The Android Native Development Kit (NDK) is a toolset that developers can utilize to reuse code in the C/C++ programming language and integrate it into their applications using the Java Native Interface (JNI). What is the difference between Android NDK and SDK? However, the NDK can offer an excellent way to reuse large amounts of existing C/C++ code. When considering whether you want to develop native code, consider your needs and see if the Android Framework API offers the needed functionality. Merely recording a method to run in C usually does not lead to a significant increase in performance.

Usually, candidates for NDK are standalone CPU-intensive operations that do not allocate a large amount of memory, for example, Signal processing, physical simulation, etc.

Generally, you should use native code only when your application absolutely needs it, not just because you prefer the C/C++ language. As a developer, you need to weigh the pros and cons in particular, using native code does not automatically improve performance however, it always increases the complexity of the application.

Most applications will not be able to use NDK.

JavaNative C exchanges have some additional overhead, so it's only worth it if you have a lot of processing work.

Don't think that the performance of your application can be improved by using only native code.

This is especially true for OpenGL ES apps written for other platforms. If your existing app has enough C code, the NDK can increase the development of your projects and help you keep changes in sync between Android and non-Android projects.

Another reason to use the NDK is that it is easy to transport.

Also, keep in mind that the JIT compiler in Android 2.2 also improves the performance of this code.

This means that your algorithm uses the full DalvikVM processor and can take advantage of its native execution.

In general, you should only use the NDK if your application is really processor-related.

NDK: Native Development Kit (NDK) is used for C and C ++ programming, i.e., the native Android language.ĬMake: It is an open-source system that can manage the compilation process independently of the compiler in the operating system.

LLDB: Android Studio is used for debugging the native code existing in the project.

Some basic Prerequisitesīefore using the Android NDK support in your app, you are required to download the following tools: Ideal for intensive computer operations such as mobile video games, signal processing, or physical simulation. Codes are written while learning C or C++, or other developers' code, can be reused in your Android applications. Therefore, you do not have to perform the intermediate steps needed by Java/Kotlin.Ĭode reuse: You have the option of reusing code written in C or C++ in Android applications for different platforms. On the other hand, NDK compiles the native code, i.e., Convert C or C ++ code directly into machine language through. The same goes for Kotlin, as Kotlin also runs Java behind the scenes. Why use NDKįaster performance: Generally, to convert Java code to machine-level code, we must first head to JVM, then go to JNI to run the operation. If you absolutely need to use something, you can also use third-party libraries or your own libraries. Since the source code is directly compiled into machine code on the CPU and not a language like Java, developers can get the best performance.

If there is no special requirement, you can download the latest version directly.The Android NDK (Native Development Kit) helps developers maximize the performance of their devices, which is very useful for game engines such as Unity or Unreal Engine. If you want to get better backward compatibility, you can choose the r16 version, because this is the last version that supports armeabi. If you haven’t, you can download and decompress it from the official websit: Android NDK

This article mainly explains in detail how to compile libraries and executable programs that can run under android through xmake.įirst of all, we need to prepare the ndk toolchain necessary for compiling the android native library. It’s main features are: easy to use syntax, easy to use project maintenance,Īnd a consistent build experience across platforms. Xmake is a lightweight and modern c/c++ project building tool based on Lua.
