Hi,
The number of plugins to port is getting quite difficult to manage as part of the wiki. Many Publishers are already taking part of this and start handling playmaker actions and bridges themselves. It make sense.
Do you have a plugin on the asset store that you think would be usable for you? I searched for "google play" int he asset store and there are a lot of different solution. have you studied them? It's likely the right path to take: pick a plugin that fits your need and we'll see how we can integrate it within playmaker. If in doubt, let me know and I can also get in touch with a particular publisher to verify feasibility and how we can work together to get things done on that front.
If you are in tight deadline, pm me to arrange something, full credits to members that funds playmaker custom actions developement.
Also, I do encourage you to dive into this. custom actions development is not difficult, as you simply pick snippets form here and there ( within the official actions or on this forum). I never write anything from scratch, the issue is time, as generally such plugins requires heavy testing, we can' really provide something half tested... so this is where it starts to become costly. you can do that you have a project to test it on. I could give you an initial push, with few typicaly actions, or the hard ones at least.
bye,
Jean
