Java Android：如何读取不'；不要指定我的代码行

我的应用程序用户报告错误，导致他们的堆栈跟踪显示在Google Play开发者控制台中。但问题是，这些日志/跟踪中有几个不包含有关我的应用程序特定代码的信息。 下面是一个例子：

及

所有这些都来自三星设备。我无法在Nexus 5上重现这些错误，其他设备用户也无法报告这些问题。我怎么知道是什么原因导致了车祸

我有一个线索，但那也只发生在三星。我有以下代码：

private class ListOldFiles extends AsyncTask<String, Integer, Boolean> {
    @Override
    protected Boolean doInBackground(String... strings) {

        ArrayList<String> filesList = loadOrderedCollection(FILES_LIST_KEY);
// loads JSON from SharedPreferences and converts it into ArrayList.
        for (String path : filesList) {
            if (isCancelled())
                return false;

            itemList.add(new Item(path));
            publishProgress();
        }
        return true;
    }

    @Override
    protected void onProgressUpdate(Integer... values) {
        itemArrayAdapter.notifyDataSetChanged();
        super.onProgressUpdate(values);
    }

    @Override
    protected void onPostExecute(Boolean shouldContinue) {
        if (shouldContinue)
            listAllFiles = new ListAllFiles().execute();

        super.onPostExecute(shouldContinue);
    }
}

报告的错误是“由以下原因引起的：android.os.TransactionTooLargeException”。可能您的JSON太大，无法加载。查看有关此异常的文档了解更多信息：好的，文档中说“活页夹事务缓冲区的固定大小有限，目前为1Mb”。这是什么意思？在JSON抛出异常之前，它可以有多大？我不知道您试图实现什么，但如果JSON太大，您可能应该找到更好的方法来存储数据。也许是数据库什么的。这样，当用户滚动时，您可以请求唯一必要的信息，而不是将所有内容加载到内存中。我正在保存所有音频文件的列表，然后用保存的列表填充我的RecyclerView。在前面提到的异步任务中，我从SharedReferences获取它是的，基本上是将整个列表加载到内存中。因此，如果文件列表很长，它可能太大了。

private class ListOldFiles extends AsyncTask<String, Integer, Boolean> {
    @Override
    protected Boolean doInBackground(String... strings) {

        ArrayList<String> filesList = loadOrderedCollection(FILES_LIST_KEY);
// loads JSON from SharedPreferences and converts it into ArrayList.
        for (String path : filesList) {
            if (isCancelled())
                return false;

            itemList.add(new Item(path));
            publishProgress();
        }
        return true;
    }

    @Override
    protected void onProgressUpdate(Integer... values) {
        itemArrayAdapter.notifyDataSetChanged();
        super.onProgressUpdate(values);
    }

    @Override
    protected void onPostExecute(Boolean shouldContinue) {
        if (shouldContinue)
            listAllFiles = new ListAllFiles().execute();

        super.onPostExecute(shouldContinue);
    }
}

             listAllFiles = new ListAllFiles().execute();
