Volume Changeover

This application changes ON and OFF of the various volume of Android, and is completed.
If it calls from launchers, such as SwipePad, when an earphone falls out and the surroundings have heard sound, it can muffle in an instant and it is not necessary to feel shameful (?).
Please start a Volume Changeover setting application first and choose the item for a volume change.
phone ring, notifications, alarms, music playback, system sounds, and phone calls can be chosen.

ON and OFF whenever only the volume selected here starts a Volume Changeover main part application is changed.
The state where at least one has some whose volume is not 0 in all the selected volume is judged as a "volume ON" state.
(Only when all the selected volume is 0, it is recognized as "volume OFF".)

If a Volume Changeover main part application is started in the state of "volume ON", the present volume value of a volume change target predicate eye will be saved, and it will set up and carry out mute to 0 for all after that.
If a Volume Changeover main part application is started in the state of "volume OFF", it will return to the volume value saved last time, and will cancel ミュート.
(When a preservation value does not exist last time, the item is set up as the volume 0.)

Once setting up, this rule is followed also when the item for a volume change is changed.
Please set up the state of "volume ON" which does not have a function in which this application adjusts volume using a setup of OS, or other applications.
