"What does it mean "Unfortunately, Launcher has stopped working?""に関する回答I'm guessing you are talking about launchers on android phones. If so, the launcher usually is considered to be the home screens and app drawer. To resolve the error, goto settings -> Apps -> All Apps -> Scroll down to Launcher -> click Launcher -> Click clear cache -> Restart phone. Alternatively, you can download another launcher from Google Play. Just search Launchers in Google Play.
