我试图从我的应用程序中读取一个CSV文件，代码在Android 5.1以下完美地工作，但在我的Android 10手机上不工作。
这是在logcat上抛出的异常。

我在这里得到一个异常
CSVReader dataRead = new CSVReader(new FileReader(file));
这是文件选取器。
Intent pickerIntent = mDriveServiceHelper.createFilePickerIntent();
pickerIntent.addCategory(Intent.CATEGORY_OPENABLE);
pickerIntent.setAction(Intent.ACTION_GET_CONTENT);
pickerIntent.setType("*/*");
// The result of the SAF Intent is handled in onActivityResult.
startActivityForResult(pickerIntent, REQUEST_CODE_OPEN_DOCUMENT);
