我正在尝试使用自定义通知音。应用程序运行时音调正常,但应用程序在后台时播放默认音调。当应用程序未处于活动状态时收到通知消息时,振动也不起作用

我试过如下:

我的Messenging Service类。

public class MyFirebaseMessagingService extends FirebaseMessagingService{

private static final String TAG = "MyFirebaseMsgService";
Utilities utils = new Utilities();
Notification notification;
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    if (remoteMessage.getData() != null) {
        sendNotification(remoteMessage.getData().get("message"));
        Log.e(TAG,remoteMessage.getData().get("message"));
    }else{
        utils.print(TAG,"FCM Notification failed");
    }
}
private void sendNotification(String messageBody) {
    long[] v = {500,1000};

    if (!isAppIsInBackground(getApplicationContext())) {

        utils.print(TAG,"foreground");
        Log.e(TAG,"Notifcation"+messageBody);
            Intent intent = new Intent(this, MainActivity.class);
            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            intent.putExtra("push", true);
            PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
                    PendingIntent.FLAG_ONE_SHOT);


            NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                    .setContentTitle(getString(R.string.app_name))
                    .setContentText(messageBody)
                    .setAutoCancel(false)
                    .setVibrate(v)
                    .setContentIntent(pendingIntent);

            notificationBuilder.setSmallIcon(getNotificationIcon(notificationBuilder), 1);

        notification = notificationBuilder.build();
        notification.sound=Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.alert_tone);
        notification.defaults=Notification.DEFAULT_LIGHTS | Notification.DEFAULT_VIBRATE;

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

            notificationManager.notify(0, notification);
    }
    else{

您可以通过发送通知将推送通知发送到您的应用,以便在您的应用关闭时根据某些参数发送消息。

在完成此操作之前,请先确保您的项目已在Fire base中添加:否则,请在项目的app文件夹中使用包名称,指纹和google_services.json文件在fire base中添加项目。

Fire base Cloud Messaging

它会将通知推送到您的应用程序,如果已关闭则允许用户通过按下通知打开应用程序,如果您想向用户显示通知以指向同一帐户的其他应用程序,则应用程序将在使用这两个代码都会发生:

创建第一个类MyFirebaseMessagingService

public class MyFirebaseMessagingService extends FirebaseMessagingService {

private static final String NOTIFICATION_ID_EXTRA = "notificationId";
private static final String IMAGE_URL_EXTRA = "imageUrl";
private static final String ADMIN_CHANNEL_ID ="admin_channel";
private NotificationManager notificationManager;


@Override
public void onMessageReceived(RemoteMessage remoteMessage) {

    if (remoteMessage.getData().size()>0){

        Intent notificationIntent = new Intent(Intent.ACTION_VIEW);
        notificationIntent.setData(Uri.parse(remoteMessage.getData().get("applink")));
        PendingIntent pi = PendingIntent.getActivity(this, 0, notificationIntent, 0);
        notificationIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        final PendingIntent pendingIntent = PendingIntent.getActivity(this,
                0 /* Request code */, notificationIntent,
                PendingIntent.FLAG_ONE_SHOT);

        int notificationId = new Random().nextInt(60000);
        Bitmap bitmap = getBitmapfromUrl(remoteMessage.getData().get("imageurl"));

        Intent likeIntent = new Intent(this,LikeService.class);
        likeIntent.putExtra(NOTIFICATION_ID_EXTRA,notificationId);
        likeIntent.putExtra(IMAGE_URL_EXTRA,remoteMessage.getData().get("message"));
        PendingIntent likePendingIntent = PendingIntent.getService(this,
                notificationId+1,likeIntent, PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

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

        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {

            setupChannels();

        }

        NotificationCompat.Builder notificationBuilder =
                new NotificationCompat.Builder(this, ADMIN_CHANNEL_ID)
                        .setLargeIcon(bitmap)
                        .setSmallIcon(R.mipmap.ic_launcher)
                        .setContentTitle(remoteMessage.getData().get("title"))
                        .setStyle(new NotificationCompat.BigPictureStyle()
                                .setSummaryText(remoteMessage.getData().get("message"))
                                .bigPicture(bitmap))/*Notification with Image*/
                        .setContentText(remoteMessage.getData().get("message"))
                        .setAutoCancel(true)
                        .setSound(defaultSoundUri)
                        .addAction(R.drawable.icon,
                                getString(R.string.notification_add_to_cart_button),likePendingIntent)
                        .setContentIntent(pendingIntent);

        notificationManager.notify(notificationId, notificationBuilder.build());


    }

}


@RequiresApi(api = Build.VERSION_CODES.O)
private void setupChannels(){
    CharSequence adminChannelName = getString(R.string.notifications_admin_channel_name);
    String adminChannelDescription = getString(R.string.notifications_admin_channel_description);

    NotificationChannel adminChannel;
    adminChannel = new NotificationChannel(ADMIN_CHANNEL_ID, adminChannelName, NotificationManager.IMPORTANCE_LOW);
    adminChannel.setDescription(adminChannelDescription);
    adminChannel.enableLights(true);
    adminChannel.setLightColor(Color.RED);
    adminChannel.enableVibration(true);
    if (notificationManager != null) {
        notificationManager.createNotificationChannel(adminChannel);
    }
}



public Bitmap getBitmapfromUrl(String imageUrl) {
    try {
        URL url = new URL(imageUrl);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        return BitmapFactory.decodeStream(input);

    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
}


    }

创建另一个类FirebaseIDService以获取fire base的实例ID服务

public class FirebaseIDService extends FirebaseInstanceIdService {


public static final String FIREBASE_TOKEN = "firebase token";

@Override
public void onTokenRefresh() {
    super.onTokenRefresh();

    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    SharedPreferences preferences =
            PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
    preferences.edit().putString(FIREBASE_TOKEN, refreshedToken).apply();

}

使类名称LikeService

public class LikeService extends Service {

private static final String NOTIFICATION_ID_EXTRA = "notificationId";
private static final String IMAGE_URL_EXTRA = "imageUrl";
@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}
    }

使用firebase支持Oreo的通知不要忘记创建频道,并在第一个启动器活动中初始化此频道。

在你的项目的第一个启动器活动的创建包括这些渠道;

   String channelId = "1";
    String channel2 = "2";

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

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        NotificationChannel notificationChannel = new NotificationChannel(channelId,
                "Channel 1", NotificationManager.IMPORTANCE_HIGH);

        notificationChannel.setDescription("This is BNT");
        notificationChannel.setLightColor(Color.RED);
        notificationChannel.enableVibration(true);
        notificationChannel.setShowBadge(true);
        notificationManager.createNotificationChannel(notificationChannel);

        NotificationChannel notificationChannel2 = new NotificationChannel(channel2,
                "Channel 2",NotificationManager.IMPORTANCE_MIN);

        notificationChannel.setDescription("This is bTV");
        notificationChannel.setLightColor(Color.RED);
        notificationChannel.enableVibration(true);
        notificationChannel.setShowBadge(true);
        notificationManager.createNotificationChannel(notificationChannel2);

    }

现在,您必须将Firebase服务类放在Mainfest的应用程序标记下:

      <service android:name=".activities.services.MyFirebaseMessagingService"
        android:permission="com.google.android.c2dm.permission.SEND">
        <intent-filter>

            <action android:name="com.google.firebase.MESSAGING_EVENT"/>
            <action android:name="com.google.android.c2dm.intent.RECEIVE"/>

        </intent-filter>

    </service>

    <service android:name=".activities.services.FirebaseIDService">
        <intent-filter>
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
        </intent-filter>
    </service>

现在在您的设备上运行您的应用程序,然后使用fire base进行推送通知,确保您的代码正确集成,然后运行app:并转到基本云消息:

根据您的应用将数据放入照片中:关闭时:

如果您的应用程序正在使用,那么您的数据将提前显示,其相关帐户的促销应用程序的数据,请在此处使用其他帐户应用程序,

确保你的密钥应该像上面的类一样在MyFirebaseMessagingService中接收onMessagede

此外,如果您需要任何教程,请使用此方法
