For example, Mixpanel’s SDK queues events and then flushes them only when the app goes to the background. The queue behavior might differ for Device-mode destinations. Since the data is saved immediately, it isn’t lost even if the app is killed or the operating system crashes. When the queue size reaches the maximum size you specify (20 by default), the library flushes the queue and uploads the events in a single batch. When you send an event, the library saves it to disk. This limits the number of network calls made, and helps save battery on the user’s device. The Analytics-Android library queues API calls and uploads them in batches. You may need to upgrade your Analytics-Android version and your device-mode destination versions to be compliant with Google Play policies. Note: From 4.10.1, Segment no longer collects the Android ID to comply with Google’s User Data Policy. Note: If this ID didn’t generate previously (for example, because the app was newly installed or updated from an older version), an empty string shows before the ID generation completes. If you choose to override the default value, make sure the identifier you choose complies with Google’s User Data Policy. Some destinations rely on this field being the Android ID, so be sure to double-check the destination’s vendor documentation. Segment also generates a unique ID by using the DRM API as. This is the ID that should be used for advertising purposes. Make sure the Play Services Ads library is included as a dependency for your application. The Segment SDK also collects the Advertising ID provided by Play Services. To create a new user on the same device, call reset on the Analytics client.

This is used as the anonymousId and stays constant for the user on the device. The very first time an Android app that uses Segment launches, the Segment SDK generates a UUID and saves it on the device’s disk. Naturally the Analytics SDK needs a unique ID for each user. This is especially important for funnel conversion analysis and retention analysis. To do this, the platform must assign and persist some form of identification on the device, so you can analyze user actions effectively. One of the most important parts of any analytics platform is the ability to consistently and accurately identify users. In addition to the documentation here, you can also read the Javadocs for all versions of Analytics-Android on Javadoc.io.
