Question

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，但是无法使其正常工作。任何帮助将不胜感激。

的AndroidManifest.xml

<?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>

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自动显示清单，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。
