moto-razr記錄器問題

我是一名學生，在做我的Android應用程序任務。我遇到了一個我無法解決的問題。請給我一些建議，thx。我想要有一個視頻錄製的活動，並且我已經完成了使用此代碼。 Video recording with media recorder 這裏是我的代碼，它做工精細的其他手機，但它並沒有在MOTO-RAZR 做工精細這裏有兩個視頻通過HTC渴望和MOTO RAZR服用。願望：http://youtu.be/suPF9Hk6iYk RAZR：http://youtu.be/wLvH7SXdcIs 任何一個可以幫助我解決我的問題？moto-razr記錄器問題

我認爲這個問題是一個安全問題：

您需要設置記錄預覽，否則有些設備會認爲這是一個安全漏洞，用於捕獲視頻，而無需在屏幕上顯示您的捕獲/預覽。嘗試添加到您的記錄器設置：

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