Three useful android libraries
The most useful libraries for me lately is:
- Picasso – A powerful image downloading and caching library for Android.
- Butterknife – Field and method binding for Android views.
- EventBus – Simplifies the communication between components and makes your code simple.

Useful and forgettable Fragment methods
- getContext() – Return the Context this fragment is currently associated with.
- getView() – Get the root view for the fragment’s layout (the one returned by onCreateView(LayoutInflater, ViewGroup, Bundle)), if provided.
- isAdded() – Return true if the fragment is currently added to its activity.
- isHidden() – Return true if the fragment has been hidden.
- isVisible() – Return true if the fragment is currently visible to the user.
