我正在使用 android gradle 实验插件来构建一个带有一些本机代码的应用程序模块。此本机代码使用带有预构建 .so 文件的库,我通过 android 库模块将其捆绑到 .aar 文件中。.aar 文件构建良好,但是如何将 app 模块中的本机代码模块链接到 .aar 模块中预构建的 .so 文件?gradle 实验文档没有提到这种情况。
另外,如果可能的话,我想将包含文件打包到 .aar 文件中(尽管它们不应该与最终应用程序一起打包)。
在 /prebuiltlib 中:
build.gradle
-src/
--main/
---jniLibs/
----libfoo.so
这是gradle文件:
/prebuiltlib/build.gradle
apply plugin: "com.android.model.library"
model {
android {
compileSdkVersion 25
buildToolsVersion "25.0.3"
defaultConfig {
minSdkVersion.apiLevel = 21
targetSdkVersion.apiLevel = 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles.add(file("proguard-rules.pro"))
}
}
}
}
dependencies {
compile fileTree(dir: "libs", include: ["*.jar"])
compile "com.android.support:appcompat-v7:25.3.1"
}
这里是 /app/build.gradle,注意 ??? 我不知道该放什么:
import org.apache.tools.ant.taskdefs.condition.Os
apply plugin: 'com.android.model.application'
model {
repositories {
libs(PrebuiltLibraries) {
// ??? is this right, and does this go into app/build.gradle or mylib/build.gradle?
foo {
binaries.withType(SharedLibraryBinary) {
sharedLibraryFile = file('???/libfoo.so')
}
}
}
}
android {
compileSdkVersion = 25
buildToolsVersion = '25.0.3'
defaultConfig {
applicationId = 'com.jeremy.stackoverflow.sample'
minSdkVersion.apiLevel = 21
targetSdkVersion.apiLevel = 21
versionCode = 1
versionName = '1.0'
}
ndk {
platformVersion = 21
moduleName = 'native-activity'
toolchain = 'gcc'
toolchainVersion = '4.9'
stl = 'gnustl_shared'
abiFilters.add('armeabi-v7a')
ldLibs.addAll(['log',
'android',
'EGL',
'GLESv2'
])
// ??? How do I add include paths from the .aar module?
cppFlags.add('-I' + file('???/include'))
cppFlags.addAll(['-std=c++11', '-fexceptions'])
}
sources {
main {
jni {
dependencies {
// ??? Is this right?
library 'foo' linkage 'shared'
}
}
jniLibs {
source {
// ??? Do I need one of these for the libs in the .aar?
srcDir file('???/jniLibs')
}
dependencies {
// ??? Is this right?
library 'foo'
}
}
}
}
buildTypes {
release {
minifyEnabled = false
proguardFiles.add(file('proguard-rules.pro'))
}
}
}
}
dependencies {
println rootProject.getName()
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:25.3.1'
compile project(':prebuiltlib')
}
