I have installed the Android x-86 version 5.1 on VM-ware and my android can reach to the internet connection. Here, I cannot use play store, so that I use the APK mirror to download the android applications using web browser Chrome, e.g. Line, Zalo, Viber and etc.
After I have downloaded the android application, I cannot install it, when I open the file at Folder Download, it cannot be opened.
How do I install the android application on Android x-86 version 5.1?
