摇篮的Andr​​oid版本为不同的处理器架构

问题描述

我要建立的4种不同的Andr​​oid CPU处理器架构采用摇篮4个单独的APK（armeabi armeabi-V7A 86 MIPS）。

I want to build 4 separate apks for 4 different Android CPU processor architectures (armeabi armeabi-v7a x86 mips) using Gradle.

我已经原生的OpenCV库建为4个CPU架构在库的文件夹。

I have native OpenCV libraries built for 4 CPU architectures in the libs folder.

libs
    -armeabi
    -armeabi-v7a
    -x86
    -mips

欲每个的apk只包含相应于正确的CPU架构OpenCV库。

I want to each apk only contains the OpenCV library corresponding to the correct CPU architecture.

目前构建脚本如下：

apply plugin: 'android'

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile project(':workspace:OpenCV4Android:sdk:java')
}

android {
    compileSdkVersion 11
    buildToolsVersion "18.1.0"

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')

        flavorGroups "abi", "version"
        productFlavors {
            x86 {
                flavorGroup "abi"
            }
            arm {
                flavorGroup "abi"
            }
            mips {
                flavorGroup "abi"
            }
        }

    }
}

有人可以帮助我解决这个好吗？

Can someone help me to resolve this please?

干杯，

推荐答案

由于Android的摇篮插件版本13，你现在就可以生成单独的APK的使用新的分裂的机制。你可以读到它here.

As of Android Gradle Plugin version 13 you can now generate seperate APK's using the new "split" mechanism. You can read about it here.

默认的文件结构，把你的.so文件是：

The default file structure for placing your .so files is:

src
-main
  -jniLibs
    -armeabi
      -arm.so
    -armeabi-v7a
      -armv7.so
    -x86
      -x86.so
    -mips
      -mips.so

请注意，该.so文件的名称是不重要，只要它具有的.so扩展

Note that the name of the .so file is unimportant as long as it has the .so extension.

然后在你的摇篮构建文件：

Then in your Gradle build file:

android {
...
splits {
abi {
  enable true
  reset()
  include 'x86', 'armeabi-v7a', 'mips', 'armeabi'
  universalApk false
  }
 }
}

和

// map for the version code
ext.versionCodes = ['armeabi-v7a':1, mips:2, x86:3]

import com.android.build.OutputFile

android.applicationVariants.all { variant ->
    // assign different version code for each output
    variant.outputs.each { output ->
        output.versionCodeOverride =
            project.ext.versionCodes.get(output.getFilter(OutputFile.ABI)) * 1000000 + android.defaultConfig.versionCode
    }
}

请注意，该版本codeS上面ext.version codeS在很大程度上是不相关的，这是此处添加了独特的偏移每个ABI的类型，这样的版本codeS并不冲突。

Note that the version codes above in ext.versionCodes are largely irrelevant, this is here to add a unique offset for each ABI type so version codes do not clash.
