cordova 插件中的本机通知 android 代码 java class

Question

我对 cordova 有所了解，现在我正在我的插件中实现通知 class。

我使用下面的 android 代码在我的 java class 中创建了通知。我已经导入了所有与通知相关的包。但是我收到通知异常，无法收到通知

NotificationManager notificationManager = (NotificationManager)this.getSystemService(getApplicationContext().NOTIFICATION_SERVICE);
    Notification notification=new Notification.Builder(getApplicationContext())
    .setWhen(System.currentTimeMillis())
    .setContentTitle("Welcome")
    .setTicker("Click here to see the offers...")
    .setContentText("Click here to see the offers...")
    //.setSmallIcon(1)
    .setAutoCancel(true)
    .build();

    notificationManager.notify(info, notification);

我得到的异常是

NotificationService(802): Not posting notification with icon==0:     Notification(pri=0 icon=0 contentView=com.ionicframework.dummy292686/0x1090085 vibrate=null sound=null defaults=0x0 flags=0x10 when=1439564895752 ledARGB=0x0 contentIntent=N deleteIntent=N contentTitle=7 contentText=31 originalPackageName=N originalUserId=0 tickerText=31 kind=[null])

有人可以建议在 cordova 插件中编写通知逻辑吗 java class？

Answer 1

我相信你至少需要提供一个小图标。

取消注释 .setSmallIcon(1) 并将 1 替换为要在通知中用作图标的可绘制对象的资源 ID。

Answer 2

最后，我在构建通知对象时做了一些更改，它对我有用。

try{
        Log.i(TAG, "In try block of notification");
        Intent intent = new Intent(this, MainActivity.class);
        PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);
        Notification notification = new Notification.Builder(this)
        .setTicker("My Company")
        .setContentTitle("Welcome")
        .setContentText("Click here to see offers...")
        .setSmallIcon(R.drawable.icon)
        .setContentIntent(pIntent).getNotification();
        notification.flags=Notification.FLAG_AUTO_CANCEL;
        NotificationManager notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
        notificationManager.notify(0, notification);
    }catch(Exception e){
        Log.e(TAG, "In catch block of notification:"+e);
    }
