android - android YouTube使用意图上传

Intent intent = new Intent();

intent.setAction(Intent.ACTION_SEND);
intent.setType("video/3gpp");
intent.putExtra(Intent.EXTRA_STREAM, videoURI);
startActivity(Intent.createChooser(intent,"Upload video via:"));

我用上面的代码把3GP视频上传到YouTube上
但它引发了以下异常。
我不明白日期异常和媒体上传之间的关系

最佳答案

当我使用Uri.fromFile()获取视频的uri时，遇到了同样的错误。解决方案是使用ContentProvider创建uri：

ContentValues content = new ContentValues(4);
content.put(Video.VideoColumns.TITLE, "Test");
content.put(Video.VideoColumns.DATE_ADDED,
System.currentTimeMillis() / 1000);
content.put(Video.Media.MIME_TYPE, "video/mp4");
content.put(MediaStore.Video.Media.DATA, "/sdcard/myvideo.mp4");
ContentResolver resolver = getContext().getContentResolver();
Uri uri = resolver.insert(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, content);
