一次构建同时生成32位和64位的包

1.修改app的build.gradle文件

//多平台apk
productFlavors {
    aaqianfanyidong32{
        dimension "default"
        applicationId = "com.qianfanyidong.forum"
        versionCode 23231
        versionName "5.0.9"
        signingConfig signingConfigs.aaqianfanyidong
        minSdkVersion 21
        ndk{
            abiFilters 'armeabi-v7a'
        }
    }
    aaqianfanyidong64{
        dimension "default"
        applicationId = "com.qianfanyidong.forum"
        versionCode 23231
        versionName "5.0.9"
        signingConfig signingConfigs.aaqianfanyidong
        minSdkVersion 21
        ndk{
            abiFilters 'armeabi-v8a'
        }
    }
}
复制代码

因我们项目比较特殊修改productFlavors下内容后，对应文件夹名称也需修改，否则build会找不到资源文件

完整代码如下：

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'

    }

    }

    //mark-sign

2.构建

3.分析

构建结束后可以分析下apk是不是正确的，可以使用Android studio中工具

然后选择目标apk看下lib文件夹下是不是对应32或64位的
