1 Minute cheatsheet to begin ANDROID development for iOS developers

This table is geared towards iOS developers who want to start working on android. You can refer this table whenever you are confused about what component to use in android, and also what tool to accomplish a task. I have tried to make it 1:1. So its easy to google the information needed.

Quicktime	Vysor
AutoLayout	ConstraintLayout
ViewDidAppear	OnResume
ViewDidLoad	OnCreate
dealloc	Destroy
ViewWillDisappear	OnPause
ViewControllers	Activity
Push/Present View Controllers	Intent intent = new Intent(this, SignInActivity.class); startActivity(intent);
PNG	WebP images (https://developer.android.com/studio/write/convert-webp)

ChildViewControllers	Fragment

onResume should be onStart and onPause should be onStop.

Because between start/stop, the views are visible. Resume/pause is more like gained/lost focus. And that’s exactly what they mean when you have multiple apps opened at once, for example on ChromeOS.
