Reasons Why You May Need Linux Knowledge in App Coding
The world has gone mobile and much of this recent technological shift to the mobile world can be attributed to the need for mobile apps which have successfully enabled the users to automate many of the tasks that they need to get involved in. Today, there are many apps, both for android and iOS platforms which make it easier for users to interact with various online platforms without many problems.
I’m an app developer for android. For several years I’ve been using my programming skills in Java to make my ends meet. Most of the gigs that I ever landed on were quiet paying and enabled me to cater for my daily expenses and became a source of livelihood.
However, about two years back I realized that most of the app developing gigs that I applied for required the use of Linux as part of the job experience. I had none. This meant me to inquire the necessary Linux experience that was needed for an android app coder. Below I want to detail the uses of Linux for app developers and why it is vital for you to have knowledge of it.
Linux is Critical in the Development Environment of Android Apps
The best thing about Linux is the fact that it is open source meaning that developers have a right to modify the Linux kernel (a core part of the OS) to ensure that the modifications fit their needs.
Basically, what I’m trying to say is that Linux already presents developers with an already pre-built operating system kernel which can later be manipulated to functions as one wish. Note, you don’t have to start from scratch because the kernel is already re-built and also maintained. You are just tasked with modifying the kernel to fits your needs.
The fact that the OS is open source also gives one the ability to do the modifications as suited without infringing the rights of the OS developers. But, it should be noted that there is a limit on the modification that one can make according to the license agreement of the open source. This, however, isn’t a barrier since the licensing allows almost all modification that you can think about.
Use of Native Development Kit to Interact with Linux Core OS
In my earlier case of android development I normally used my java skills and the Android Software Development Kit (SDK) for the apps that I coded. However, there arises situations whereby there may be no immediate update of the compilers hence the app becomes slow. In this instance, you may be forces to program your app using Android Native Development Kit (NDK).
Basically you are programming the app using C and C++ by calling C within your java environment. This lets you compile and build files needed to have an updated version of the app through the use of Linux as you can now embed new files on the application packages files (apks) for use on android devices.
This can be vital especially if you want to have files that will be supported in future versions of android as well as enable you to embed tutorials and documentation about the app thus showing your app authenticity to the users and providing them with a more user-friendly interface through samples.
Other instance whereby you might be mandated to have extensive Linux knowledge in app development include cases in which Linux is the core OS of the remote server of the app and thus there is need to have a clear line of communicating between the app and the host with minimal problems.
