Official documentation for Android
The Android world is changing with each version, and more from a developer perspective. For this reason, it is common for educational material and information on the Internet to become outdated. The only way to stay updated is to communicate official documentation for Android, right from Google's hands.

Material Design
If you want the apps you make to look great without working, you have to look before or after Official Material Design documentation, related to Android, but kept separate as they are limited and not just Android.
These documents include different elements of the Performance Diagram, as well as recommendations for that what to do and what not to do and new opportunities to customize Material Theming.
Examples of code
If you are one of those who prefer not to start from a blank page, a repository with Android sample code is great, 220 sample applications With just a click, they are both Java, Kotlin or C / C ++. You can do a search, sort by themes and each instance is hosted on GitHub, so it will cost you nothing to compare it to your PC.
In addition, these sample applications are accessible directly from Android Studio, so if you want to look at how this is done, you need to import an example app from the Android Studio Welcome window, Import a sample code for Android.
Jetpack
If you are starting with the Android app right now, you can pay attention to Jetpack at first, but soon you will have to deal with this support library conversion.

Google Codes
Codelabs are something similar an exercise where you have to complete a series of steps. Some of these Codes guide you to create a simple application, while others are part of a workshop or focus on specific applications. Typically, each test takes no more than a few minutes.
