Dionissm, In general, all as I imagined. Only on my tablet, the remote is always displayed in landscape mode, that is, the screen is not rotated. Well, it's okay.
A couple of comments. I know only one program similar to yours. According to the rules of the forum will not call. There is the remote mode (stop, pause, volume) works whether to file an application or not. The program makes it systematically, however requires root. If we talk about TV applications, the program button is not there, but the arrows on the remote control allow you to select a program as if connected physical keyboard, I feel more comfortable, as if you need to go to 10 programs up and simply pressing the program up takes a long time . It is clear that you can use the touch pad, but the remote is not very convenient. In general, the main advantage of the program, the touch panel is enabled by a minimum. Including to select an application. That is to say that in your program longer have to look at the screen rather than the remote at the TV.
But all this is only my opinion. We correct your application will also be in demand.
And second, that the program fully emulates gamepad for his fellow game (Asphalt 8, for example), but without the presence of physical buttons to play is not very convenient, because in the dynamic games ever Tapan centimeter by and because of this you do not feel, but everything works fully, and the rest is a matter of habit.
