usb On The Go - pm3 WITHOUT ROOTING THE SMARTPHONE

did someone tried to connect the pm3 with usb otg?

NOTE: since i don't want to root the phone, we need to use the android libraries to communicate on usb:
read this: http://developer.android.com/guide/topics/connectivity/usb/host.html

The question is: what data format we will receive from the pm3 connected to the smartphone by using the android libraries?
could we directly communicate like the client does, or do we have to develop a driver layer protocol?
I suppose the first one is the answer.

Re: usb On The Go - pm3 WITHOUT ROOTING THE SMARTPHONE

A lot of payment software on the Play Store requires root.
I think there are no workarounds on this, because if a developer intend to sell an app in order to gain money, it would be in his interest to make that app working without root, so he can hope in more customers...
I rooted my galaxy tab 8 only for trying proxdroid...
Just remember that you can reset the famous "counter" with a specific app, so why not root?

Well root is available on 90% (maybe more) Android devices but usually root void your warranty. A rooted phone is more exposed to "external risks" but it is FAR AWAY better than a stock (non-rooted) firmware in terms of performance if you do the appropriate tweaks (anyway if you don't know what you are doing you can make unwanted behaviour and system instability).
