAutoCancel(true);
        notificationBuilder.setSmallIcon((R.mipmap.ic_launcher));
        notificationBuilder.setContentIntent(pendingIntent);
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0, notificationBuilder.build());

    }
}

但是它不起作用，我认为这个令牌问题我已经看到了很多有关获取令牌的问题和答案，但是我在那儿找不到有用的信息。我将不胜感激，谢谢您。

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener( MainActivity.this,  new OnSuccessListener<InstanceIdResult>() {
        @Override
        public void onSuccess(InstanceIdResult instanceIdResult) {
            String newToken = instanceIdResult.getToken();
            Log.e("newToken",newToken);

        }
    });
}

}

尝试这种方式。 1.创建服务

public class YourService extends FirebaseMessagingService {

public static int NOTIFICATION_ID = 1;

@Override
public void onNewToken(String s) {
    super.onNewToken(s);
}

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    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 mNotifyBuilder = new NotificationCompat.Builder(this, "2")
            .setSmallIcon(R.drawable.your_icon)
            .setContentTitle(remoteMessage.getNotification().getTitle())
            .setContentText(remoteMessage.getNotification().getBody())
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    if (NOTIFICATION_ID > 1073741824) {
        NOTIFICATION_ID = 0;
    }
    Objects.requireNonNull(notificationManager).notify(NOTIFICATION_ID++, mNotifyBuilder.build());
}

}

现在将其添加到清单

<service
   android:name=".YourService"
   android:exported="false">
   <intent-filter>
       <action android:name="com.google.firebase.MESSAGING_EVENT" />
   </intent-filter>
</service>

使用Firebase在Android中推送通知获取令牌
