MediaVolCtl

It mutes the media volume. Even if you touch the VOL key by mistake It will not sounds music from speaker.
When you plug headphones (including Bluetooth), unmute automatically, return to mute when unpluged.
Manual switching of the mute state is also possible by tapping the widget.
If there is an image file with the following name under the main storage, replace the icon image.( mediavolctl_on.png / mediavolctl_off.png )


Placing "mediavolctl.log" in the main storage outputs the debug log.

The following shell command can switch the mute state.
Mute am broadcast -a com.jp.ssipa.mediavolctl.ACTION_MUTE
Un-mute am broadcast -a com.jp.ssipa.mediavolctl.ACTION_MUTE_OFF
