I need to use mapview control in android and I can\'t seem to understand how to run keytool.
Is it installed with eclipse? I can\'t seem to find a download link
keytool is part of the standard java distribution.
In a windows 64-bit machine, you would normally find the jdk at
C:\Program Files\Java\jdk1.8.0_121\bin
It is used for managing keys and certificates you can sign things with, in your case, probably a jar file.
If you provide more details of what you need to do, we could probably give you a more specific answer.
