Understanding the structure of Java code is key to being a good Android programmer. One topic that should be understood better by most developers is concurrency. Every machine can perform more than one task at a time. For example, you are able to listen to music, browse the Internet, and have Android compiling in the background. Java, which is the main language of Android, is perfectly ready to handle more than one process at the same time.
There are two basic units of execution: processes and threads. New CPUs available both on PCs and phones have more than one thread, that’s why some new Intel chips can run up to 12 threads at the same time. The number of processes is greater, and shared among the number of currently available threads. That does not mean that a single-core processor doesn’t support concurrency. It does, but the performance will be lower than on an eight-core machine.
If you want to learn about concurrency in Java, you should check out a guide written by XDA Senior Member sak-venom1997. Sak-venom1997 put forth tremendous effort to thoroughly explain concurrency handling in Java. By following suggestions from this guide, you can get the most performance from your application and optimize it to use all threads available on your device.
The guide can be found in its original thread. If you are an app developer or you are planning to become one, don’t hesitate to go there to learn more._________
