我在片段代码中的应用程序的简历上崩溃了.我自己从未见过这次崩溃,但我通过TestFlight收到了用户的崩溃报告.我猜有些东西我不知道,因为代码在大多数机器上工作正常.任何帮助将不胜感激.

这是调用堆栈.

我已经阅读了很多关于这个问题的问题.有些类似于我所经历的; 我没有成功地尝试了答案.该代码适用于HTC Android 4.2,不适用于Nexus 7 Android 4.4.我已经修改了存储目录以在android 4.4上工作,所以这不是问题.

如果我使用相机意图永远不会返回

takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));

如果我使用,它会返回

takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoFile);

但它不保存文件.

这是完整的代码.调用意图

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(manager) != null)
{
    try
    {
        final File photoFile = createImageFile();

        if (photoFile != null)
        {
            takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
            //takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoFile);
            startActivityForResult(takePictureIntent, 1);
        }
    }
    catch (IOException e)
    {
        e.printStackTrace();
    }
}

文件名

private File createImageFile() throws IOException
{
    if (mStorageDirectory == null)
    {
        createInitialStorageDirectory();
        setupFolders();
        mScrollList.notifyDataSetInvalidated();
    }

    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new …

从我可以收集的程序已被放入后台Application Stop已被调用.应用程序返回到forground,这是发生错误的时候.该应用程序因任何原因无法加载xml文件,每次在我的手机HTC Desire One上运行代码和xml.有什么明显的东西我可以解决这个问题,或者有关如何追踪这个问题的任何建议？

这是我从TestFlight返回的调用堆栈.
