Advanced Android Development: Performance Optimization & Debugging Training Course

Rating

9/10

Duration

4 Days

Course Overview

This course focuses on performance optimization and debugging techniques in Android development. Participants will learn how to profile Android applications, optimize memory usage and CPU performance, and reduce app crashes and ANRs (Application Not Responding). The course covers best practices for debugging using Android Studio tools, memory leak detection, and efficient exception handling. By the end of this training, participants will be equipped with advanced techniques to develop smooth, efficient, and crash-free Android applications.

Format of Training

  • Instructor-led sessions
  • Hands-on lab exercises
  • Interactive discussions
  • Practical coding demonstrations
