Using Android-NDK in Android Studio Build command fail

Issue

I am trying to add this project as Android-NDK to Android studio but I keep getting errors : https://github.com/timsu/android-aac-enc

I followed this guide to install NDK and everything related. Then I added the jni folder to the app\src\main\jni and added this line to build.gradle.

android {  
    externalNativeBuild {
        ndkBuild {
            path "src/main/jni/Android.mk"
        }
}

When I try to sync the project I get the following error :

Build command failed.

Error while executing process C:\Users\ThermalTake i7\AppData\Local\Android\Sdk\ndk-bundle\ndk-build.cmd with arguments {NDK_PROJECT_PATH=null APP_BUILD_SCRIPT=C:\Users\ThermalTake i7\Desktop\StarMe Git\starme_android-code\app\src\main\jni\Android.mk APP_ABI=armeabi-v7a NDK_ALL_ABIS=armeabi-v7a NDK_DEBUG=1 APP_PLATFORM=android-19 NDK_OUT=C:/Users/ThermalTake i7/Desktop/StarMe Git/starme_android-code/app/build/intermediates/ndkBuild/debug/obj NDK_LIBS_OUT=C:\Users\ThermalTake i7\Desktop\StarMe Git\starme_android-code\app\build\intermediates\ndkBuild\debug\lib APP_SHORT_COMMANDS=false LOCAL_SHORT_COMMANDS=false -B -n}
'C:\Users\ThermalTake' is not recognized as an internal or external command,
operable program or batch file.

After searching for some answers I tried adding this line to the build.gradle:

android {
    defaultConfig
            {
                ndk {
                    abiFilters 'x86', 'x86_64', 'armeabi-v7a','arm64-v8a'
                }
            }

And still got the same error, what am I missing?
Is adding the jni folder all that I have to do?

Also this is the Android.mk file, maybe the error is there.

Could it be because I have not included NDK_MODULE_PATH?

Solution

NDK cannot be installed in a path that has spaces. Same for projects that use NDK.

In your case, the best fix would be to move all Android SDK to a directory C:\AndroidSdk.
