我想做推送通知，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());
}
}
但这不起作用，我认为令牌的问题我已经看到了很多有关获取令牌的问题和答案，但我无法在那里获得有用的信息。我将不胜感激任何答案，提前致谢。
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);
}
});
}
}
试试这个方法。
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中
<service
android:name=".YourService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
