FireBase云消息传递不工作

Question

我正在尝试使用FireBase云消息传递。我正在接收令牌，但它没有从控制台收到任何通知。这是我的舱单：

  <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="careerage.jobseeker.app"
android:hardwareAccelerated="true"
android:versionCode="1"
android:versionName="0.0.1">

<uses-sdk
    android:minSdkVersion="16"
    android:targetSdkVersion="23" />

<supports-screens
    android:anyDensity="true"
    android:largeScreens="true"
    android:normalScreens="true"
    android:resizeable="true"
    android:smallScreens="true"
    android:xlargeScreens="true" />

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<android:uses-permission android:name="android.permission.READ_PHONE_STATE" />
<android:uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

<application
    android:hardwareAccelerated="true"
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:supportsRtl="true">
    <activity
        android:name=".MainActivity"
        android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale"
        android:label="@string/activity_name"
        android:launchMode="singleTop"
        android:theme="@android:style/Theme.DeviceDefault.NoActionBar"
        android:windowSoftInputMode="adjustResize">
        <intent-filter android:label="@string/launcher_name">
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <service
        android:name=".TokenService">
        <intent-filter>
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
        </intent-filter>
    </service>
    <service
        android:name=".NotificationService">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT"/>
        </intent-filter>
    </service>
</application>

我的代码与示例中的代码几乎相同：

public class NotificationService extends FirebaseMessagingService {

private void sendNotification(String messagebody) {
    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 notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.icon)
            .setContentTitle("Notified")
            .setContentText(messagebody)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

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

    notificationManager.notify(0 , notificationBuilder.build());
}

private void sendSnackbar(String messagebody)
{
    Toast.makeText(this,"Notified",Toast.LENGTH_LONG).show();
}

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    Toast.makeText(this,"Message Received",Toast.LENGTH_LONG).show();

        Log.d("Notification Received",remoteMessage.getNotification().getBody());

        sendNotification(remoteMessage.getNotification().getBody());
    sendSnackbar(remoteMessage.getNotification().getBody());
}

}

我在这里检查了一个问题，Firebase云消息通知未被设备接收，但仍然无法工作。

您需要使用下面的整个软件包名称更改服务，

<service
    android:name="your.package.name.TokenService">
    <intent-filter>
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
    </intent-filter>
</service>
<service
    android:name="your.package.name.NotificationService">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT"/>
    </intent-filter>
</service>

如果它不工作，请让我知道。

尝试使用服务api调用发送消息。它将为您提供响应代码和响应json，这可能有助于您了解无法使用FCM的原因。

此处应答的服务呼叫使用-应用程序处于后台时未调用Firebase onMessageReceived
