Android : create Google+ Poll

Few days ago Google announces new feacher a poll in G+. I was wondering how to create poll from application for user.

Look at Sample Pool

For example now when i want to share something on G+ i use:

// Launch the Google+ share dialog with attribution to your app.
Intent shareIntent = new PlusShare.Builder(activity)
        .setType("text/plain")
        .setText("Mobiliada")
        .setContentUrl(
                Uri.parse("https://play.google.com/store/apps/details?id=com.dexode.question&referrer=utm_source%3Dshare_gplus2%26utm_medium%3Dreferral"))
        .setContentDeepLinkId(
                "https://play.google.com/store/apps/details?id=com.dexode.question&referrer=utm_source%3Dshare_gplus2%26utm_medium%3Dreferral")
        .getIntent();

    activity.startActivityForResult(shareIntent, REQUEST_GOOGLE_PLUS);

So how to create poll rom my app?
