Question

我正在开发一个 Android 应用程序，它使用 FCM 向应用程序推送通知。高达 API 29(android Q/10) 后台通知运行良好，但在 api 29 以上它不显示我用于通知的图标。此外，当 App 处于前台时，它不会在任何 android 版本中显示图标。它只是显示我提到的颜色。

我尝试的所有内容如下代码：

Firebase 消息服务类

public class NotificationService extends com.google.firebase.messaging.FirebaseMessagingService {
int requestId = 1;

@Override
public void onMessageReceived(@NonNull RemoteMessage remoteMessage) {
    receiveNotification(remoteMessage);
}

private void receiveNotification(RemoteMessage remoteMessage) {
    Intent intent = new Intent(this, UserNameActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, requestId, intent, PendingIntent.FLAG_ONE_SHOT);
    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);


    Notification notification = new NotificationCompat.Builder(this, FCM_CHANNEL_ID)
            .setSmallIcon(R.drawable.notification_icon)
            .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.notification_icon))
            .setContentTitle(remoteMessage.getNotification().getTitle())
            .setContentText(remoteMessage.getNotification().getBody())
            .setAutoCancel(true)
            .setColor(getResources().getColor(R.color.colorPrimaryDark))
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent)
            .build();
    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(requestId, notification);
}


@Override
public void onNewToken(@NonNull String s) {
}}

应用类

public class App extends Application {

public static final String FCM_CHANNEL_ID = "FCM_CHANNEL_ID";

@Override
public void onCreate() {
    super.onCreate();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel notificationChannel = new NotificationChannel(FCM_CHANNEL_ID, "FCM_CHANNEL", NotificationManager.IMPORTANCE_DEFAULT);

        NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        manager.createNotificationChannel(notificationChannel);
    }
}}

清单文件：

package="com.example.marvel">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    android:networkSecurityConfig="@xml/network"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    android:usesCleartextTraffic="true">
    <activity android:name=".activity.UserNameActivity" />
    <activity android:name=".activity.SplashActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <service
        android:name=".services.NotificationService"
        android:exported="false">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>
</application>

我不知道我到底错过了什么。如果有人可以帮助我，请评论或回复此帖子。

先谢谢你！
