在Android中分享Intent

Question

是否可以使用Android原生共享意图在Twitter上分享视频？

到目前为止，我的代码中有些内容不允许我分享视频。

Intent intent = new Intent(Intent.ACTION_SEND);
StringBuilder sb = new StringBuilder(); 
intent.setType("*/*");
final PackageManager pm = getPackageManager();
final List<ResolveInfo> activityList = pm.queryIntentActivities(intent, 0);
 int len =  activityList.size();
for (int i = 0; i < len; i++) {
final ResolveInfo app = (ResolveInfo) activityList.get(i);
                if (app.activityInfo.packageName.toLowerCase().contains(appName) || 
                        app.activityInfo.name.toLowerCase().contains(appName)) {
                    final ActivityInfo activity=app.activityInfo;
                    final ComponentName name=new ComponentName(activity.applicationInfo.packageName, 
                            activity.name);
                    intent=new Intent(Intent.ACTION_SEND);
                    intent.addCategory(Intent.CATEGORY_LAUNCHER);
                    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
                    intent.setComponent(name);
                    intent.putExtra(Intent.EXTRA_TEXT,      "sample message");
                    intent.putExtra(Intent.EXTRA_STREAM,    Uri.fromFile(file));
                    startActivity(intent);
                    break;
                }
            }
