自动删除未对齐的 apk

如果你不需要使用 unaligned 后缀（你可能没有）自动生成的 apk 文件，你可以将以下代码添加到 build.gradle 文件中：

// delete unaligned files
android.applicationVariants.all { variant ->
  variant.assemble.doLast {
    variant.outputs.each { output ->
        println "aligned " + output.outputFile
        println "unaligned " + output.packageApplication.outputFile

        File unaligned = output.packageApplication.outputFile;
        File aligned = output.outputFile
        if (!unaligned.getName().equalsIgnoreCase(aligned.getName())) {
            println "deleting " + unaligned.getName()
            unaligned.delete()
        }
    }
  }
}

从这里开始
