通过我的应用程序在whatsapp上共享视频

Question

我想分享视频，当用户想分享该视频时，我可以在应用程序中下载该链接及其下载的内容，
现在视频未在whatsapp上共享，我现在不怎么做，这是我的代码
我尝试过但是没有用。

 Intent videoshare = new Intent(Intent.ACTION_SEND);
    videoshare.setType("*/*");


    videoshare.putExtra(Intent.EXTRA_STREAM, Uri.parse(Environment.DIRECTORY_DOWNLOADS+"/"+title));

        videoshare.setPackage("com.whatsapp");
        startActivity(Intent.createChooser(videoshare, "Share video")); 

Answer 1

我终于找到了解决方案

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);

    } 

Answer 2

public void shareVideo(String pkgname, String appname) {
  String path = null;
  try {
    path = MediaStore.Images.Media.insertImage(getContentResolver(),
    arrImagePath.get(slidePager.getCurrentItem()), "Title", null);
  } catch (FileNotFoundException e1) {
    e1.printStackTrace();
  }
  Uri uri = Uri.parse(path);
  Intent share = new Intent(Intent.ACTION_SEND);
  share.setPackage(pkgname);
  share.putExtra(Intent.EXTRA_STREAM, uri);
  share.setType("Video/*");
  share.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
  startActivity(Intent.createChooser(share, "Share image File");
}

shareVideo（“ com.whatsapp”，“ Whatsapp”）;
