I have a TV that runs android 2.2. It can take a USB mouse and keyboard, and I'm running the dolphin web browser on an auto-refreshed page for digital signage. Only thing is, I can't get it to zoom in or out - there is no touch (so multitouch doesn't work), and there are no +/- buttons as tehre are on some stock browsers. The stock browser doesn't work on the site in questions, and firefox won't load onto the device (it has a MIPS processor, so any app using the native SDK won't work). Any ideas?
Purchase a mouse which supports multitouch gestures (using which you zoom in or out). e.g. PadKite
If you don't want to purchase anything, just go to Dolphin's
Lab and turn ON
pinch-Zoom Button. Then, you'll find +/- clickable buttons to zoom in or out.
