I am using the Facebook app installed on my device for posting data on Facebook. I want to come back to my app after clicking and posting on Facebook, but I found no way to do this. Is there a way?
I am opening the Facebook app on the device through a URL scheme.
If you want to communicate with Facebook in your own app, you will need to use the Facebook API and program it into your app. Check this page out for the official Facebook API and directions on how to integrate it into your app.
Edit: If you are opening the Facebook App through a URL scheme, you will not be able to return to your own app after. Doing so would require you to add some code to the Facebook App itself. I suggest you check out and use the Facebook API.
