Mr.Smile filled pit production so remember --ndk library, ndk-build is not an internal or external command. . . mistake

This thought probably require the following steps:

1. Download ndk

2. Configure ndk environment variables

3. add some ndk configuration in android studio

4. Write c file

The library so generated

6. Call the library so

The main purpose of this article is to record what I encountered the pit!

Let me talk about after the pit face, and that is in accordance with the two articles mentioned above, do all the work, run ndk-build, has not given an internal or external command.

1. Add the module at the defaultConfig gradle

ndk{
        moduleName "testNDK"			//名字自己取
        abiFilters "armeabi", "armeabi-v7a"	//这里是你想生成什么类型的就自己添加
    }

2. Add in the gradle module

externalNativeBuild {
        ndkBuild {
            path 'jni/Android.mk'	//这个是Android.mk文件的路径
        }
    }

After completion you can run ndk-build, generate a .so

The first writing, just for the record pit their own problems, if able to help, all the better
