Pro Android Apps Performance Optimization

Summary

Years ago, Java had a bad reputation for performance, but today this is no longer true. The Dalvik virtual machine, including its Just-In-Time compiler, improves with every new release of Android. Your code can be compiled into native code that takes advantage of the latest CPU architectures without you having to recompile anything. While implementation is important, your highest priority should be to carefully select data structures and algorithms. Good algorithms can be pretty forgiving and perform quite well even without you optimizing anything. On the other hand, a bad algorithm almost always gives poor results, no matter how hard you work on its implementation.

Finally, never sacrifice responsiveness. It may make your application ...
