Android Intent和OnActivityResult导致活动以实际方式重新启动：需要解决此问题

我有20个imageview，我有20个按钮，当我点击任何1个按钮时，它给我选择gallery或camera中的图像的选项，当我选择任何选项时，例如gallery，它将带我到gallery，让我从他们中选择图像，并让我在imageview中显示相应按钮的图像 现在的问题是，有时当我执行上述整个过程时，我的活动会自动重新启动，所有首先选择的图像都会从其imageview中消失 参考我的代码如下：

    @Override
         public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
           setContentView(R.layout.new_upload);

      // *****************Assigning Button variable their Id declare in XML

看起来活动正在重新创建。 尝试将以下内容添加到清单中的活动条目中

---

android:configChanges=orientation | keyboard隐藏的android:launchMode=singleTask

问题可能是由于内存利用率。尝试使用内存分析器工具测试代码，以便识别问题

---

如果您在活动重新创建期间发布日志语句，我可以更好地帮助您。

请清理您的代码，因为现在很难理解它。@Orlmye感谢您的回复。。。。我已经按照您的要求编辑了代码。因此，现在请检查我的代码，您是否可以让我知道为什么会出现错误…还想添加一些我在对其进行更多测试时发现的详细信息。1在模拟器上测试时不会出现问题，而是在尝试在android中选择图像时出现的问题手机版本2.3.4设备名称三星galaxy ace 2当我已经从我的多媒体资料中选择了15张图片，然后我尝试选择图片时，问题就会出现。3由于我正在使用我的设备，我没有得到相同的正确日志@不知道为什么会发生这样的错误。我一直试图使用日志，但没有用。请帮助发布您的xml文件，以便我们可以尝试在endhi user623517进行测试。您能告诉我如何将我的所有文件发送给您，因为堆栈中不允许这样做吗发布更大的代码，而且由于这个限制，我发布的代码被缩短了。这里还有一件事要加起来，那就是在经历了所有事情之后，我发现了以下几件事。1当我在emulator上进行测试时，问题不会出现。当我尝试在android手机版本2.3.4设备名三星galaxy ace中选择图像时，问题会出现。2当我已经从我的图库中选择了15个图像，然后我尝试选择图像时，问题会出现。3由于我使用的是我的设备，所以我没有得到相同的正确日志@不知道为什么会发生这样的错误。我一直试图使用日志，但没有用。请帮助在设备上运行日志时，您可以发布日志输出吗？我认为改变启动模式没有帮助？发布日志输出。根据您的需要，我已经添加了我的日志，当我运行我的应用程序并将错误输入我的手机时，我会得到日志
