In the dynamic field of Android development, mastering the foundational theories is crucial for creating robust and efficient applications. Whether you're just starting or looking to deepen your understanding, these core concepts will provide clarity and enhance your expertise. Our expert has curated four master-level theory questions along with detailed solutions to help you grasp these essential principles.

1. Activity Lifecycle
