Major Android Performance Problems That App Developers Have To Face

Behind every great thing, there is a great mind. The same applies to the creative brains of those app developers who make the most and best use of their creative skills and come up with apps that have made all your daily chores simpler than before.


From games like Candy Crush Saga to e-Book reader like Wattpad, or from news apps to weather apps, almost every app you see today is the result of the highly creative brains of these app developers. However, when a developer starts working on an Android app, there are several areas that cannot be left behind without utmost care and consideration. The problem either occurs in the designing phase or in the implementation phase, but it severely affects the performance and efficiency of the app.


So, let’s talk about some vital problems that are very common in Android, and almost every app developer has to face these issues.



Many a times, it is seen that app developers don’t pay heed to the memory management or Malloc. But it is important to take note here that whatever programming language an app developer uses, the memory management is automatically done either by the garbage collector, or it is at times manually done by allocating and freeing during the process. Whether it is C/C++ or JAVA, every language has its own way to handle the memory, but the facility many times lead the app developers to neglect the memory management.


However, the garbage collector has its own severe effects on the app’s performance. It is found that prior to Android version 5.0 Lollipop, all the activities of app came at a halt when the garbage collector ran. For instance, let’s say you are writing a game, then the app needs to reduce each frame in 18ms for 64fps. If you are impudent over the memory allocation at every frame, you let GC run to either every frame or every periodic few frame and stop all other functions of the app.


RGB 565 format is also a great tool to improve the memory footprint up to 50% in your app where each pixel makes use of just 2 bytes and get encoded through RGB channels. For instance, red will be stored with 5 bits while green with 6 bits of precision. It is widely used for thumbnails.




It is a well-known fact that energy gobbled up by the smartphones work through the network I/O. When you are writing for either desktop or server, you most likely ignore the cost of I/O operation in terms of energy. It is found that almost over 60% of energy is spent in the third modules for advertisement, especially in a free app. The data not only irritates the developers, but the users, as well. The idea is to make a module that can monitor the energy spending, reduce the cost, and enhance the battery efficiency.


Memory Data Serialization


It is a new tool to save your data on the cloud or store your data as per your convenience. However, the standard mode of data serialization is not efficient enough and is not free. A binary mode of data serialization is anytime welcomed, as it is resource-friendly in terms of codes and runtime overhead. Nano Proto Buffers and Flat buffers are the exact examples of binary mode.




In the end, I would like to say that the path for an Android App developer is not smooth; however, apart from these three pitfalls along with trending, the app developers need not do much more to increase the app performance. A better understanding and use of right tools is the key behind a high perform and successful app.
