From morning, I was learning the basics of the android studio, how to start and where to start from. I just got a knowledge how to place the buttons, text and some more attributes.
To run a apk, we need a virtual device in which we can test our apk. For that purpose, I installed a pixel 3 software in my device. Today, the main thing which I learnt was android life cycle. It shows what process will be carried out when running a application. I just tried it out and it just worked awesome.
