[移动开发]安卓 - gradle中动态参数设置

1. 在安卓中对release和debug打包的app设置不同的图标和应用名

2. 设置打包时的名称（加上版本号和渠道等）

同理可以设置一些动态的变量在gradle中，然后让程序打包时自行 取值

示例1

release {
            debuggable false
            //混淆编译
            minifyEnabled true
            zipAlignEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            buildConfigField "boolean", "ENV_SETTING", "true"
            buildConfigField("boolean", "isAppCheckUpdate", "true")
            buildConfigField("Boolean", "isModule4SubApp", String.valueOf(rootProject.ext.isModule))
            resValue "string", "app_name", "xxxx_release"
            buildConfigField("Boolean", "isModule4SubApp", String.valueOf(rootProject.ext.isModule))
        }

示例2

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            // signingConfig signingConfigs.config

            android.applicationVariants.all { variant ->
                variant.outputs.all {
                    outputFileName = "weatherspeaker_v${defaultConfig.versionName}.apk"
                }
            }
            manifestPlaceholders = [
                    app_icon: "@mipmap/ic_launcher2",
                    app_name: "@string/app_name"
            ]
        }

        debug  {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            // signingConfig signingConfigs.config

            android.applicationVariants.all { variant ->
                variant.outputs.all {
                    outputFileName = "weatherspeaker_v${defaultConfig.versionName}_debug.apk"
                }
            }
            manifestPlaceholders = [
                    
                    app_icon: "@mipmap/ic_launcher_debug",
                    app_name: "@string/app_name_debug"
            ]
        }
    }

在manifest中设置

<application
        android:name=".App"
        android:allowBackup="true"
        android:icon="${app_icon}"
        android:label="${app_name}"
        android:roundIcon="${app_icon}"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
