使用意图的android youtube上传

Question

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:"));

我使用上面的代码通过触发意图将 3gp 视频上传到 youtube

但它会引发以下异常。

我不明白日期异常和媒体上传有什么关系

Answer 1

当我使用Uri.fromFile() 获取视频的 URI 时，我遇到了同样的错误。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);
