Android开发:java程序调用linux命令(高级)

    DefyPrcHelper国行2.3.4ROM小问题修复工具

    最近手机升级到了2.3.4(moto大发慈悲);用着还好,但是也有些用户体验不好的地方,比如相机不能静音,(我邪恶了?),键盘灯太亮等等,故此 做 了这个小应用.

    主要软件功能:

   +消除恢复照相机摄像机声音

   +去除创建联系人以外崩溃的Bug(当然如果遇到其他问题,实际是disable "BlurContactsSync.apk";

   +直接没有发现引起其他问题,如果用户发现也可以点击恢复按钮恢复)

   +开启.关闭键盘灯
