Start appium without launching my application


I’m trying to do the following:

Start a appium and not install & open my application, then i can check if the language of my device is EN (if not, switch to EN). Then, i can open my application and begin the tests.

I tried autoLaunch capability, but when i set it to False i get: TypeError: Cannot read property ‘sendAction’ of null

Is there a way to do it?
