私は私のアプリから参照すべてがあります白い画面。そして、私が設定をデバッグに戻すとすぐに、すべてがうまくいきます。

GUIのかなりの部分を変更する前の数日前、すべてが正常に機能していました。問題は、例外メッセージが何を意味するのか分かりません。 StateLockedとは何ですか？

MainActivity.cs：

[Activity(Label = "enio.TrackR", Icon = "@drawable/icon", Theme = "@style/MainTheme", MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)] 
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity 
{ 
    protected override void OnCreate(Bundle bundle) 
    { 
     TabLayoutResource = Resource.Layout.Tabbar; 
     ToolbarResource = Resource.Layout.Toolbar; 

     base.OnCreate(bundle); 

     global::Xamarin.Forms.Forms.Init(this, bundle); 
     LoadApplication(new App()); 
    } 
    protected override void OnStart() 
    { 
     base.OnStart(); 
     StartService(new Intent(this, typeof(LocationService))); 

    } 
} 

Answer 1

私はあなたが

へ

StartService(new Intent(this, typeof(LocationService))); 

を変更する必要があると信じて、私は私のコードのいくつかのより多くの部分の下に追加したコメントから提案されているよう

Intent serviceIntent = new Intent(this, typeof(LocationActivity)); 
context.StartActivity(serviceIntent); 

Answer 2

誰かg Androidプロジェクトプロパティのリンクオプションを「Sdkとユーザアセンブリ」から「Sdkアセンブリのみ」に変更するアドバイスをお願いします。これで問題は解決し、アプリを起動してプレイストアにデプロイすることができました。
