This application has been designed for use with the standard Android music player, but also tested for Walkman Player and a variety of other music players. If your application doesn’t work as expected? Please try to activate/deactivate the headset control in the music player itself since this might be in conflict with this application.
The SmartKey application supports Android 4.0 and above and is designed for Sony Xperia™. It will also support other Android devices although its functionality can be limited.
This application is developed for wired headsets only.
Disclaimer: For coming Android releases there might be changes in how the headset control is handled. This may/may not interfere with this application. This application may be upgraded accordingly, provided it can be handled from the application and not the Android system only. Please enjoy your Sony headset with this headset control application, making living easier.
