构建库 - 简书

1.File --> New Moudle
2.添加文件结构

3.库的build.gradle配置

plugins {
    id 'com.android.library'
}

android {
    namespace 'com.wireless.yolov5ncnn'
    compileSdk 33

    defaultConfig {
        minSdk 24
        targetSdk 33

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        consumerProguardFiles "consumer-rules.pro"
        externalNativeBuild {
            cmake {
                cppFlags ''
            }
        }
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            ndk {
                abiFilters "armeabi-v7a","arm64-v8a"
            }
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    externalNativeBuild {
        cmake {
            path file('src/main/cpp/CMakeLists.txt')
            version '3.22.1'
        }
    }
}

dependencies {

    implementation 'androidx.appcompat:appcompat:1.6.1'
    implementation 'com.google.android.material:material:1.8.0'
    testImplementation 'junit:junit:4.13.2'
    androidTestImplementation 'androidx.test.ext:junit:1.1.5'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.1'
}

task makeJar(type: Copy) {
    delete 'libs/yolov5ncnn.jar' //删除之前的旧jar包
    from('build/intermediates/aar_main_jar/release/') //这里是你要打包成jar的代码
    into('libs/') //将jar包输出到指定目录下 （我这里也不成功）
    include('classes.jar')
    rename('classes.jar', 'yolov5ncnn.jar') //自定义jar包的名字（这里我rename并不成功！）
}
makeJar.dependsOn(build)

4.执行build.gradle的makeJar任务

5.使用依赖app下的build.gradle 增加
打包文件目录

dependencies {
   implementation(fileTree("libs"))
}

混淆文件增加这个配置,防止打包编译功能不生效
