颤振:计划通知不起作用

Question

我正在使用Flutter开发一个应用程序。

显示通知 I 一个正在使用flutter_local_notifications包。

我收到通知，但计划通知不起作用。

这里提出了类似的问题 如何在 Flutter 中安排通知？，但我的接收器已经在 application 标签内。

这是我的清单

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.folk.gayatrimonitor">
<!-- The INTERNET permission is required for development. Specifically,
     flutter needs it to communicate with the running application
     to allow setting breakpoints, to provide hot reload, etc.
-->
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<!-- io.flutter.app.FlutterApplication is an android.app.Application that
     calls FlutterMain.startInitialization(this); in its onCreate method.
     In most cases you can leave this as-is, but you if you want to provide
     additional functionality it is fine to subclass or reimplement
     FlutterApplication and put your custom class here. -->
<application
    android:name="io.flutter.app.FlutterApplication"
    android:label="gayatri_monitor"
    android:icon="@mipmap/ic_launcher">
    <receiver android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationReceiver" />
    <receiver android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationBootReceiver">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED"></action>
        </intent-filter>
    </receiver>
    <activity
        android:name=".MainActivity"
        android:launchMode="singleTop"
        android:theme="@style/LaunchTheme"
        android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density"
        android:hardwareAccelerated="true"
        android:windowSoftInputMode="adjustResize">
        <!-- This keeps the window background of the activity showing
             until Flutter renders its first frame. It can be removed if
             there is no splash screen (such as the default splash screen
             defined in @style/LaunchTheme). -->
        <meta-data
            android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
            android:value="true" />
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>
</application>

Answer 1

在

清单的内部应用程序中添加此内容可能会解决您的问题

   <service          android:name="com.folk.localnotifications.services.LocalNotificationsService"
 android:exported="false" />

请记住：com.folk仅用于此项目。对于其他项目，请转到清单，查看包名称并进行相应的编辑。

我遇到了同样的问题，但无法在网上找到解决方案，但是，后来我确实弄清楚了运行flutter clean然后flutter run似乎为我做了这个技巧。

您必须基本上清理您的构建并再次重建它。希望有帮助。

Answer 3

我遇到了同样的问题，我通过为我发布的每个 android 通知创建一个单独的通知通道来解决它，即使它们具有相同的优先级。

就我而言，我只是在initState()中添加了以下内容

var initializationSettingsAndroid =
        AndroidInitializationSettings('@mipmap/ic_launcher');
        var initializationSettingsIOS = IOSInitializationSettings();
        var initializationSettings = InitializationSettings(
            android: initializationSettingsAndroid, iOS: initializationSettingsIOS);
        flutterLocalNotificationsPlugin.initialize(
          initializationSettings,
        );
