MediaRecorder示例不起作用

我下載了這個示例http://developer.android.com/samples/MediaRecorder/index.html但它不起作用（在htc one v 4.0.3上測試過）。MediaRecorder示例不起作用

可以解決這個問題嗎？ –

您添加代碼中的這條線？

MediaRecorder mediaRecorder = new MediaRecorder(); 
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT); 
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT); 
CamcorderProfile camcorderProfile_HQ = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH); 
mediaRecorder.setProfile(camcorderProfile_HQ); 
mediaRecorder.setOutputFile("/sdcard/myvideo.mp4"); 
mediaRecorder.setMaxDuration(60000); // Set max duration 60 sec. 
mediaRecorder.setMaxFileSize(5000000); // Set max file size 5M

還需要的權限：

<uses-feature android:name="android.hardware.camera" /> 
<uses-permission android:name="android.permission.RECORD_AUDIO" /> 
<uses-permission android:name="android.permission.CAMERA" /> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

@sinigami：我的媒體錄像機的代碼片段錄製視頻如下：mediaRecorder = new MediaRecorder（）; \t \t mediaRecorder.setAudioSource（MediaRecorder.AudioSource.DEFAULT）; \t \t mediaRecorder.setVideoSource（MediaRecorder.VideoSource.DEFAULT）; \t \t CamcorderProfile camcorderProfile_HQ = CamcorderProfile \t \t \t \t獲得（CamcorderProfile.QUALITY_HIGH）; \t \t mediaRecorder.setProfile（camcorderProfile_HQ）; \t \t mediaRecorder.setOutputFile（「/ sdcard/myvideo.mp4」）; \t \t mediaRecorder.setMaxDuration（60000）; //設置最大持續時間60秒。 \t \t mediaRecorder.setMaxFileSize（5000000）; //設置最大文件大小5M –

對於答案很好解釋+1，請張貼這些行作爲答案，它會更有用！ –

好的...我正在編輯我的答案，然後 –

這些行添加到您的AndroidManifest.xml：`

<uses-permission 
    android:name="android.permission.RECORD_AUDIO" />

這個問題似乎是在Android清單未提供許可。我們需要確保清單中的權限

在您的清單中使用以下權限

<uses-permission android:name="android.permission.CAMERA" /> 
<uses-feature android:name="android.hardware.camera" /> 

<uses-permission android:name="android.permission.RECORD_AUDIO" /> 

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
