Android studio 打包apk如何重命名apk名称

在打包签名之前，在相应的module的build.gradle中添加如下代码

<pre name="code" class="java">    applicationVariants.all { variant ->        variant.outputs.each { output ->            def oldFile = output.outputFile            def newName = 'luckpan';            if (variant.buildType.name.equals('release')) {//                println(variant.productFlavors[0].name)                def releaseApkName = 'study-' + defaultConfig.versionName + '-luckpan.apk'                output.outputFile = new File(oldFile.parent, releaseApkName)            }            if (variant.buildType.name.equals('beta')) {                newName = oldFile.name.replace(".apk", "-v" + defaultConfig.versionName + "-build" + getDate() + ".apk")                output.outputFile = new File(oldFile.parent, newName)            }            if (variant.buildType.name.equals('debug')) {            }        }    }
