I am trying to make Mixpanel people tracking to work but with no success. I see in the logs, that a create alias event is sent but in the Mixpanel console no user profile is created.
Also this is code from the demo app in which I managed to replicate the issue, I can't share code from original app due to confidentiality reasons.
class MainActivity : AppCompatActivity() {
lateinit var mixpanel: MixpanelAPI
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
mixpanel = MixpanelAPI.getInstance(this, "mytoken")
mixpanel.people.set("open date", Date())
mixpanel.identify(mixpanel.distinctId)
setContentView(R.layout.activity_main)
initCustomer()
postToMixpanel("TEST EVENT")
MPLog.setLevel(MPLog.VERBOSE)
}
fun initCustomer() {
mixpanel.alias("1", mixpanel.distinctId)
val map = listOfNotNull(
"\$name" to "Nikola",
"Gender" to "Male",
"Attraction" to "Girls",
"Account type" to "WTF",
"\$email" to "mail@mail.com"
).toMap()
mixpanel.people.setMap(map)
mixpanel.flush()
}
fun postToMixpanel(eventId: String, additionalProps: Map<String, Any>? = null) {
val props = JSONObject()
additionalProps?.let {
for ((key, value) in it) {
props.put(key, value)
}
}
mixpanel.track(eventId, props)
}
}
These are mixpanel logs from create alias event, I can not see any special property in there such as $name and $email.

Try calling identify() method on the people object. It should create a user in Mixpanel.
mixpanel.people.identify(mixpanel.getDistinctId());
after
mixpanel.alias("1", mixpanel.distinctId)
in your fun initCustomer() method.
Example:
fun initCustomer() {
mixpanel.alias("1", mixpanel.distinctId)
mixpanel.people.identify(mixpanel.getDistinctId());
val map = listOfNotNull(
"\$name" to "Nikola",
"Gender" to "Male",
"Attraction" to "Girls",
"Account type" to "WTF",
"\$email" to "mail@mail.com"
).toMap()
mixpanel.people.setMap(map)
mixpanel.flush()
}
