Do not close app after test

Hello! I have a test which opens proxy app and then configures all settings. After that I need to run another test which requires proxy settings to be set in previous app. But after calling driver.quit() proxy app closes and just does not work. I need second driver and capabilities in order to run next test. I know that it is impossible to handle 2 sessions on one device. So how can I leave proxy app opened? Maybe somehow with driver.start_activity() ??

Alright driver.start_activity() did the trick. Now it is working
