[移动开发]安卓项目构建时会有（WARNING: API ‘variantOutput.getPackageApplication()‘ is obsolete and has been replace）提示

在gradle3.2.0以前，重命名apk打包名称使用defaultConfig.versionCode或者defaultConfig.versionName写法，如下所示：

//输出的为渠道包的名字，例如 xiaomi.apk
applicationVariants.all { variant ->
  variant.outputs.each { output ->
  def outFile = output.outputFile
   if (outFile != null && outFile.name.endsWith(".apk")) {
        def fileName = "中国蓝_${defaultConfig.versionCode}_${defaultConfig.versionName}}.apk"
         output.outputFile = new File(outFile.parent, fileName)
    }
  }

}

而在gradle3.2.0之后，再使用以前的写法的话，项目构建时则会有如下提示：

WARNING: API 'variantOutput.getPackageApplication()' is obsolete and has been replaced with 'variant.getPackageApplicationProvider()'.
It will be removed at the end of 2019.
For more information, see?https://d.android.com/r/tools/task-configuration-avoidance.
To determine what is calling variantOutput.getPackageApplication(), use -Pandroid.debug.obsoleteApi=true on the command line to display a stack trace.
Affected Modules: app

需将defaultConfig替换为variant，以下为修改后的写法：

//输出的为渠道包的名字，例如 xiaomi.apk
applicationVariants.all { variant ->
   variant.outputs.all { output ->                                                                            
     outputFileName="中国蓝_${variant.versionCode}_${variant.versionName}}.apk"
   }

}
