Android的記錄視頻

Question

我有這個問題讓我的adnroid程序工作。我有這個作爲我record.java代碼

import java.io.IOException; 



import android.app.Activity; 
import android.content.Intent; 
import android.content.pm.ActivityInfo; 
import android.media.CamcorderProfile; 
import android.media.MediaRecorder; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.MenuInflater; 
import android.view.MenuItem; 
import android.view.Surface; 
import android.view.SurfaceHolder; 
import android.view.SurfaceHolder.Callback; 
import android.view.SurfaceView; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Toast; 

public class record extends Activity{ 

    MediaRecorder recorder; 
    SurfaceHolder holder; 
    boolean recording = false; 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 

     recorder = new MediaRecorder(); 
     initRecorder(); 
     setContentView(R.layout.view); 

     SurfaceView cameraView = (SurfaceView) findViewById(R.id.sView); 
     holder = cameraView.getHolder(); 
     holder.addCallback((Callback) this); 
     holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); 

     cameraView.setClickable(true); 
     cameraView.setOnClickListener((OnClickListener) this); 
    } 

    private void initRecorder() { 
     recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT); 
     recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT); 

     CamcorderProfile cpHigh = CamcorderProfile 
       .get(CamcorderProfile.QUALITY_HIGH); 
     recorder.setProfile(cpHigh); 
     recorder.setOutputFile("/sdcard/videocapture_example.mpg"); 
     recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); 
     recorder.setMaxDuration(60000); // 60 seconds 
     recorder.setMaxFileSize(100000000);// Approximately 10 megabytes 
     recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP); 


    } 


    private void prepareRecorder() { 
     recorder.setPreviewDisplay(holder.getSurface()); 

     try { 
      recorder.prepare(); 
     } catch (IllegalStateException e) { 
      e.printStackTrace(); 
      finish(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
      finish(); 
     } 
    } 

    public void onClick(View v) { 
     if (recording) { 
      recorder.stop(); 
      recording = false; 

      // Let's initRecorder so we can record again 
      initRecorder(); 
      prepareRecorder(); 
     } else { 
      recording = true; 
      recorder.start(); 
     } 
    } 

    public void surfaceCreated(SurfaceHolder holder) { 
     prepareRecorder(); 
    } 

    public void surfaceChanged(SurfaceHolder holder, int format, int width, 
      int height) { 
    } 

    public void surfaceDestroyed(SurfaceHolder holder) { 
     if (recording) { 
      recorder.stop(); 
      recording = false; 
     } 
     recorder.release(); 
     finish(); 

    } 

我的Android清單看起來是這樣的，以及

 <activity android:name=".record" 
       android:label="@string/app_name"> 
     <intent-filter> 
      <action android:name="com.apapa.ttt.RECORD" /> 

     </intent-filter> 
     </activity> 

</application> 


<uses-sdk android:minSdkVersion="8" /> 
<uses-permission android:name="android.permission.CAMERA" /> 
<uses-permission android:name="android.permission.RECORD_VIDEO"/> 
<uses-feature android:name="android.hardware.camera"/> 
<uses-feature android:name="android.hardware.camera.autofocus"/> 
<uses-permission android:name="android.permission.record_audio"/> 

如何過，當我運行這段代碼總是帶來出現錯誤「應用程序意外停止，請再試一次」我真的很困惑我在這裏做錯了什麼，因爲我認爲我的每一步都是正確的。任何幫助都感激不盡。

Answer 1

android.permission.RECORD_VIDEO它不存在。

檢查文件是否被創建？或分別創建文件。
