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. But when I have signed the apk and uploaded my application to the Play Store the downloaded application displays a white screen instead of the map.

Answer 1

What type of keystore you are using? there are two keys. Debug and release key. If you use debug key and uploaded in android market, map will look blank. Use release key when you signed your apk.

Release key procedure

Step 1:

Say for example your apk name is A and you are signing and creating a keystore for A.apk ie A.keystore will be created in some drive location.Let's consider it in E drive.

step 2:

Now locate to jdk in C drive(Considering for windows and assigning C drive)

C:Program FilesJavajdk1.7.0in>keytool -list -v -keystore E:A.keystore -alias A

So it will create SHA-1 finger print.
