Android 如何自定义apk打包的包名

今天插播一篇文章,如何通过Android Studio自定义我们打包的apk文件名.
找到你App的build.gradle文件,不是根目录的Build.gradle
如下图:
在android 标签中添加如下代码

    //修改apk 的 文件名    applicationVariants.all { variant ->        variant.outputs.all { output ->            def date = new Date().format("yyyy_MM_dd_hh_mm", TimeZone.getTimeZone("GMT+08"))            if (variant.buildType.name == "debug") {                output.outputFileName = "${date}_arbitrator_v${android.defaultConfig.versionName}_debug_${android.defaultConfig.versionCode}.apk"            } else if (variant.buildType.name == "release") {                output.outputFileName = "${date}_arbitrator_v${android.defaultConfig.versionName}_release_${android.defaultConfig.versionCode}.apk"            }        }    }

怕有些小伙伴找不到应该在哪里添加,我现在把完整的代码贴上

apply plugin: 'com.android.application'android {    compileSdkVersion 28    defaultConfig {        applicationId "com.zz.democostomview"        minSdkVersion 21        targetSdkVersion 28        versionCode 1        versionName "1.0"        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"    }    buildTypes {        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'        }    }    //修改apk 的 文件名    applicationVariants.all { variant ->        variant.outputs.all { output ->            def date = new Date().format("yyyy_MM_dd_hh_mm", TimeZone.getTimeZone("GMT+08"))            if (variant.buildType.name == "debug") {                output.outputFileName = "${date}_arbitrator_v${android.defaultConfig.versionName}_debug_${android.defaultConfig.versionCode}.apk"            } else if (variant.buildType.name == "release") {                output.outputFileName = "${date}_arbitrator_v${android.defaultConfig.versionName}_release_${android.defaultConfig.versionCode}.apk"            }        }    }}dependencies {    implementation fileTree(dir: 'libs', include: ['*.jar'])    implementation 'androidx.appcompat:appcompat:1.0.2'    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'    testImplementation 'junit:junit:4.12'    androidTestImplementation 'androidx.test:runner:1.1.1'    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'}
