Answer 1

我终于找到了解决办法是在这里

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”）;
