Hello, Kartik here… (This is my second account) I have completed my App, and it works fast and nice with live testing… When I uploaded to play store, and got the apk, the app is hanging a lot and got very much slow. What could be the problem? I have 20 screens, and 25 images in app. Could this be the problem? Thanks 😉 ---
