Android动态配置ApplicationId，App名字，AppLogo

需求：同一套代码，打一个京东，腾讯，小米的包，logo都是对应公司的logo，App名字为：京东，腾讯，小米
一、打开项目，在src目录下，与main同级的地方，将要打的包新建三个文件夹，分别以jingdong，tengxun，xiaomi命名，在这三个文件夹下面就放着和其他两个App不同的东西，比如logo图片，App名字等，结构如图：

strings.xml 文件

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">小米</string>
</resources>

styles.xml 文件

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar">
        <!-- Show a splash screen on the activity. Automatically removed when
             Flutter draws its first frame -->
        <item name="android:windowBackground">@drawable/launch_background</item>
    </style>
</resources>

 

二、文件路径app ==> src ==> main ==> AndroidManifest.xml 文件配置

<application
    android:label="@string/app_name"
    android:icon="@mipmap/ic_launcher"
    android:roundIcon="@mipmap/ic_launcher"
    android:theme="@style/LaunchTheme"
    tools:replace="android:allowBackup,icon,theme,label">
    ...

</application>

三、对App 的build.gradle(android ==> app ==> build.gradle)进行配置，其中主要是productFlavors的配置，

注意点：

flavorDimensions "default"

//不同APP的配置
productFlavors {
    //TODO:....
}

配置如下

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

//打包时间
def releaseTime() {
    return new Date().format("yyyyMMddHHmm")
}

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    flavorDimensions "default"
    signingConfigs {
        debug {
            storeFile file('AndroidKeyStore')
            storePassword '1234567'
            keyAlias = 'keyforproject'
            keyPassword '123456'
        }
        release {
            storeFile file('AndroidKeyStore')
            storePassword '1234567'
            keyAlias = 'keyforproject'
            keyPassword '123456'
        }
    }

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    lintOptions {
        disable 'InvalidPackage'
    }

    //APP默认配置

            abiFilters 'armeabi', 'armeabi-v7a', 'x86', 'x86_64', 'mips', 'mips64', 'arm64-v8a'
        }

        manifestPlaceholders = [
                JPUSH_PKGNAME : applicationId,
                JPUSH_APPKEY : "appkey", // NOTE: JPush 上注册的包名对应的 Appkey.
