At the beginning of my android development journey, I have built my first app.I thought it was ready to publish it in the play store. But when I tested it in another device, It didn’t behave the same,the view was bigger or not visible at all.

Android devices comes in all different shape/sizes yo your layout,views needs to be flexiable. Yes, you’ll not face this problem if you use only match_parent etc attributes but if you wanna used fixed value it’s going to occur.

There’s plenty way to solve that issue but if you’re beginner it might be too complex…
