I'm not a developer nor a programmer but I attempted to get my feet wet anyway with Tasker to try and make a one-press method to kill the two conflicting apps. But no matter what I do, I can't simulate the act of going inside Settings > Apps > Running tab > Litchi > Stop and do the same with DJI Go.
Is there a method to automate this without rooting my phone?
