Understanding the Android Activity Lifecycle is crucial for managing the state of an application throughout its various stages.
Sample Answer:
The Android Activity Lifecycle consists of several states such as onCreate(), onStart(), onResume(), onPause(), onStop(), and onDestroy(). It's important because it allows developers to manage application state transitions effectively, ensuring a seamless user experience.
Serializable and Parcelable are mechanisms in Android for passing data between components.
Sample Answer:
Serializable is a default Java interface that uses reflection and is easier to implement but slower compared to Parcelable, which is an Android-specific interface. Parcelable requires a bit more effort to implement but offers better performance, making it more suitable for passing large data sets between Android components like activities and fragments.
Understanding intent types is fundamental for inter-component communication in Android.
Sample Answer:
Explicit intents are used to start a specific component within your application, while implicit intents are used to activate components from other applications in the system based on an action type or data type.
The AndroidManifest.xml file holds essential information about an Android application.
Sample Answer:
The AndroidManifest.xml file is crucial as it contains metadata about the application, such as package name, permissions required, activities, services, broadcast receivers, content providers, and more. It serves as a blueprint for the Android system to understand the structure and requirements of the application.
Memory management is critical in Android development to prevent memory leaks and ensure optimal performance.
Sample Answer:
To handle memory leaks, developers can use tools like the Android Profiler to detect memory issues, employ efficient coding practices such as avoiding static references to contexts, using weak references, releasing resources appropriately, and implementing lifecycle-aware components.
