在我的 public void onActivityResult(int requestCode, int resultCode, Intent data) {......有这样的一部分：
if (requestCode == 1) {
// Make sure the request was successful
final Uri videoUri = data.getData();
MediaMetadataRetriever retriever = new MediaMetadataRetriever();
//use one of overloaded setDataSource() functions to set your data source
retriever.setDataSource(getActivity(), videoUri);
String time = retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
timeInMillisec = Long.parseLong(time );
retriever.release();
在这里，我试图获取视频持续时间MediaMetadataRetriever并将其存储在 中timeInMillisec，接下来我将检查timeInMillisec任何错误的值：
Toast.makeText(getActivity(), (int) timeInMillisec, Toast.LENGTH_SHORT).show();
关键是，这里我有这个例外：
