1. Download both files from here.
2. Unzip both of the files on the folder
3. Open the folder wconnect, then install IpOverUsbInstaller.msi and vcredist_x86.exe
4. Go to your Windows 10 Mobile’s Settings page, then head over to Update & Security > For Developers and enable Developers Mode, as well as Device Discovery
5. Now go to the extracted wconnect folder, then open an elevated command prompt (Shift+right click > Open command window here)
6. After that, you’ll need to connect to the phone — and there’s two way of doing that (USB method is recommended): ◦If you want to connect using USB, type "wconnect.exe usb" and hit enter
6.1 And if you want to connect over Wi-Fi, type wconnect.exe 192.168.xxx.xxx (replace the xxx with your network’s IP). Find Installation of Android Apps on Windows Phone instructions here.
7. Then it’ll ask for the pairing code, just type the pairing code and hit enter
8. After that, navigate to the extracted adb folder and open an elevated command prompt
9. To make sure that your device is connected, type adb devices and hit enter to show the list of devices that are connected
10. Lastly, place the APK file that you want to install on the same directory (adb folder) and type in adb install APKNAME.apk (replace APKNAME with the APK file’s name)
11. Just wait for it to do its thing and you should be able to install the Android app on your Windows 10 device.
If you get "Status 9 - connection problem", then if this happens, unregister you device using "Windows Phone Developper Registration 8.1", tool provided alongside Windows Phone 8.1 SDK, or download the lite version from here.Afterwards you will be able to access Developer settings again. Or Hard reset, your choice.
