Kuix在魅族上的安装

    今天第一次在一台魅族上安装我的程序，结果不管是签名还是未签名的程序，安装都失败，魅族手机没有预装java虚拟机，一开始用的是手机主人装的一款“辰元”的虚拟机，安装后启动报javax/microedition/io/file/FileSystemRegistry的错误，估计是不支持文件操作，试了安装jbed，安装成功，但是没有增加图标，到安装目录下启动程序失败，估计不兼容。用了网上另外一个多文章介绍的J9jvm，同样无法安装，令人哭笑不得的是，这个虚拟机明显不是用在魅族上的，那分辨率叫大，估计用个牙签都不容易点到，更何况魅族只能用手指点，有点大象脚踩蚂蚁的感觉，戳得我快吐血了。山寨就是山寨阿，什么支持国产机之类的就是个噱头。我想起年初老婆卖的朵唯手机，2000大洋，典型的金玉其外败絮其中的作品，java程序超过500K都不让安装，分辨率超低，最让人吐血的是不管你在做什么，一点红色的结束通话键一律强制结束。

XT800常用的一些设置
1、如何在XT800上安装软件？
1)将装有SD卡的XT800通过数据线连接电脑
2)将.apk格式的软件，放在SD卡上
3)在程序菜单中找到“文件管理器”并点击.apk格式的软件

2、如何删除已安装的软件？
菜单—设置—应用程序—管理应用程序—长按需要删除的程序—卸载，即可删除相应软件

3、下载的软件，无法安装，提示为第三方软件，不允许安装！
菜单-设置-应用程序，把第一项的未知来源勾选就可以了


3、为何手机连接电脑后不能同步数据，
USB连接时,选择“内存卡管理”
进入“设置”-“应用程序”-“开发”-消除“USB调式”。因为打开USB调式后，手机连接电脑就不能访问内存卡

4、如何关闭上网功能？
菜单-双模双待设置-默认数据网络-禁用，即可关闭网络，但不影响打电话、收短信、彩信

5、下载的APK文件，为什么安装后不能打开，强行关闭？
1)安装后最好不要直接按“打开”，要选择“完成”不然很容易破坏程序
2)因为有些软件不匹配，无法使用，如果发现不能打开强行关闭的软件，请在程序管理器内卸载该程序

6、如何在XT800上打开USB调试？
设置—应用程序—开发——勾选USB调试
