解鎖手機後Android相機預覽停止

Question

我有一個Android項目的問題，我們的相機預覽停止，但只有在手機已被鎖定然後解鎖後，它也無法拍照，這個問題有我真誠地難倒我一直無法找到在互聯網這個錯誤的任何信息，似乎做什麼都教程/其他堆棧溢出問題狀態：

@Override 
protected void onResume() { 
    super.onResume(); 
    mPreview.setVisibility(View.VISIBLE); 
    //Open the default i.e. the first rear facing camera. 
    mCamera = Camera.open(); 
    try{ 
     mCamera.reconnect(); 
    } catch(Exception ex) { 
    } 
    mCamera.startPreview(); 
    cameraCurrentlyLocked = defaultCameraId; 
    mPreview.setCamera(mCamera); 
} 

@Override 
protected void onPause() { 
    super.onPause(); 
    mPreview.setVisibility(View.GONE); 
    //Because the Camera object is a shared resource, it's very 
    //Important to release it when the activity is paused. 
    if (mCamera != null) { 
     mPreview.setCamera(null); 
     mCamera.stopPreview(); 
     mCamera.release(); 
     mCamera = null; 
    } 
} 

而且錯誤（在拍攝照片）如下：

任何幫助是非常讚賞。

我前幾天面臨同樣的問題...嘗試：從在FrameLayout裏取出的onPause預覽和的onResume再次添加它..
