相機在Android應用上死機

我目前正在嘗試將相機集成到我的android應用中，並將照片保存在我的設備上;然而，當我拍照時，我無法繼續進行（應用程序有效，但相機拍攝凍結，意味着我可以拍攝另一張照片並返回，但無法確認）。我想知道你們是否可以提供幫助。請儘可能簡單地解釋這一點，因爲我對android編程非常新穎。感謝大家！相機在Android應用上死機

public class PhotoCapture extends Activity { 
int TAKE_PHOTO_CODE = 0; 
public static int count=0; 
public static File newfile; 
@Override 
public void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.photocapture); 



Button capture = (Button) findViewById(R.id.takepicture); 
capture.setOnClickListener(new View.OnClickListener() { 
    public void onClick(View v) { 

     ContextWrapper cw = new ContextWrapper(getBaseContext()); 
     newfile = cw.getDir("test.jpg", Context.MODE_PRIVATE); 

     try { 
      newfile.createNewFile(); 
     } catch (IOException e) {}  

     Uri outputFileUri = Uri.fromFile(newfile); 


     Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
     cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri); 

     startActivityForResult(cameraIntent, TAKE_PHOTO_CODE); 
    } 
}); 
} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 

    if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) { 


     uri = data.getData().toString(); 
     Log.d("CameraDemo", "Pic saved"); 

     Intent myview = new Intent(this, Finalpiece.class); 
     startActivity(myview); 


    } 
} 
}

似乎onActivityResult沒有運行:( – user2309668 2013-04-23 03:47:22

參考這裏： http://stackoverflow.com/questions/15248265/camera-intent-not-working-with-samsung-galaxy-s3/15287164#15287164 – Skynet 2013-04-23 04:05:18

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

使用此權限，然後......

private static final int REQ_CAPTURE_CAPTURE__IMAGE = 0; 
    private String imagePath; 

/** 
    * Start camera activity. 
    */ 
    protected void startCameraActivity() { 
     String imageDirectory = Environment.getExternalStorageDirectory() 
     + File.separator + "surbeyImg"; 
     File imageDirectory = new File(imageDirectory); 

     if (!(imageDirectory.exists())) { 
      imageDirectory.mkdir(); 
     } 

     String imagePath = imageDirectory + File.separator + imgName+".jpg"); 

     File file = new File(imagePath); 
     Uri outputFileUri = Uri.fromFile(file); 

     Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 

     intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri); 
     intent.putExtra("outputFormat", Bitmap.CompressFormat.PNG.toString()); 
     startActivityForResult(intent, REQ_CAPTURE_CAPTURE__IMAGE); 
    } 

    protected void onActivityResult(int requestCode, int resultCode, 
      Intent imageReturnedIntent) { 

     switch (requestCode) { 

     case REQ_CAPTURE_CAPTURE__IMAGE: 

      if (resultCode == RESULT_OK) { 
       Intent intentImg = new Intent(CameraDemo.this, ShowImg.class);    
       intentImg.putExtra("imagePath",imagePath);   
       startActivity(intentImg); 

      } 

      break; 

     default: 
      break; 

     } 
    }

這個使用這個代碼後...感謝
