两次连续点击录制按钮时的强制退出

解决方法:

原因:调用MediaRecorder的start()与stop()间隔不能小于1秒(有时候大于1秒也崩)，否则程序必出现崩溃。

在stop()和start()方法中各自抛出异常.

在魅族手机中点击录制视频时异常退出;

解决方法:

这个错误是和调用相机摄像头相关的。

一.产生这个错误的原因主要在于代码控制分辨率的显示和真机测试分辨率不一样。

WindowManager wm = (WindowManager)getSystemService(Context.WINDOW_SERVICE);

Display display = wm.getDefaultDisplay();

Camera.Parameters parameters = camera.getParameters();//得到摄像头的参数

parameters.setPreviewSize(display.getWidth(),display.getHeight());注释掉这两句

parameters.setPictureSize(display.getHeight(),display.getWidth());注释掉这两句

二：有可能你的真机是属于定制机，或者深度开发过，对camera对了不少的改动。

camera.setParameters(parameters);//导致不能使用这个方法了，注释掉这一行吧。
