Should be empty or a custom suffix for the AVD name.<br/>
e.g. "<code>mySuffix</code>" or "<code>withPdf</code>"
<p>
If this field is left blank, no custom suffix will be added to the AVD name that
this plugin generates when automatically creating an emulator.<br/>
If a value is set, a suffix will be added to the AVD name, with any invalid characters
replaced by a hyphen (as AVD names may only contain [a-z A-Z 0-9 . _ -]).

<p>
This allows you to run multiple emulators with the same configuration in parallel on the
same build machine.<br/>
Normally, if you create two jobs with the same emulator configuration, only one of those
jobs will run at a time &mdash; as the other job is using the emulator.  But by setting a
custom suffix one on or both jobs, the emulator names will differ for the two jobs, and
Jenkins will consider them as two completely different emulators, allowing them to run in
parallel.
</p>
Note that this will cause more disk space to be used, as a new emulator will be created
on disk for each unique suffix used.
