My app is now in beta and my users are complaining Android sharing is broken with both Facebook and Twitter.
Unfortunately, they are correct. Corona SDK’s implementation of Android sharing forces developers to choose from one of two unpalatable options: share the headline/text (which incorrectly removes Facebook as a sharing option) or don’t share the headline/text (which vexes our users because they have to retype it). Other Android apps like Feedly work properly when the headline/text is shared.
In addition, Twitter sharing is broken because it’s listed twice as “Twitter” in Corona-built apps instead of separately as “Direct Message” and “Tweet.” This works properly on other Android apps.
I’ve posted some more details in this long-running post on the social media forum here:
Hoping that Corona staff can fix this soon! At least it should be a simple fix.
