Send preinstalled app activity

You can use the Adjust SDK to record activity from apps that came preinstalled on a user’s device. This enables you to send information from users who didn’t download your app from a campaign.

To enable preinstall measurement, call the enablePreinstallTracking method of your config object.

1
const adjustConfig = new AdjustConfig(
2
   "{YourAppToken}",
3
   AdjustConfig.EnvironmentSandbox,
4
);
5

6
adjustConfig.enablePreinstallTracking();
7

8
Adjust.initSdk(adjustConfig);

Default link token

Configuring a default link token enables you to attribute all preinstalls to a predefined Adjust link. Adjust records all information against this token until the attribution source changes. To set this up:

1. Create a new campaign link in Campaign Lab.

   1
   https://app.adjust.com/{token}

2. Copy this token and assign it to the defaultTracker property of your config object.

   1
   const adjustConfig = new AdjustConfig(
   2
      "{YourAppToken}",
   3
      AdjustConfig.EnvironmentSandbox,
   4
   );
   5
   
   6
   adjustConfig.setDefaultTracker("{TrackerToken}");
   7
   
   8
   Adjust.initSdk(adjustConfig);

3. Build and run your app. If you have logging enabled, you should see a message in your log

   1
   Default tracker: 'abc123'.
