monodroid接收器PACKAGE_REMOVED java.lang.ClassNotFoundException

我正在使用monodroid . 捕获PACKAGE_REMOVED操作时,我一直收到java.lang.ClassNotFoundException错误 . 我已经在stackflow和其他网站上搜索并尝试了很多东西,但无法使其正常工作 . 任何帮助,将不胜感激 .

AndroidManifest.xml中

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:installLocation="internalOnly">
<uses-sdk android:targetSdkVersion="10" />
<uses-permission android:name="android.permission.INTERNET" />
<application android:icon="@drawable/Icon" android:label="App Store">
<receiver android:name=".PackageChangeReceiver" android:exported="true" android:enabled="true">
  <intent-filter android:priority="999">
    <action android:name="android.intent.action.PACKAGE_REMOVED" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:scheme="package" />
  </intent-filter>
</receiver>
</application>
</manifest>

广播接收器(PackageChangeReceiver.cs)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Android.App;
using Android.Content;
using Android.OS;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using System.Net;
using System.IO;
using Android.Util;

namespace AppStore
{
[BroadcastReceiver]
public class PackageChangeReceiver : BroadcastReceiver
{
    public override void OnReceive(Context context, Intent intent)
    {
        if ("android.intent.action.PACKAGE_REMOVED".Equals(intent.Action))
        {
            Boolean replacing = intent.GetBooleanExtra(Intent.ExtraReplacing, false);
            if (replacing)
            {
                //do nothing because will be reinstalled again
            }
            else
            {
                Intent pushIntent = new Intent(context, typeof(UpdatesService));
                pushIntent.PutExtra("appname", intent.Data.ToString());
                context.StartService(pushIntent);  
            }
        }
    }
}
}

    我直接与Xamarin(Monodroid)联系 . 我的错误似乎是手动编辑清单 . 我做了网络搜索,寻找解决方案,并在清单中添加了条目 . 但是,这并没有与monodroid代码连接 . 由于monodroid autobuild清单,你必须使用广播接收器上的属性,如下所示:

    [BroadcastReceiver] 
    [IntentFilter(new string[] { Intent.ActionPackageRemoved }, Priority = (int)IntentFilterPriority.HighPriority, DataScheme="package")] 
    public class PackageChangeReceiver : BroadcastReceiver 
    {
    

    希望这有助于其他人 .
