[BroadcastReceiver(Enabled = true, Exported = true)]
[IntentFilter([Intent.ActionPackageAdded, Intent.ActionPackageReplaced, Intent.ActionPackageRemoved], DataScheme = "package")]
public class APKBroadcastReceiver : BroadcastReceiver
{
    public override void OnReceive(Context? context, Intent? intent)
    {
        Toast.MakeText(context, "APK安装...", ToastLength.Long)?.Show();
    }
}

Android8.0以后版本
Android8.0之后很多静态广播不能用了，想要接收应用安装、覆盖安装和删除的广播，需要动态注册广播。
创建广播接收类。

public class APKBroadcastReceiver : BroadcastReceiver
{
    public override void OnReceive(Context? context, Intent? intent)
    {
        Toast.MakeText(context, "APK安装...", ToastLength.Long)?.Show();
    }
}

在类MainActivity的重写OnCreate方法中添加如下代码。

IntentFilter intentFilter = new IntentFilter();
intentFilter.AddAction(Intent.ActionPackageAdded);
intentFilter.AddAction(Intent.ActionPackageRemoved);
intentFilter.AddAction(Intent.ActionPackageReplaced);
intentFilter.AddAction(Intent.ActionPackageInstall);
intentFilter.AddDataScheme("package");
APKBroadcastReceiver apkBroadcastReceiver = new APKBroadcastReceiver();
RegisterReceiver(apkBroadcastReceiver, intentFilter);
