MainLauncher = true, ⼀一、Xamarin.Android隐藏应⽤用图标的⽅方式 1、Xamarin.Android启动Activity的 类“BoowaySurveyApp\BoowaySurveyApp.Droid\SplashActivity.cs”，指定 Name [Activity( Name = "pwkc.SplashActivity", Label = "@string/ApplicationName", Theme = "@android:style/Theme.Light.NoTitleBar", NoHistory = true, ScreenOrientation = ScreenOrientation.Portrait, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation )] 2、在AndroidManifest.xml添加以下代码，参 考http://www.mamicode.com/info-detail-2167068.html 

3、Xamarin.Android调起隐藏应⽤用的代码 Intent intent = new Intent(); ComponentName componentName = new ComponentName("com.booway.pwkc", "pwkc.SplashActivity"); intent.SetComponent(componentName); var uri = Android.Net.Uri.Parse("pwkc.SplashActivity"); intent.SetData(uri); // ⾮非隐藏应⽤用调⽤用⽅方式 //Intent intent = this.PackageManager.GetLaunchIntentForPackage("com.booway.pwkc"); //intent.AddCategory(Intent.CategoryLauncher); //intent.SetAction(Intent.ActionMain); this.StartActivity(intent); 参考资料料： 1、An Introduction to Xamarin.Forms: http://www.cnblogs.com/yuzukwok/p/3884377.html 2、Xamarin Forms: PCL vs. Shared Project http://hotkrossbits.com/2015/05/03/xamarin-forms-pcl-vs-shared-project/ ⼆二、Xamarin.Android启动第三⽅方应⽤用 // 定义通讯组件 Intent intent = currentActivity.PackageManager.GetLaunchIntentForPackage("c om.booway.map"); // 执⾏行行动作 intent.AddCategory(Intent.CategoryLauncher); intent.SetAction(Intent.ActionMain); intent.PutExtra("toolType", toolType); intent.PutExtra("userId", userId); intent.PutExtra("projectId", projectId); currentActivity.StartActivity(intent);
