An Android library is structurally the same as an Android app module. It can include everything needed to build an app, including source code, resource files, and an Android manifest. However, instead of compiling into an APK that runs on a device, an Android library compiles into an Android Archive (AAR) file that you can use as a dependency for an Android app module. Thus, these AAR files not only save our time but also reduce the LOC. Hence, Today I am going to share some of cool android libraries that you may heard and will definitely help you.
1. Long Shadows
Long Shadows can be used to give any view a cool looking shadow very easily. It also provides the shadow animations.
Features
Long-Shadows can render shadow for any type of view, even custom views.
It shifts the load of heavy calculations to native, to reduce overhead in Java. Thus the rendering is very fast and efficient.
The library supports fine control over shadows of a view, so two views in same ViewGroup can have different shadow parameters.
The library also support rendering multiple long shadows for a single view, simulating multiple light sources.
It allows the operations to be asynchronous to avoid blocking the UI thread for long calculations.
It supports fade out animation while rendering the shadow.
