Multithreading
Multi-threading allows a process to make more efficient use of modern hardware by allowing code to execute asynchronously. It can drastically improve the performance of any app; however, it can be tricky to get right, making this an important topic for any programmer.
Event handling
Event-based design patterns are very common in modern applications, especially in the development of user interfaces.
Configuration
Configuration is a crucial component of most systems and frameworks. It allows a developer to tune performance and control access to features.
Fragments
A fragment represents a behavior or a portion of the user interface in an activity, which has its own lifecycle, receives its own input events, and which can be added or removed while the activity is running.
UI
An understanding of user interface design is important for any good front-end developer.
Linear Layout
LinearLayout is a view group that aligns all children in a single direction, vertically or horizontally. It is one of the most used layouts which should be well known to any Android developer.
List View
ListView is a view which groups several items and displays them in vertical scrollable list. Android developers should know this essential view to make a good UI/UX experience.
Relative Layout
RelativeLayout is a view group that displays child views in relative positions to either sibling elements or the parent RelativeLayout area. Android developers should know this essential view to make a good UI/UX experience.
Responsiveness
Android devices come in all shapes and sizes so making views that look good on all of them is an essential task for an Android developer.
Battery Life Optimization
Battery life is the run time on a full battery charge. Optimizing applications to maximize battery life is one of the most important aspects of the user experience.
Asynchronous programming
Asynchronous programming is a programming method used to to run tasks asynchronously. Running tasks asynchronously can improve performance and allow applications to feel more responsive. As such, it's important for all programmers who need to write performant or responsive applications.
