Android Studio 1.5.1上面对于NDK的编译进一步简化，只需要在工程的defaultConfig设置中增加如下配置就可以了：
ndk {
moduleName "jni_module"
ldLibs "log"
abiFilters "armeabi"
}
新建的工程中的app目录下的build.gradle中的内容如下：
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.my.myapplication"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
}
修改后的配置文件如下：
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.my.myapplication"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
ndk {
moduleName "jni_module"
ldLibs "log"
abiFilters "armeabi"
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
}
然后在app->src->main目录下创建jni目录就可以了。
如果此时提示：
Error: NDK integration is deprecated in the current plugin. Consider trying the new experimental plugin. For details, see http://tools.android.com/tech-docs/new-build-system/gradle-experimental. Set "android.useDeprecatedNdk=true" in gradle.properties to continue using the current NDK integration.
则在修改工程目录下的gradle.properties,在文件中新建一行，添加如下：
android.useDeprecatedNdk=true
注意，还需要在local.properties设置NDK的路径
ndk.dir=D\:\\Android\\android-ndk-r10e
默认情况下，build.gradle中的代码是不能进行调试的，需要增加两个配置项：
jniDebuggable true debuggable true
修改后的配置文件如下：
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.my.myapplication"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
ndk {
moduleName "jni_module"
ldLibs "log"
abiFilters "armeabi"
}
}
buildTypes {
debug{
jniDebuggable true
debuggable true
}
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
}
一般在debug项中增加提示即可，如果想在release中也支持Debug的话，上面两句话在release中增加即可。修改后的结果如下：
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.my.myapplication"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
ndk {
moduleName "jni_module"
ldLibs "log"
abiFilters "armeabi"
}
}
buildTypes {
debug{
jniDebuggable true
debuggable true
}
release {
jniDebuggable true
debuggable true
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
}
