new UsbStorage()
UsbStorage listens to lock and unlock events and changes the setting which controls automount behavior of USB storage.
UsbStorage listens to lock and unlock events and changes the setting which controls automount behavior of USB storage. Storage operates both on lock/unlock events, as well as the ums.enabled setting which is set in the settings app.
Once storage has been enabled (which requires the phone to be unlocked), we want to keep it enabled, even if the phone is locked afterwards. However, unplugging the USB cable should then require being unlocked before enabling again.
This also needs to work properly if the lockscreen is disabled.
Some further potential wrinkles:
- MTP can be enabled/disabled at will
- UMS can be enabled at will, but requires a USB cable unplug to complete.
