이 문제를 해결할 수 있습니까? –

당신이 당신의 코드에서이 줄을 추가 했습니까?

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

또한 권한이 필요합니다

<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 : 미디어 레코더에서 내 비디오 코드를 기록하는 코드는 다음과 같습니다. 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 갔지 (CamcorderProfile.QUALITY_HIGH); \t \t mediaRecorder.setProfile (camcorderProfile_HQ); \t \t mediaRecorder.setOutputFile ("/ sdcard/myvideo.mp4"); \t \t mediaRecorder.setMaxDuration (60000); // 최대 지속 시간을 60 초로 설정합니다. \t \t mediaRecorder.setMaxFileSize (5000000); // 최대 파일 크기를 설정하십시오. 5M –

이 문제가 안드로이드 매니페스트에 제공되지 권한이 될 것으로 보인다. 우리는 매니 페스트에서 권한을 확인해야합니다

다음과 같은 사용 권한을 자신의 매니 페스트에서 사용하세요

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

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