Android | gradle Flavor多渠道打包

风味维度

使用flavorDimensions定义风味维度,维度越多，能打出的渠道包越丰富。

单风味维度

defaultConfig {
    flavorDimensions "default"
}


productFlavors {
    google {
     
    }

    huawei {
        applicationIdSuffix ".huawei"
    }
}

单风味维度只能构建productFlavors 里定义的风味维度,不能组合. 如图只能构建google和huawei两种渠道包

多维风味维度

defaultConfig {
    flavorDimensions "company","channel"
}


productFlavors {
    companyA {
       dimension "company"
    }

    companyB {
        dimension "company"
    }
    
   channelA {
         dimension "channel"
    }

   channelB {
         dimension "channel"
    }
}

根据company和channel进行组合, 上述可以构建companyAchannelA , companyAchannelB, companyBchannelA , companyBchannelB 四种组合的渠道包

BuildConfig

给BuildConfig生成属性

 buildConfigField "boolean", "LOG_DEBUG", "false"
 //动态赋值url和端口
 buildConfigField('String', 'BASE_URL', '"https://www.baidu.com/"')
 buildConfigField('int', 'URL_PORT', '5672')

通过BuildConfig 判断当前flavor

通过Flavor应用插件

项目中可以有类似需求, google渠道应用'com.google.gms.google-services'插件, 而huawei渠道应用'com.huawei.agconnect'插件
可以通过判断Flavor应用对应渠道插件,代码如下

def String getCurrentFlavor() {
    Gradle gradle = getGradle()
    String tskReqStr = gradle.getStartParameter().getTaskRequests().toString()
    Pattern pattern;
    if (tskReqStr.contains("assemble"))
        pattern = Pattern.compile("assemble(\w+)(Release|Debug)")
    else
        pattern = Pattern.compile("bundle(\w+)(Release|Debug)")

    Matcher matcher = pattern.matcher(tskReqStr)

    if (matcher.find()) {
        return matcher.group(1).toLowerCase()
    } else {
        return "";
    }
}

gradle.projectsEvaluated {
    preBuild.dependsOn(applyPluginByFlavor)
}

// Then check on the parameter, which comes from the command line
task applyPluginByFlavor {
    def flavorType = ""
    flavorType = getCurrentFlavor();
    if (flavorType.equals("google")) {
        println("正在构建 google 包")
        apply plugin: 'com.google.gms.google-services'
        apply plugin: 'com.google.firebase.crashlytics'
        apply plugin: 'com.google.firebase.firebase-perf'
    }
    if (flavorType.equals("huawei")) {
        println("正在构建 huawei 包")
        apply plugin: 'com.huawei.agconnect'
        apply plugin: 'com.huawei.agconnect.apms'
    }
}

获取 MetaData 属性

// manifest占位符
 manifestPlaceholders = [
                    HW_BANNER_ID       : "xxx"
            ]
            
            
// manifest 中配置meta-data
<meta-data
            android:name="HW_BANNER_ID"
            android:value="${HW_BANNER_ID}" />

获取在gradle中配置的HW_BANNER_ID

public String getMetaData(String key) {
        try {
            PackageManager packageManager = getPackageManager();
            ApplicationInfo applicationInfo = packageManager.getApplicationInfo(this
                    .getPackageName(), PackageManager.GET_META_DATA);
            return applicationInfo.metaData.getString(key);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return "";
    }
