Memory error for downloaded image even though enough memory is available

TLDR: The error seems to be that the Mixpanel SDK uses Runtime.getRuntime().freeMemory() for checking if enough memory is available. This is wrong as the heap may expand dynamically, the documentation (for Android M) states:

    /**
     * Returns the number of bytes currently available on the heap without expanding the heap. See
     * {@link #totalMemory} for the heap's current size. When these bytes are exhausted, the heap
     * may expand. See {@link #maxMemory} for that limit.
     */

Exception was:

The result is that currently no notifications can be shown because the SDK thinks the images are too large - which they are not.

Those startup parameters specify the initial and maximum heap size. totalMemory and maxMemory correlate with those - hence my comment 😃 Dynamically changing the heap size or setting different values for Xms and Xmx are valid scenarios for this fix. Will keep an eye if someone else is having issues with notifications and will make a release if needed. Thanks @mreichelt !

Sure thing 😃
