如何仅使用ARM目标的NDK构建基于Android Gradle的应用程序?

问题描述

我从供应商处获得了一个.so文件，该文件仅支持"arm".目前，它对我的​​Android应用程序运行正常.我想以某种方式分离使用Android Studio模块的实现，因此我可以按照本教程 https://www.youtube.com/watch?v=1i4I-Nph-Cw .

I have a .so file from vendor which only support "arm". Currently it works perfectly fine for my Android application. Somehow I want to separate the implementation using Android Studio module, so I can export the module as Jar following this tutorial https://www.youtube.com/watch?v=1i4I-Nph-Cw.

导出JAR时，构建过程返回错误

When I export the JAR, the build process returns an error

:app:linkMipsDebugRemoteDesktopSharedLibrary FAILED

FAILURE: Build failed with an exception.

日志显示gradle试图针对mips进行构建，但由于库不兼容而失败，因为我只有arm库.我的问题是如何跳过针对mips的构建过程?还是有可能只针对ARM体系结构?

The logs says that gradle was trying to build against mips but failed due the incompatible library, since I only have arm library.My question how to skip the build process against mips? Or is it possible to target ARM only architecture?

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)

推荐答案

最后我做到了.这是禁用特定任务的示例.将此行添加到您的build.gradle

Finally I made it.Here's an example to disable specific task.Add this line on your build.gradle

tasks.getByPath(":app:linkMipsDebugRemoteDesktopSharedLibrary").enabled = false
