Answer 2

Please go through this

With the following command you dont generate Fingerprint (MD5 Fingerprint more specifically) for you android device. You generate MD5 Fingerprint against keystore (C:\\Users\\abc_username.android\\debug .keystore in your case) you are using for android development.

C:>keytool -list -alias androiddebugkey -keystore C:\Users\abc_username.android\debug .keystore -storepass android -keypass android

In Android this Fingerprint is useful to get Google Map api key which we can use in MapView.

If you change keystore, you will have to regenerate this fingerprint regarding to new keystore for getting api key from Google for MapView

About keytool

keytool is a key and certificate management utility. It enables users to administer their own public/private key pairs and associated certificates for use in self-authentication (where the user authenticates himself/herself to other users/services) or data integrity and authentication services, using digital signatures. It also allows users to cache the public keys (in the form of certificates) of their communicating peers.

Hope this will help you
