is there tips for android studio

Answer 1

www.tutorialspoint.com has some great tutorial videos on this subject, make sure you have a good PC too.

If you have low RAM, restart android studio twice every hour.

If you are offline and want to add library without gradle, download and paste library in libs folder under app folder, and add the dependency through file.

Genymotion or Bluestack insted of adv is much efficient, as they are pre configured.
