I would like to have the Tablet showing the apps that i installed inside Pepper robot when it turned on. Following the link, i couldn't get any prompt when i connected Pepper via Choregraphe and start application "j-tablet-browser". The robot is running NaoQi version 2.5.10.7
You could try this application that should do just that (I haven't tested it myself).
For more details, you can also look at the documentation on making applications that use the tablet.
(Normally you don't need to do anything with j-tablet-browser, unlike what the comment you linked said)
