How to programatically initialize Follow-a-WeChat-official-account screen in WeChat, from my Android app
<p>I am building an Android app with some 3D experience. At the end of the experience, user will be shown a button to click on to "Follow us on WeChat". When user clicks on it, ideally, I'd like to invoke WeChat app (which I know user will 100% have it installed on his device) and to open the screen to follow my official account.</p>

<p>I've been looking at WeChat Android SDK as well as googling around, but haven't found any straightforward solution that works. There used to be a URL-based instruction (wx:// or weixin://, something like that) but that appears not to work anymore: <a href="https://stackoverflow.com/questions/23780506/open-wechat-official-account-via-link-on-external-page">Open Wechat official account via link on external page</a></p>

<p>I've read that WeChat has disabled above option because of mass abuse, and the only way is to initialise "Scan QR code to follow" inside WeChat. Now, I can do this from an HTML5 page that runs inside WeChat, but I'd need to somehow do this from my own Android app.</p>

<p>Basically, I'd have a QR code on my app's screen, and ideally, would somehow on user click / long press, launch WeChat app and pass QR code image to it. Or any other workaround, if this is not possible?</p>

<p>Thanks in advance!</p>
