Libc is available as both a static and shared library. Information about these libraries, the tradeoffs involved, and how to use them. Restart Android Studio to apply the changes.The NDK supports multiple C runtime libraries. For example, if you installed the NDK at "C:\android-ndk-r21", then the value would be "C:\android-ndk-r21". Under "System Variables", click on "New" to add a new variable.Įnter "ANDROID_NDK_HOME" as the variable name.Įnter the path to your NDK installation directory as the variable value. You can do this by right-clicking on the "This PC" icon on your desktop or in File Explorer, selecting "Properties", and then clicking on "Advanced system settings" on the left-hand side.Ĭlick on the "Environment Variables" button at the bottom of the window. Open the Environment Variables settings in Windows. To set ANDROID_NDK_HOME so that Android Studio does not ask for ndk location in Windows, you can follow these steps: Below are a few methods for setting this variable on different operating systems: Method 1: Windows To avoid this issue, it is possible to set the ANDROID_NDK_HOME environment variable to the location of the NDK installation, so that Android Studio can automatically locate it without prompting the user. This can be a repetitive and time-consuming task, especially when working on multiple projects. However, when setting up a new project in Android Studio, the IDE may prompt the user to specify the location of the NDK installation. When developing Android applications, the Android Native Development Kit (NDK) is often used to include C/C code in the app. ![]()
