Confirmed. I had the same problem after upgrading to Tools version 20. I had to Edit the AVD to add an option as follows:
- From Eclipse, Go to AVD Mananger.
- Select the particular AVD and click on Edit
- Go to the Hardware section, click on New.
- Select the Property Name : Keyboard Support
- By default, it is added with a value of 'no'. Just click on the value column and change it to 'yes'.
- Click on Edit AVD again.
This will add a property hw.keyboard=yes in config.ini file for the AVD.
You also have to set hw.mainKeys = yes
