首先，將so文件拷貝至libs目錄下
然後就是編寫我們的build.gradle文件。
關於so文件引入的配置很簡單，代碼配置如下：
task nativeLibsToJar(type: Zip, description: "create a jar archive of the native libs") { destinationDir file("$projectDir/libs") baseName "Native_Libs2" extension "jar" from fileTree(dir: "libs", include: "**/*.so") into "lib" } tasks.withType(JavaCompile) { compileTask -> compileTask.dependsOn(nativeLibsToJar) }
自定義一個任務，在其中指定項目所依賴的so文件的目錄，這裏用了**/*.so來寫，爲了省事，指定需要拷入的目錄 into "lib"，那麼動態運行庫就被拷入到lib目錄中。
完整的build.gradle文件如下：
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "包名"
minSdkVersion 15
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
task nativeLibsToJar(type: Zip, description: "create a jar archive of the native libs") {
destinationDir file("$projectDir/libs")
baseName "Native_Libs2"
extension "jar"
from fileTree(dir: "libs", include: "**/*.so")
into "lib"
}
tasks.withType(JavaCompile) {
compileTask -> compileTask.dependsOn(nativeLibsToJar)
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.1.0'
testCompile 'junit:junit:4.12'
compile files('libs/classes.jar')
