On your Android emulator question, if "Visual Studio Emulator for Android" does not appear in Add/Remove Programs, you'll need to go to Add/Remove Programs->Visual Studio 2015 CTP5, modify the installation, and add the Visual Studio Emulator for Android.
If "Visual Studio Emulator for Android" does appear in Add/Remove Programs, then the blank adb.exe window is a known issue in CTP5 that occurs sometimes when Cordova Tools and the Android Emulator are unable to communicate. To verify that this is the problem, create a new Visual C++ Android Native Activity project and attempt to run the default empty project against the emulator ("VS Emulator KitKat Phone"). If you are able to connect and run the emulator in a Visual C++ Native Activity application, then the issue is with Cordova Tools, and you can follow the steps below:
- Go to your Program Files directory and navigate to "Microsoft Visual
Studio 14.0\Common7\IDE\Extensions\"
- Search for Microsoft.VisualStudio.MultiDeviceHybridApps.dll. There will be two copies in "Microsoft Visual Studio 14.0\Common7\IDE\Extensions\"
- One will be underneath the "Microsoft\Emulator for Android" folder
- The other will be under a folder with a random hash name (always changes, but it will be something unreadable like "xf1nsyzl.5ur").
- Copy the version of Microsoft.VisualStudio.MultiDeviceHybridApps.dll from the second folder (the one with the random hash name) in to the "Microsoft\Emulator for Android" folder (replacing the old version in that location).
- Navigate to "C:\Users[your username]\AppData\Local\Microsoft\VisualStudio\14.0\Extensions" and delete the contents of this folder (it's the cache).
Restart Visual Studio and the Visual Studio Emulator for Android should work properly in Cordova projects.
