Did you realize that there are over 8 million mobile app developers in the world? With all of this competition, you will have to work hard to set your apps apart from the crowd.
Failing to adequately construct and test a mobile app will only lead to performance problems in the long run. The first step of the app development process is writing the code. Many developers use Java as their programming language due to how effective and easy to use it is.
Are you looking for a way to increase the performance of your Java-based mobile application? If so, consider the following tips for success.
Avoid Optimizing Before You Know it is Completely Necessary
One of the most important tips you need to remember when trying to make your Java-based app better is to avoid optimizing before you are certain it is necessary. The biggest mistake that most new developers make is replacing standard libraries with highly complex optimizations when it is not needed.
Usually, premature optimizations will take up a lot of time and will make your code extremely hard to read and maintain. In most cases, the optimizations a new developer makes will not provide any benefit to the mobile app in question.
Defining how fast your application code needs to be is the first thing you need to do. Once you know how quick response times need to be for APIs, you can determine which parts of your app are in need of improvements. Failing to have this benchmark in place will only lead to lots of busy work and not a lot of results.

Profilers Can Help You Find the Real Bottlenecks
Once you have an idea regarding which parts of your app need to be optimized, you have to consider how to handle this take. The first way to handle this problem is by looking at your code and identifying which parts look problematic.
If you want to save time, you can always use a profiler to help you find coding issues. These profiler programs will give you a detailed breakdown of your code’s behavior and performance. With this information, you should have no problem getting issues fixed in a timely manner.
Creating a Performance Test Suite for Your App
If you are looking for a way to avoid problems during the launch of your app, then developing a test suite may be a good idea. The test suite you design should be able to put the entire app through the paces. This will help you see what the app can handle and where changes need to be made.
Apps that utilize the power of databases and caches definitely need to be tested thoroughly before they are deployed. You should also use this practice if you are planning on updating an existing app. The last thing you want is for your update to make your app crash. While thoroughly testing your app may take time, it will be worth the effort you invest.

Use Primitives Whenever You Can
Improving the performance of your Java-based app is easy when using primitives whenever possible. Using wrapper classes will usually make your JVM work harder and will increase the amount of memory used. So instead of using Integer in your code, use it instead. Even changing Double to double can help to make your app run more efficiently over time.
You may also want to be wary of using programs like BigInteger or BigDecimal. While they are a bit more precise, this precision comes at a cost. These programs will use more memory and slow down code calculations dramatically. Consulting with a more experienced app developer can help you figure out whether using these programs is the right fit.
Check out the Current Log Level
Before creating a debug message, you need to check the current log level first. Neglecting to do this may lead to you creating a string in your log message that will only be ignored. During the coding process, you have to make sure all of your bases are covered in order to avoid serious mistakes.
Cache Expensive Resources
For most developers, caching is a must when trying to avoid the repeated execution of frequently used code snippets. Reusing these resources is a lot cheaper than creating new ones time and time again.
Caching database connections in a pool can help you save time. Finding little shortcuts to use during the coding process can make this job much easier and far less stressful.
The more apps you code, the more you will be able to learn. With the right tools and mindset, you can create apps that work properly.
