Android Studio中的Android NDK构建过程

Question

I am trying to get the sample app of antidote running ( source code ).

I am confused as to how I need to run my app in Android Studio. I put the C-source files in the /jni folder, installed Cygwin and run the command ../android/android-ndk-r10d/ndk-build NDK_PROJECT_PATH=app/src/main/ from in the /myworkspace/myApp -folder.

I don't seem to be getting any errors, and a /libs folder has been created with in it a library, as depicted in the image below.

However, when clicking the green run-button, Android Studio still gives errors in :app:compileDebugNdk . Since the code is compiled, does the ndk still need to be run? How do I turn this off? And do I still need to somehow install the library ndk-build has made?

This is my build.gradle for the project:

sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

And this is the build.gradle for the Module:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.signove.health.service"
        minSdkVersion 15
        targetSdkVersion 21
    }

    sourceSets.main{
        jni.srcDirs = []
        jniLibs.srcDir 'src/main/libs'
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

You're disabling automatic ndk-build calls from sourceSets.main{ jni.srcDirs = [ ] } Then you may want to make Gradle plugin call it adding the ndkBuild task .

Check this answer out: execution failed for task ':app:compileDebugNdk' failed to run this command ndk-build.cmd
