Question

我有一个看起来很疯狂的错误???

我从我的活动中开始片段。

在片段中，我调用startActivityForResult，尝试从图库中获取图像。

Intent intent = new Intent();
intent.setType("image/*"); 
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Image"), SELECT_IMAGE);

当我从画廊回来时，我的应用程序崩溃了。我跟着这个问题，我看到当我回到我的活动时，我看到我的片段的onCreate()再次被启动。我不明白为什么我的片段是在另一次创建的，我的webservice对象被删除了。

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);   
    // TODO: Bug mWebServicesManager.getEditingBlogItem() return null sometimes, only when i open first time get image from galerie

    Log.i("EditImageSectionFragment","mWebServicesManager.getEditingBlogItem() ="+mWebServicesManager.getEditingBlogItem());    
    mSection = (ImagesSection) mWebServicesManager.getEditingBlogItem().getSections().get(mSectionPosition);
}

当我在HTC mobile上运行测试时，一切正常，我没有得到这个bug。但是当我在我的Nexus S（Android 4.1）上运行应用程序时，当我尝试获取图像时它总是会崩溃。

我想知道为什么我的片段又被创建了？为什么我的webServiceManager对象被删除了？
