In such cases, we are using C or C++ codes along with the default standard Java codes, hence the term “multiplatform code”. But almost all of the controller code could be ported using C or C++ because, again, almost all the mobile platforms support both languages so if we can write the logic to some C-C++ code libraries and then reuse it in several target platforms that enables us to run the application without losing out on a lot of performance. When we aim to create a to program with many platform targets, we might have to rewrite most of the controller and view the code for each platform, which is really not a very smart way. Moreover, the whole platform independence-bytecode-JVM setup draws out a lot of the hardware’s performance.Īnother important factor to consider is the multi-platform code. But programming in Java can also be a bit difficult because the code becomes a more and more complex to use and comprehend. In the case of app development on Android, the above factor is seen to be a minor disadvantage. Ultimately, the whole app runs inside a JVM on the Android device. It is the bytecode that runs later with alterations depending on the platform in which the particular JVM is running. The Java source code, as mentioned above, first gets compiled into bytecode. However, in terms of Android - since we are mostly dealing with smartphones and at the most tablets factors like effecting maximum performance out of the hardware and so on - become major factors. Also, the JVM (Java Virtual Machine) that is responsible for JIT compiling and running Java bytecode is platform independent in the sense that it is available for operation on many platforms, everything from mainframes to mobile phones. Applications or algorithms written in Java compiles to its own bytecode which runs similarly across all platforms. We are all aware of how application development in Android goes hand-in-hand with the Java programming language, and how it makes matters a lot easy for app developers - owing to Java’s elegant object-oriented programming design. The NDK is hence basically a tool that helps programmers design their apps in native programming languages for a variety of reasons ranging from generating optimum performances to simplification of the code used. Many apps available in the market use a host of different programming languages apart from Java to achieve the best results. Android NDK (Native Development Kit) is a very popular tool used in application development for mobile devices.
