Go – Testing Golang with android application – part 001 .

This is my first tutorial in a long series about Go and Android programming. In the limit of my free time I will try to show you how to do simple applications with the Go programming language (or known as Golang).
You need to install the Go programming language using MSI installer from here.
I set the folder with this path – C:\Go\ but my windows also put some go files under Users folder.

The next step is to install the Android NDK from here.
I install the Windows 64-bit into Users folder. You need to install at: C:\Users\your_account\go\.

Let’s see the commands to install and used it:

About the gomobile command then the help tell us:

If you have the adb command installed on your machine, you can use gomobile command with the argument install to push the APK to your mobile device.
I used Bluestacks emulator for android and the basic example working well.
