No toolchains found in the NDK toolchains folder for ABI with prefix: arm-linux-

Android Studio中遇到如下编译错误时：

No toolchains found in the NDK toolchains folder for ABI with prefix: arm-linux-

最简便解决方法： 在build.gradle中添加：

android {
    android.ndkVersion "21.4.7075529" // (or whichever NDK 22- version you have installed)
