This particular blog is devoted to the Android Log Viewer. It is a very useful tool when you are working with Cordova/Phonegap via command-line interface (CLI).
When a developers like you are working on CLI which is recommended by even Cordova team then the most important thing that you are going to face is that how to debug an application. Now you have an option to use eclipse, but then question arise that why the hell you are using CLI.
So the easiest choice would be to use a separate log viewer like this. Of course, the CLI would be very light weight and could work on less powerful machine as well. If you have bought a machine few years back then it might not handle currently available processing intensive applications very well. Thus the only choice left was to use CLI. But you will feel the power and beauty of this once you'll get used to it.
