OnResume相機錯誤..不能連接到相機服務

在我的活動中，我有3個Tabost，第一個是畫廊第二個是相機，第三個是視頻，當我點擊相機它的開放和用戶可以很容易地拍照，其工作正常和點擊另一個tabhost其他事情發生，但當我再次點擊相機，然後應用程序崩潰，它顯示錯誤「OnResume相機錯誤..不能連接到相機服務」OnResume相機錯誤..不能連接到相機服務

以下是我的簡歷代碼... 。

protected void onResume() { 
     super.onResume(); 
     // TODO Auto-generated method stub 
     if(camera==null){ 
     camera = Camera.open(); 
     camera.startPreview(); 
     camera.setErrorCallback(new ErrorCallback() { 
      public void onError(int error, Camera mcamera) { 

       camera.release(); 
       camera = Camera.open(); 
       Log.d("Camera died", "error camera"); 

      } 
     }); 
     } 
     if (camera != null) { 
      if (Build.VERSION.SDK_INT >= 14) 
       setCameraDisplayOrientation(context, 
         CameraInfo.CAMERA_FACING_BACK, camera); 
      preview.setCamera(camera); 
     } 
    }

主要在這裏示出了誤差在該線陣相機= Camera.open（）;

我試圖用相機釋放的onPause，但沒有工作..請提出好的建議

附加的logcat的錯誤 – Bhargav

請我已經更新了我的問題與logcat –

您是否在清單中爲Camera添加權限？ – shiladitya

你釋放相機的onPause？

像這樣

if (mCamera != null) { 
    // Call stopPreview() to stop updating the preview surface. 
    mCamera.stopPreview(); 

    // Important: Call release() to release the camera for use by other 
    // applications. Applications should release the camera immediately 
    // during onPause() and re-open() it during onResume()). 
    mCamera.release(); 

    mCamera = null; 
}

您必須stopPreview和你的情況，否則從第一個呼叫仍受阻resurce釋放相機...
