Im looking to build a time/productivity app. Does fuse have an api exposing some of the core system apis of the phone? For example would I be able to set the phone to silent mode? In java it would be:

AudioManager am = (AudioManager)getSystemService(Context.AUDIO\_SERVICE);  
am.setRingerMode(AudioManager.RINGER\_MODE\_SILENT);

But I would loathe to have to write my own duplicate custom code for andriod and ios for every system level call I would have to do.  
Also, are there apis for exposing other settings like turning off notifications on the phone, dim screen etc etc? I could not readily tell if fuse has this capability exposed. Thanks

Hey Jared.

I think at this moment there is no functionality in Fuse to control device audio. You can write your own code with [Foreign](https://docs.fusetools.com/native-interop/foreign-code.html) code feature.

Hope this helps.
