Android Studio NDK編譯配置

apply plugin: 'com.android.application'android {    compileSdkVersion 25    buildToolsVersion "25.0.2"    defaultConfig {        applicationId "zhw.jpegclapp"        minSdkVersion 21        targetSdkVersion 25        versionCode 1        versionName "1.0"        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"        ndk {            moduleName "libjpegNativeLib"            ldLibs "log", "z", "m"            abiFilters  "armeabi-v7a"        }    }    buildTypes {        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }    externalNativeBuild {        ndkBuild {            path 'src/main/cpp/Android.mk'        }    }}dependencies {    compile fileTree(dir: 'libs', include: ['*.jar'])    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {        exclude group: 'com.android.support', module: 'support-annotations'    })    compile 'com.android.support:appcompat-v7:25.0.1'    testCompile 'junit:junit:4.12'}

2.ndk中要使用__android_log_print 列印： 在Android.mk中加入

LOCAL_LDLIBS+= -L$(SYSROOT)/usr/lib -llog
