Android应用程序无法部署到虚拟设备

Question

背景:
我正在用Xamarin.Forms创建一个内部移动应用程序，通过WebLink分发。我已经在Android和iOS上运行了几天了，但请求的是推送通知。我们决定和Pushwoosh一起提供这项服务。

我已经从pushwoosh复制了示例代码，并用我们的包名和密钥对其进行了修改，但由于某种原因，我得到了错误:
应用程序无法启动。确保应用程序已安装到目标设备上，并且具有可启动的activity（MainLauncher=true）。
此外，请检查Build->Configuration Manager，以确保已将此项目设置为针对此配置进行部署。

我还应该注意到Pushwoosh使用了GCM，所以它也可能与此相关。

我尝试的内容:
1。我的第一步显然是检查配置管理器。它确实被设置为部署，并且被设置为编译x86（提到的其他问题的一些其他答案已经修复）
2。我确认我的mainactivity.cs文件中的activity是用mainlauncher=true独立设置的。
3。正如其他问题/答案所推荐的，我已经从虚拟Android中删除了该应用程序。（实际上我完全重置了虚拟设备）。
4。正如某些特定于GCM的QA中所提到的，我已经将我的包名全部改为小写。

我的相关代码:

[Activity(Label = "mobile", Icon = "@drawable/icon", MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
[IntentFilter(new string[] { "company.MESSAGE" }, Categories = new string[] { "android.intent.category.DEFAULT" })]
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsApplicationActivity
{
    LocalMessageBroadcastReceiver mMessageReceiver;
    LocalRegisterBroadcastReceiver mRegisterReceiver;

    bool mBroadcastPush = true;

    protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);

        mMessageReceiver = new LocalMessageBroadcastReceiver();
        mMessageReceiver.activity = this;

        mRegisterReceiver = new LocalRegisterBroadcastReceiver();
        mRegisterReceiver.activity = this;
        registerReceivers();

        PushManager manager = PushManager.GetInstance(this);
        manager.OnStartup(this);

        //Register for push!
        manager.RegisterForPushNotifications();

        checkMessage(Intent);

        global::Xamarin.Forms.Forms.Init(this, bundle);
        LoadApplication(new App());
    }

    protected override void OnNewIntent(Intent intent)

我承认我是android开发的新手（但不是.NET或C#)，所以这可能是比较明显的事情，但我很茫然。我已经看过了我能找到的与此相关的每一个问题，没有一个解决方案有用。有人能看出我做错了什么吗？

Answer 1

我相信在这两行：

<permission android:name="PACKAGE_NAME.permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name="PACKAGE_NAME.permission.C2D_MESSAGE" />

该PACKAGE_NAME应更改为您的实际包名，在您的示例中为com.company.mobile( 元素中的package属性）。

所以请尝试：

<permission android:name="com.company.mobile.permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name="com.company.mobile.permission.C2D_MESSAGE" />
