一个完整的Android项目，首先进入界面输入账户密码进行登陆，若登陆账号没注册过则先进行保存，并提示保存成功否则提示登陆成功。(A complete Android project, first enter the interface to enter the account password for login, if the login account has not been registered, save it first, and prompt the successful save or prompt the successful login.)

代码打开摄像头，通过存储映射的方式获得一帧的buffer、并且之后不断用新产生的帧数据更新该buffer；buffer又通过共享存储的方式（最快的IPC通信），共享给其他进程获取buffer帧数据。该代码的目的主要是应对在android上不能同时打开摄像头两次的弊端，该代码相当于给视频帧数据分流的作用。

Android 实现的自定义CircleProgress 圆形、圆环进度条实例源码，本源码一共演示了7种实心、圆环形的进度条，单击按钮可看到运行时的效果。 　　进度条风格样式的设置：0空心，1实心，2实心从下到上。另外还有圆环进度，进度条中间的进度显示文字可自定义颜色和大小，我们需要根据字体的宽度设置在圆环中间，中间的进度百分比，先转换成float在进行除法运算，不然都为0，设置进度时，由于考虑多线的问题，需要同步刷新界面调用postInvalidate()能在非UI线程刷新。 　　本源码中的注释丰富，可让你学会如何制作类似的圆心、圆形的Android进度条，源码完整可编译。
