Android通知会同时显示并消失，而不做任何事情

我向android手机发送推送通知。 除了三星Galaxy Note 5之外，几乎所有手机都可以接收和显示通知

手机会显示通知图标并同时启动。 您可以在7秒和22秒后看到此问题：

这是我的应用程序的AndroidMenifest.xml

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <meta-data
        android:name="com.google.firebase.messaging.default_notification_icon"
        android:resource="@drawable/ic_stat_notification" />
    <meta-data
        android:name="com.google.firebase.messaging.default_notification_color"
        android:resource="@color/colorAccent" />
    <meta-data
        android:name="com.google.firebase.messaging.default_notification_channel_id"
        android:value="@string/default_notification_channel_id" />

    <activity
        android:name=".MainActivity"
        android:configChanges="keyboard|keyboardHidden|orientation|orientation|screenSize">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

    <service android:name=".FCMInstanceService">
        <intent-filter>
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
        </intent-filter>
    </service>
    <service
        android:name=".MyFirebaseMessagingService"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>
</application>

您现在不需要两种服务。。。。。 检查此主题：

你不需要这个

<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />

渐变型

implementation 'com.google.firebase:firebase-core:16.0.3'
implementation 'com.google.firebase:firebase-messaging:17.3.0'

请使用MyFirebaseMessagingService服务的代码编辑该问题。@Yasiru Nayanajith我添加了它。您不需要AndroidManifest.xml中的FCMInstanceService服务

implementation 'com.google.firebase:firebase-core:16.0.3'
implementation 'com.google.firebase:firebase-messaging:17.3.0'
