Google Map Android API v2 can't display map in play store application

Question

I am working with the Google Map Android API v2 in an android application.

It works fine with the unsigned apk on a different device. B

Answer 1

This happens because mapApi key is different for signed apk and unsigned apk.

You have to generate SHA1 key using your keystore with which you singned your apk.

Don't worry just follow the steps.

open terminal and fire command

keytool -list -alias -keystore -v

Take SHA1 key from List

Open your google api console and generate new key and give SHA1 key with your packagename

Put the new map api key in your code.
