I have successfully implemented the Facebook SDK and AppEvents to report installation of my Android app. I have verified that it registers the last install data in the dashboard, and I see thousands of fb_mobile_activate_app events in my App Events tab on Facebook.
I have been running a paid campaign on the app, however, even after over 24 hours since adding the SDK, I am getting reports of 0 installs. Since I am basing my budget on how the ads perform, it seems odd to not have any data.
Is there something I am missing here?
Be sure you have your goal point to a Facebook app, and never have to paste in your Google Play URL.
If your mobile app campaigns previously used a Google Play or iTunes link, you'll need to recreate your campaigns to utilize the install tracking via the Facebook Mobile SDKs.
