Android developer portal with tools, libraries, and apps

A small and simple, yet fully fledged and customizable navigation library for Jetpack Compose:

• Full type-safety
• Built-in state restoration
• Nested navigation with independent backstacks
• Own Lifecycle, ViewModelStore and SavedStateRegistry for every backstack entry
• Animated transitions
• Dialog and bottom sheet navigation
• Scopes for easier ViewModel sharing
• No builders, no obligatory superclasses for your composables

A flexible view for providing a limited rect window into a large data set, just like a two-dimensional RecyclerView. It different from RecyclerView is that it's two-dimensional (just like a Panel) and it pin the itemView of first row and first column in their original location.

This is an experimental project about Android NFC functionality.

The whole idea is based on using android device as a Host Card Emulation, however we cannot simply send a byte array by realising communication enter iOS and Android because of iOS can only accept NDEF Message. So I'm enlightened by reading NFCForum-TS-Type-4-Tag which simulate the whole process command talking cross devices.
