添加权限

<!-- 允许应用程序写数据到外部存储设备（主要是SD卡） -->  <uses-permission androID:name="androID.permission.WRITE_EXTERNAL_STORAGE" />  <uses-permission androID:name="androID.permission.READ_EXTERNAL_STORAGE" />  <!-- 在sdcard中创建/删除文件的权限 -->  <uses-permission androID:name="androID.permission.MOUNT_UNMOUNT_fileSYstemS" />

在具体的场景中测试一下

ZipUtils.UnZipFolder(AppConfig.DOWNLOAD_PATH + info.getfilename(),AppConfig.UNZIP_PATH);

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持编程小技巧。
