While Java is the default programming language for Android, it isn’t. Here is our guide to getting started with the Android NDK. The problem with approach is that anyone can get the API key by reverse engineering.Īnother approach that was used is the gradle file approach. The Android NDK allows you to use C/C++ code in your Android apps.

Following is an example of storing an API key in strings.xml file: The Native Development Kit (NDK) is a set of tools that allows you to use C and C++ code with Android, and provides platform libraries you can use to manage native activities and access physical device components, such as sensors and touch input. However, the information are distributed.

During the starting days to Android development, we put our API keys either in strings.xml file or in gradle file. There are also many online tutorials and articles showing the basics of NDK and the usage of NDK building tools. Some of these libraries are paid and if somehow, someone gets your API key then you might land to high payment bills and many other problems. But to call these functions, we need API keys that are different for different users. In these libraries, we just call some functions according to our need and we don’t know the code of these functions and we don’t care about that.

If you reveal your secrets to the wind, you should not blame the wind for revealing them to the trees. Part 1/10While most Android apps are written in pure Java, Android's Native Development Kit (NDK) enables us to access code written in C/C++ via Java Native. Some of you might have used the XML or gradle approach to secure the API keys but these can be easily exposed by reverse engineering. Most of these services are paid and it becomes an important task to secure the API keys of these libraries in our application’s code. May be you have to use Google maps service or any Google play services. You can use NDK by manually downloading NDK and build it.

Use ' ndk-build V1 ' to display the build messages. NOTE: This setup guide was written for the Windows 10 64-bit platform. Use ' ndk-build -help ' to display the command-line options.

Start a CMD shell, change directory to the project's root directory, and run ' ndk-build ' script provided by Android NDK (the Android NDK installed directory shall be in the PATH). If you are reading this blog then you must be an awesome Android developer or you are going to be one in the future.
