how to use app links to pass parameter to android playstore to be retrieved when app is installed

Question

I'm developing a social android trivia game. When a user challenges to a game a friend, who doesn't have my trivia game installed, i'd like to send him a custom url to download the app from the market containing a parameter of the inviting user id.

when the app is run for the first time, i need to be able to receive the parameter passed to the market, in order to identify the user and show him the game he was challenged to. i couldn't figure out how to do this with app links and didn't find any appropriate example.

any help would be greatly welcomed! Thanks, Ido

To send data to the Android Market, you have to build an uri like this one:

market://details?id=my.package.name&referrer=someDataToTransfer

To get this data back, you should implement an INSTALL_REFERRER Receiver.

<receiver android:name="my.package.MyReceiver"
          android:exported="true">
   <intent-filter>
   <action android:name="com.android.vending.INSTALL_REFERRER"></action>
   </intent-filter>
</receiver>

Here is a short tutorial that will explain you how to fully implement this solution.

And if you want to test it without writting any code, checkout my app: Install Referrer on GitHub or on the Play Store
