Visual Studio 2015 development Android app startup debugging always fails to complete application deployment solution

After you create an Android app project, start debugging directly and discover that visual Studio Emulator for Android has run successfully, but the app is always in build (wait longer than 1 hours) and is not deployed to the emulator as expected via ADB. Export the app directly to the APK and drag it to the simulator to deploy directly, prompting:

File transfer failed. Error:unable to install the file through ADB. Adb.exe not found. Make sure has Android SDK Tools installed.

View the list of processes found Adb.exe has been started and communicates with Visual Studio, but Xde and adb.exe do not communicate. This should be due to xde not locating the Android SDK path. So run process Monitor, try to drag the apk again, and finally find Xde find the registry key named "Hkcu\software\microsoft\visualstudioemulator\android\adbpath", Add the corresponding key-value problem resolution. Suspicion and I did not have a relationship with the Android SDK installed directly through Visual Studio, causing some settings to not take effect.
