Question

我想在启动时运行我的后台服务，我在Android上使用Xamarin Forms。我按照Rob Gibbens https://github.com/RobGibbens/XamarinFormsBackgrounding的一个很好的例子“LongRunningTaskService”创建了这个服务并且工作得很好，但我在启动时需要它，而不是由UI触发。我在启动时添加了服务，并且在mscorlib.dll启动后立即发生了崩溃。即使删除了所有代码并且除了广播监听器之外没有做任何事情，也会发生崩溃。

这里是广播听众

using Android.App;
using Android.Content;
namespace FormsBackgrounding.Droid
{
    [BroadcastReceiver(Enabled = true)]
    [IntentFilter(new[] { Android.Content.Intent.ActionBootCompleted })]
    public class StartReceiver : BroadcastReceiver
    {
        public override void OnReceive(Context context, Intent intent)
        {
            //if (intent.Action == Intent.ActionBootCompleted)
            //{ 
                //Intent timerIntent = new Intent(context, typeof(LongRunningTaskService));
               //Application.Context.StartService(timerIntent);
            //}
        }
    }
}

这里是清单

<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" package="com.arteksoftware.formsbackgrounding">
    <uses-sdk android:minSdkVersion="16" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <application android:label="FormsBackgrounding">
    <receiver android:name="StartReceiver">
         <intent-filter>
         <action android:name="android.intent.action.BOOT_COMPLETED" />
         </intent-filter>
    </receiver>
    <service android:name=".LongRunningTaskService" ></service>
    </application>
</manifest>

任何人遇到同样的问题？有任何解决方法吗？
