We promote our app (iOS & Android) a lot to get new user installs via Facebook.
Using the Facebook SDK 3+ (iOS & Android), you can measure app installs (https://developers.facebook.com/docs/tutorials/mobile-app-ads/). Titanium Facebook module implements the SDK 3.0.0 so it is possible to use this.
We observe, in our Facebook app dashboard, that iOS new installs are properly reported, but that is not ok on Android. Is there anybody here that observed the same issue? This Jira seems to confirm it : https://jira.appcelerator.org/browse/TIMODOPEN-246?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
We fixed the Facebook module for Android. But impossible to test it; the app should be published on Google Play to test the implementation: http://stackoverflow.com/questions/13131899/is-it-possible-to-use-the-facebook-mobile-sdks-for-only-mobile-app-install-ads.
Here is the fix we made: https://github.com/shopmium/titanium_modules/commit/9865df7bbc36739893dfdb33bfd57cc4f37eee51 Is it ok for you ?
