Android Multithreading Masterclass from Udemy

Multithreading is an essential topic in Android development because, to write snappy and reliable Android applications, you must use more than one thread. Unfortunately, multithreading is also a very complex technique that introduces unique challenges. Incorrect multithreaded code manifests itself as unresponsive user interfaces, freezes, memory leaks, crashes and other bugs, all of which can be very challenging to find and fix.

In this course, you'll dive into the fundamentals of multithreading and learn to write correct and performant multithreaded code of any complexity in your Android applications.

Topics covered in this course:

What a thread is
Why multithreading is uniquely challenging
Keep the user interface responsive
Make your multithreaded code thread-safe (i.e. correct and reliable)
Analyze the performance of multithreaded code
Manage up to hundreds(. ) of concurrent threads
Compare several multithreading frameworks for Android, including AsyncTask, RxJava and Kotlin Coroutines
More...

You'll practice everything you'll learn here by solving a series of carefully designed, hands-on exercises. So, after completing this course, you'll have extensive hands-on experience with multithreaded code.

We'll review several popular concurrency frameworks and see how they accommodate the same complex multithreaded feature. This will allow you to grasp the full landscape of multithreading in Android ecosystem. This will allow you to choose the framework you like the best to use in your Android projects.

So, if you want to become an expert in Android multithreading, this course is perfect for you.

Reviews summary

Mastering android multithreading: concepts to coroutines

According to students, this "Android Multithreading Masterclass" is a highly recommended resource for Android developers seeking to deepen their understanding of complex concurrency. Learners praise the instructor's exceptional clarity in explaining concepts like thread safety. The course provides hands-on exercises crucial for preventing memory leaks. While some find it challenging for beginners due to assumed prior knowledge, its comprehensive coverage of RxJava and Kotlin Coroutines offers immediate applicability for real-world projects.

Provides a robust theoretical foundation for understanding concurrency principles.

"The deep dive into multithreading fundamentals, including low-level concepts, sets this course apart."

"This course really helped me understand the 'why' behind many concurrency patterns."

"Before this course, I was just using `AsyncTask` without fully understanding the underlying principles. Now I feel confident tackling complex concurrency problems."

Offers a complete overview and comparison of popular concurrency frameworks.

"I especially appreciated the sections on RxJava and Coroutines, which are directly applicable to my work."

"The focus on practical application and comparing different frameworks (AsyncTask, RxJava, Coroutines) gives a complete picture."

"This course allowed me to grasp the full landscape of multithreading in Android ecosystem."

Carefully designed exercises crucial for solidifying knowledge and practical application.

"The exercises were challenging but crucial for solidifying the knowledge."

"The hands-on exercises really made the concepts stick."

"I gained extensive hands-on experience with multithreaded code from solving the series of carefully designed exercises."

"The exercises are well-designed and really reinforce learning."

Exceptional clarity in demystifying complex multithreading concepts.

"This masterclass truly demystified Android multithreading for me. The instructor explains complex concepts like synchronization and thread safety with incredible clarity."

"The way the instructor breaks down concurrency issues and explains 'Happens-Before' was a game-changer."

"I've always struggled with thread synchronization and race conditions, but the clear explanations and practical exercises here finally made it click."

The thorough coverage of AsyncTask is historically relevant but some find it a bit outdated for current practices.

"I found the older sections on AsyncTask a bit dated, but the comparison with newer technologies like Coroutines was valuable."

"I noticed that the AsyncTask section, while historically important, occupies a significant chunk which might be better used for more advanced Coroutines topics."

"My main feedback is that some sections, particularly around AsyncTask, felt a bit drawn out, though they are foundational."

Course intensity and assumed prior knowledge may overwhelm novice developers.

"The course is quite dense. While the content is thorough, it felt overwhelming at times, especially without strong prior Java/Kotlin concurrency knowledge."

"It’s definitely for intermediate to advanced developers, not beginners."

"As a junior developer, I expected a bit more hand-holding for the initial concepts. It jumps into complex ideas quickly. Not for beginners."
