How to Upload Android application with Google Maps API v2 inside to Play store?


I got problem that when I ran my application uses Google Map API v2 from eclipse there is no problem, It worked well. But when I uploaded the apk to the Play store and tried installing from Play store the result is the maps is blank. On this article I want to share the solution. The figure just for sample.

The main problem is “I used wrong SHA1 for api key Google Map v2“. I used SHA1 from debug.keystore when I created the api key in the google code console. The right way if you want your application show the maps is you should use SHA1 from release keystore for creating api key, like when you signed your apk for uploading to the Playstore.

Suppose, before you have created the keystore for signing, so we just use the cmd (command prompt) to print the SHA1. The syntax like this

C:\Program Files\Java\jdk1.x.x\bin>keytool -list -v -keystore G:\key.keystorealias author

For example

C:\Program Files\Java\jdk1.6.0_03\bin>keytool -list -v -keystore G:\key.keystore
 -alias yusufmufti

Enter keystore password:
Alias name: yusufmufti

The result like this

Creation date: 01-Mar-2014
Entry type: PrivateKeyEntry
Certificate chain length: 1
Owner: CN=xxxxx
Issuer: CN=xxxxxx

Serial number: 53114ee9

Certificate fingerprints:
         MD5:  96:E5:E6:AC:40:39:FB:24:CE:29:B2:09:B3:95:77:64
         SHA1: 9E:2F:7E:2A:66:94:E4:xxxxxxxxxxxxxxxxxxxxx:94:29:D4:8E (this is your SHA1 for create API key)
         Signature algorithm name: SHA1withRSA
         Version: 3



The result from Playstore the map show.
