Remote control widget I am looking to develop a remote control widget on the Android platform which is similar in concept to the JustABlip remote control widget on iOS. So wanted to know whether the android architecture can support such kind of widget development.

Questions like that are off-topic, man. However, there is already an app like it.

ONLY ONE CAN REMAIN

Ahem,
Try the Smart Remote app. Now, I know it's by Samsung (So you are choosing to install crapware) but it Has all sorts of features, including having the remote-get this!- in the notification tray. Try it out some time.

Disclaimer- An android phone may need an IR blaster, or the target device to control allow control over the internet. Like a sky+HD box.
