Question

在我的应用程序中，有一个功能，用户可以与自己选择的应用程序共享视频。代码非常简单（其中mediaPath是String类型的变量，是有效视频的路径）：

File media = new File(mediaPath);
Uri uri = FileProvider.getUriForFile(context, getString(R.string.file_provider_authority), media);
Intent share = new Intent(Intent.ACTION_SEND);
share.putExtra(Intent.EXTRA_STREAM, uri);
share.setType("video/*");
String title = getString(R.string.share_video_title);
Intent chooser = Intent.createChooser(share, title);
if (share.resolveActivity(context.getPackageManager()) != null) {
    startActivity(chooser);
}

共享在gmail（例如）和似乎上可以完美地工作，从而在whatsapp上也可以正常工作。它压缩视频并上传。收件人获取视频，并能够查看缩略图并下载。但是他们无法播放视频。

我终于找到了解决方法

public void shareVideoWhatsApp() {


        Uri uri = Uri.fromFile(v);
        Intent videoshare = new Intent(Intent.ACTION_SEND);
        videoshare.setType("*/*");
        videoshare.setPackage("com.whatsapp");
        videoshare.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        videoshare.putExtra(Intent.EXTRA_STREAM,uri);

        startActivity(videoshare);

    }

您尝试这样做吗？

String path = ""; //should be local path of downloaded video

        ContentValues content = new ContentValues(4);
        content.put(MediaStore.Video.VideoColumns.DATE_ADDED,
                System.currentTimeMillis() / 1000);
        content.put(MediaStore.Video.Media.MIME_TYPE, "video/mp4");
        content.put(MediaStore.Video.Media.DATA, path);

        ContentResolver resolver = getApplicationContext().getContentResolver();
        Uri uri = resolver.insert(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, content);

        Intent sharingIntent = new Intent(Intent.ACTION_SEND);
        sharingIntent.setType("video/*");
        sharingIntent.putExtra(Intent.EXTRA_SUBJECT, "Hey this is the video subject");
        sharingIntent.putExtra(Intent.EXTRA_TEXT, "Hey this is the video text");
        sharingIntent.putExtra(Intent.EXTRA_STREAM,uri);
        startActivity(Intent.createChooser(sharingIntent,"Share Video");
