Just a note in case anyone is interested, any Android app can be presented on a projector or other large screen using a ChromeCast device.
I’ve been giving presentations for the past couple of years at multiple locations using only android devices (my android phone and tablet) and a ChromeCast dongle.
Recent os versions starting with KitKat have a “cast screen” option on the second notification pulldown and after connecting with the chromecast device, everything that happens on the android device is displayed on the device that the chromecast is connected to.
There is a learning curve and some “gotchas,” notably connecting to unfamiliar wifi systems, but, I eventually ended up using my phone as a hotspot rather than jumping through hoops to connect to wifi at the presentation locations. If anyone is interested, I will be glad to share what I have learned.
In a couple of cases, I was also able to use an HDMI to VGA adapter connected to a ChromeCast dongle to present on older projectors that had VGA but not HDMI… tip, use an HDMI to VGA adapter that requires a power supply to function.
It’s pretty amazing that you can do a high quality demo using devices that will all fit in a single pocket. It’s also surprising that you can do this using ChromeCast on a handheld device but not on a laptop
Hope that this information is helpful,
