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.
If you want you can to add the Go path into windows environment.
You will have this path in this case: C:\Users\your_account\go\.
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.

Linux – netstat command .

This tutorial come to show you how to use the netstat command with linux operating system.
To list out all the connections tcp, udp & unix on a system, we can use ‘a’ option with netstat command:

To list only the tcp connections our system, use ‘t’ options with netstat:

To list out only the udp connections on our system, we can use ‘u’ option with netstat:

To only list out Unix socket connections, we can use ‘x’ options:

To get list of all connections along with PID or process name, we can use ‘p’ option & it can be used in combination with any other netstat option:

To speed up our output, we can use ‘n’ option as it will perform any reverse lookup & produce output with only numbers (since no lookup is performed, our output will much faster):

To print only the listening ports , we will use ‘l’ option with netstat (it will not be used with ‘a’ as it prints all ports):

To print network statistics of each protocol like packet received or transmitted, we can use ‘s’ options with netstat:

To display only the statistics on network interfaces, use ‘i’ option:

To display multicast group information, we can use option ‘g’ ( that print the multicast group information for IPV4 & IPV6):

To print the network routing information, use ‘r’ option:

To get continuous output of netstat, use ‘c’ option:

To filter a single port connections, we can combine ‘grep’ command with netstat:

To use multiple commands with netstat.
Example: count the number of connections with CONNECTED value, we can further add ‘wc’ command with netstat and grep command:
