在Android设备上实现FCM(Firebase Cloud Messaging)推送通知,即使在游戏被杀的情况下也能工作,可以通过以下步骤实现:
implementation 'com.google.firebase:firebase-messaging:22.0.0'
<service
android:name=".MyFirebaseMessagingService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
public class MyFirebaseMessagingService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// 处理接收到的消息,并显示通知
}
}
public class MyFirebaseMessagingService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// 处理接收到的消息,并显示通知
if (remoteMessage.getNotification() != null) {
String title = remoteMessage.getNotification().getTitle();
String body = remoteMessage.getNotification().getBody();
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "channel_id")
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle(title)
.setContentText(body)
.setPriority(NotificationCompat.PRIORITY_DEFAULT);
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(0, builder.build());
}
}
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel("channel_id", "Channel Name", NotificationManager.IMPORTANCE_DEFAULT);
NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);
}
FirebaseMessaging.getInstance().getToken()
.addOnCompleteListener(task -> {
if (!task.isSuccessful()) {
Log.w("FCM Token", "Fetching FCM registration token failed", task.getException());
return;
}
// 获取设备令牌
String token = task.getResult();
// 将设备令牌发送到后端服务器进行注册
// ...
});
以上步骤可以帮助你在Android设备上实现FCM推送通知,即使在游戏被杀的情况下也能正常工作。请注意,这只是一个基本的实现示例,你可以根据自己的需求进行定制和扩展。
