mixpanel-android: Memory leak

Hi,

After some investigation on my app, I have detected an huge memory leak coming from Mixpanel (see attached pictures). For the moment I have no idea where it comes from but it appear as soon as I call : MixpanelAPI.getInstance(my_context, MIXPANEL_TOKEN);

The android studio allocation tracker confirms that it comes from the Mixpanel package.

Following my investigation :

• If I call the flush method, the leak is stopped when the app is in the bakground.
• If I don’t call the flush method, the leak is still present when the app is in the bakground.
• If I call the getInstance(…) method with the wrong Token, I get no leaks.
• I have tried with version 4.5.1 and the issue is the same (my current version is 4.6.4)
• I have tried to move the Mixpanel initialization in another activity : same issue
• Same issue on multiple android version (lollipop, kitkat …).

Any idea ?
