STB Emulator is a popular Android App for streaming applications.
One major limitation with STB Emulator when used in GoogleTV Chromecast is Navigation and no scope for "search" function. GoogleTV - remote control has very few keys - With REV-PLAY-FF keys missing , watching a movie or a recorded TV show can be really frustrating. Same with no option to "search" for movie or TV show in a huge library.
After trying all the possibilities I realized that using MAGic Remote App from Informir in mobile phone/Tablet is the ONLY option for navigation when using STB Emulator in GoogleTV.
MAGic remote was free till recently - Now there is a one time charge of appx $5.00 - Still worth it.
MAGic Remote is a clean interface and works well with STB Emulator in any Android device.
