Hi,
We can have the app running in background and do all the voice recording and pushing the same to the server. But the app needs to have those permission to access calls/ data etc, If that is been removed, we won't be able to do the same.
Is it okay, if the app is been shown in the app list or you want this to be hide (as a plugin). We have done apps which runs in background.
Thanks,
Murugesan
