问题
For our android app we have had customers that report the program crashes after updating their system from Lollipop to Marshmallow. The program works fine if they do a clean install on Marshmallow, it only happens when they update.
I am trying to recreate their environment on a emulator. The problem I am encountering is I can not figure out how to install the program on Lollipop in the emulator then upgrade the emulator to Marshmallow so I can run a debugger on the program to see where it actually is failing.
We have no physical devices still on Lollipop that are eligible to be updated to Marshmallow.
What is the process for testing upgrading your OS on android without a physical device to update?
