Thank you. In this articleThis topic contains information to help you resolve issues that you may experience when you're using the Visual Studio Emulator for Android. Warning When the emulator is installed, the setup program checks the prerequisites for running the software. It displays warnings if the prerequisites are not present, but it does not require them for installation. This topic contains the following sections.
Before you startBefore you begin troubleshooting, it may be useful to review the following topics:
Emulator fails to installIf you don't have Hyper-V installed, you will see the following message when you try to install the emulator. You must have a machine that supports HyperV and it must be enabled. Note This message applies both to the Visual Studio Emulator for Android and the Windows Phone Emulator. Windows 8.1 and Windows 10 support the emulator. If you see this message, check the System requirements for the Visual Studio Emulator for Android to see whether you can run the emulator. Cannot connect to network destinations on a domain or corporate networkThe Visual Studio Emulator for Android appears on the network as a separate device with its own IP address. It is not joined to a Windows domain and it does not share domain or workgroup credentials with the host computer. If your network requires domain or workgroup authorization for basic network and Internet connectivity, contact your IT administrator for an exception. This exception allows your development computer to serve as a boundary machine and to accept connections from non-domain-joined network devices like the emulator. The Visual Studio Emulator for Android also uses its own set of MAC addresses. If you can't access network or Internet resources from the emulator, check with your IT administrator to make sure that the emulator's MAC addresses have been authorized on your network. To view the emulator's MAC addresses
Cannot connect to network destinations when network settings require manual configurationTo connect to network destinations from the emulator, your network must meet the following requirements:
Emulator starts slowly, fails to start due to a timeout, or app deployment failsUnder certain conditions, the emulator takes several minutes to start or fails to start due to a timeout. When the emulator fails to start, you see the following message: App deployment failed. Please try again. The following conditions can result in this error.
Emulator fails to startIf the emulator was working previously, but does not work now, go through the following tasks. If you are using the emulator for the first time, see Emulator fails to start (first use) before you try these steps.
Emulator fails to start (first use)If the emulator does not start, go through the following tasks to identify and fix the issue.
Computer fails to boot after installing the EmulatorThis problem can occur when the following conditions are true:
Visual Studio gets stuck trying to deploy the app to the emulator or the emulator does not appear as a debug target in other IDEsIf the emulator is running, but it does not appear to be connected to ADB (Android Debug Bridge) or it does not appear in Android tools that make use of ADB (for example, Android Studio or Eclipse), you may need to adjust where the emulator looks for ADB. The emulator uses a registry key to identify the base location of your Android SDK, and looks for the \platform-tools\adb.exe file under that directory. To modify the Android SDK path used by the emulator:
Emulator stops responding because it couldn't set up the UDP portYou may experience this issue due to incompatibility with Xamarin Player. If the emulator appears to stop responding or if you see this error message, "The emulator is unable to connect to the device operating system: Couldn't set up the UDP port. Some functionality might be disabled", you may be experiencing this issue. Take the following steps.
Cannot attach debugger to a Xamarin projectIf you are running Windows 10 with Intel Skylake processors, Xamarin apps might fail to run in the emulator or the Visual Studio debugger might not attach to them. This is due to an issue with Hyper-V and Skylake processors. Take the following steps as a workaround.
Emulator fails to run app that uses Google Play ServicesThe emulator does not ship with the libraries for Google Play Services. However, the emulator does support drag-and-drop installation of flashable zip files. Drag and Drop of a file, APK, or flashable zip file does not workThe emulator uses ADB.exe to facilitate file transfer when you drag and drop a file onto the screen. If you encounter an error when you try to drag and drop a file, this probably indicates that the emulator is not connected to ADB.exe. To resolve, follow steps in Visual Studio gets stuck trying to deploy the app to the emulator or the emulator does not appear as a debug target in other IDEs. Resolution of screenshot is incorrectIf you take a screenshot using the Screenshot tab in the Additional Tools window and the resulting image is of an unexpected size, you may need to adjust the zoom level of the screen before choosing Capture. The emulator takes screenshots at the resolution of the screen on your host PC monitor. Emulator fails to render OpenGL contentThe emulator renders OpenGL content using your host machine's GPU and uses the ANGLE project to convert these calls to and from DirectX. If your application renders correctly on a device but incorrectly on the emulator, it is likely that the device is mitigating an incorrect OpenGL call (for example, using shader variables that do not match). Emulator does not respond to multi-touch gesturesIn some cases, the emulator will start and not respond to multi-touch either through direct interaction from your touch-enabled display or using the Multi-Touch Tool on the emulator toolbar. If this is the case, choose the Rotate button on the emulator toolbar and attempt to use multi-touch again. If the issue persists, read the Emulator fails to render OpenGL content issue.
