moto-razr记录器问题

我是一名学生，在做我的Android应用程序任务。我遇到了一个我无法解决的问题。请给我一些建议，thx。我想要有一个视频录制的活动，并且我已经完成了使用此代码。 Video recording with media recorder 这里是我的代码，它做工精细的其他手机，但它并没有在MOTO-RAZR 做工精细这里有两个视频通过HTC渴望和MOTO RAZR服用。愿望：http://youtu.be/suPF9Hk6iYk RAZR：http://youtu.be/wLvH7SXdcIs 任何一个可以帮助我解决我的问题？moto-razr记录器问题

我认为这个问题是一个安全问题：

您需要设置记录预览，否则有些设备会认为这是一个安全漏洞，用于捕获视频，而无需在屏幕上显示您的捕获/预览。尝试添加到您的记录器设置：

. 
. 
recorder.setPreviewDisplay(mHolder.getSurface()); 
. 
.
