Title: Hardware Numeric Keypad for Android
Post by: doublethink on Sat, 01 February 2014, 13:01:00
I am wondering if there is anyone out there who has had success with a USB OTG cable and a wired numpad in Android or even iOS.

It is for work and data entry into a google spreadsheet to sync back to my workstation.  I can lug a laptop across the building, or hand write them.  This sucks however.

All i need is the numbers and enter key.  I have played with 12 different onscreen keyboards, and If I use a tablet instead of a phone, I can get some that show a kind of retarded looking numpad by default.

But I would prefer either a bluetooth or hardwired solution on either my phone, or a nexus tablet.

I found this, but I don't speak japanese:

Looks windows only.

Microsoft made one at one point, but its discontinued and also claimed windows only.

Thanks for any input, ideas, anything.

Ok, in case anyone ever wants to try it, a USB OTG adapter and Adesso AKP-220B does work fine with Android 4.0+  You have to turn on numlock each time, but thats no big deal.

There is a bug in Google Drive Spreadsheets with the enter key creating a new line instead of going to the next field, but it is application level because it does the same bug even with a full keyboard attached.  (full 104 key cherry keyboards work too :) )

I took the chance and it worked, so hooray.

good, I have done the same. Most basic devices (mouses, keyboards) will work.
