Answer 1

try this

commandLine'E:\\Android\\ndk\\ndkbuild.cmd','-C',file('src/main/jni').absolutePath

replace (E:\\Android\\ndk\\) with your ndk path.

Answer 2

I met this kind of problem. First of all You have to give your NDK path in local.properties of your app.

e.g. ndk.dir=/home/user/bin/android_ndk/android-ndk-r10e

Then in my build.gradle file I had something like this for calling ndk build command.

commandLine 'ndk-build', '-C', file('src/main/jni').absolutePath

I'v change it to

commandLine '/home/user/bin/android_ndk/android-ndk-r10e/ndk-build', '-C', file('src/main/jni').absolutePath

I gave full path of NDK build. Hope it'll help you.

Answer 3

Have a look in these link below.

You must know the path where the NDK is usually at

Library/Android/sdk/ndk/<version_number>

https://developer.android.com/studio/releases?utm_source=android-studio#4-0-0-ndk-dir

and

https://developer.android.com/studio/projects/install-ndk

Answer 4

its easy for android studio 2.3.3. just follow File->Project Structure -> android NDK Location-> Click download button. after install ndk solve my problem.

Answer 5

The accepted answer is OK, but it doesn't work since android tools gradle plugin 2.3: No sdkHandler field in LibraryPlugin after updating to build tools 2.3.0, so you need to use project.android.ndkDirectory.absolutePath variable then, ie:

task ndkBuild(type: Exec) {
    commandLine project.android.ndkDirectory.absolutePath + '/ndk-build', '-C', file('src/main/jni/').absolutePath
}

Alternatively you can read ndk.dir directly from local.properties: https://stackoverflow.com/a/32649204/1028256

Answer 6

1. First of all you have to check local.properties file in your project. In local.properties check ndk path. It looks like this ndk.dir=D:\\sdk\\ndk-bundle.

2. Now go to the build.gradle(Module library) and find getNdkPath(). It will return ndk path location which concatnate the ndk-build

3. Change ndk-build --> ndk-build.cmd. It looks like this:
