MediaMetadataRetriever giving RunTimeException

Question

在我的 public void onActivityResult(int requestCode, int resultCode, Intent data) {中...有这样的部分：

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，我试图使用MediaMetadataRetriever获取视频持续时间并将其存储在timeInMillisec中，接下来，我将检查timeInMillisec的值是否有任何错误：

Toast.makeText(getActivity(), (int) timeInMillisec, Toast.LENGTH_SHORT).show();

重点是，在这里我有一个例外：

我无法弄清楚这里有什么问题。任何帮助将不胜感激。

这是堆栈跟踪的重要部分：

Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x37c3f
    at android.content.res.Resources.getText(Resources.java:351)
    at android.content.res.MiuiResources.getText(MiuiResources.java:97)
    at android.widget.Toast.makeText(Toast.java:285)
    at com.example.zub.videoplay.onActivityResult(PostFragment.java:293)
    at android.support.v4.app.FragmentActivity.onActivityResult(FragmentActivity.java:151)
    at com.example.zub.videoplay.HomeActivity.onActivityResult(HomeActivity.java:586)

看起来像HomeActivity.onActivityResult，您正在尝试通过Toast显示一个不存在的字符串（ID＃0x37c3f）。
