问题描述
我有来自供应商的.so文件,只支持“arm”。 目前它对我的Android应用程序完全正常。 不知何故,我想使用Android Studio模块分离实现,因此我可以按照本教程将模块导出为Jar。
导出JAR时,构建过程会返回错误

日志说gradle试图建立针对mips但由于不兼容的库而失败,因为我只有arm库。 我的问题如何跳过针对mips的构建过程? 或者是否可以针对仅ARM架构?
的build.gradle
apply plugin: 'com.android.model.library'
model {
android {
compileSdkVersion = 23
buildToolsVersion = "22.0.1"
defaultConfig.with {
//applicationId = "com.test.remote"
minSdkVersion.apiLevel = 19
targetSdkVersion.apiLevel = 21
//versionCode = 1
//versionName = "1.0"
}
}
android.ndk {
moduleName = "remote_client"
//CFlags += "-DANDROID_NDK"
CFlags += ['-std=c99', '-fstrict-aliasing']
ldLibs += ["log", "remoted_client"]
}
android.buildTypes {
release {
minifyEnabled = false
proguardFiles += file('proguard-rules.pro')
}
}
android.sources {
main {
jni {
source {
srcDir 'src/main/jni'
}
}
jniLibs {
source {
srcDir 'src/main/jniLibs'
}
}
}
}
android.productFlavors {
create("arm") {
ndk.with {
abiFilters += "armeabi"
ldFlags += "-Lsrc/main/jniLibs/armeabi"
}
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.0.1'
}
task clearJar(type: Delete) {
delete 'mylib.jar'
}
task makeJar(type: Copy) {
from('build/intermediates/bundles/release/')
into('release/')
include('classes.jar')
rename ('classes.jar', 'mylib.jar')
}
makeJar.dependsOn(clearJar, build)
1楼
在Android SDK 26,NDK 15.2上测试
在文件app/build.gradle
:
android {
defaultConfig {
ndk {
abiFilters 'arm64-v8a'
将仅为arm64-v8a
或所有当前未弃用的ARM目标构建:
abiFilters 'arm64-v8a', 'armeabi-v7a'
ABI列表目前位于: :
在Ubuntu 17.10主机,Android Studio 3,Android SDK 26,NDK 15.2和Android 6.0.1设备上进行了测试。
示例项目。
2楼
只需将abiFilters
移动到android.ndk部分:
model {
android.ndk {
moduleName = "remote_client"
CFlags += ['-std=c99', '-fstrict-aliasing']
ldLibs += ["log", "remoted_client"]
abiFilters = ['armeabi']
}
}
3楼
最后我做到了。 这是禁用特定任务的示例。 在build.gradle上添加此行
tasks.getByPath(":app:linkMipsDebugRemoteDesktopSharedLibrary").enabled = false
