Android developer portal with tools, libraries, and apps

DebugOverlay is an Android library that allows developers to easily add custom overlay window/view for debugging purpose.

You can use it to show some performance related metrics such as cpu, memory, and fps. Or you can show logcat messages within your app for light debugging.

This library is fully customizable in terms of what you can show on the overlay. If you want to show something other than what's being provided, please go ahead and create your own overlay module!
