Android使用Intent在twitter墙上共享图像和文本

Question

我使用以下代码在twitter墙上分享图片和文字。请帮助我为什么以下代码在我的应用程序中不起作用？启动器活动打开但它只显示文本而不显示图像。并且只分享文本而不是图像和文本。

        Intent share = new Intent(Intent.ACTION_SEND);
        share.setType("image/*");
        final PackageManager pm = mainActivity.getPackageManager();
        @SuppressWarnings("rawtypes")
        final List activityList = pm.queryIntentActivities(share, 0);
        int len = activityList.size();
        for (int i = 0; i < len; i++)
        {
            final ResolveInfo app = (ResolveInfo) activityList.get(i);
            Log.print("Packages", app.activityInfo.name);

            if (app.activityInfo.packageName.startsWith("com.twitter.android"))
            {
                Log.print(":::: Twitter Share Name Activity ::: " + (app.activityInfo.name).toString());

                try
                {
                    final ActivityInfo activity = app.activityInfo;
                    final ComponentName name = new ComponentName(activity.applicationInfo.packageName, activity.name);                          
                    share.addCategory(Intent.CATEGORY_LAUNCHER);
                    share.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
                    share.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                    share.setComponent(name);
                    share.putExtra(Intent.EXTRA_TEXT, Pref.getValue(mainActivity, Labels.TITLE, ""));
                    share.putExtra(Intent.EXTRA_STREAM, new URI(new URL(imgUrl).toString()));
                    startActivity(share);
                }
                catch (Exception e)
                {
                    e.printStackTrace();
                    Log.error(":::: Twitter image path Exception::::", e.toString());
                }

                break;
            }
        }
