Google map can be displayed on emulator but not in Android Device

I want to get .apk file for final version, but when i install the program on the phone, the program does not shows the map but when i run the program in eclipse, the program runs correctly. I think, maybe the program doesn't have map libray. What is the problem? What should i do?

It's because you are deploying using the Google Maps Api key for debug, not for release.

You should read https://developers.google.com/maps/documentation/android/mapkey.

Hope it helps, and if you need more helps let me know.

Steps to generate apiKey for release:
1. Build Keystore - from eclipse > right click on project and then android tools > Export Signed Application Package 2. Open cmd and write 

c:\Program Files (x86)\Java\jre7\bin > keytool -v -list -alias <your alias> -keystore <path to keystore>

where < your alias > is one used when generating the keystore
< path to keystore > to path where you have placed the keystore
This command can be different for you.

You will get the MD5 code needed for generating the api key.

Hope this helps.

  • I obtain apiKey and i write my apiKey to my prgram but finla version not shows map. Do may i fill fields with incorrect information? – Pariya Daghoghi Nov 01 '12 at 15:37
  • @PariyaDaghoghi: Just read the freaking instructions on the given page. You might have 2 API keys: one related to your debug signing certificate, the other related to your "export" signing certificate. – OcuS Nov 01 '12 at 15:39
  • Did you got apiKey for android debug.keystore and for jre? I had the same problems when building the apk and forget to change apiKey from debug to release. If you didn't do both, you will have to build a keystore from eclipse (right click on project and then android tools > Export Signed Application Package) and then execute in cmd something similar to this command : c:\Program Files (x86)\Java\jre7\bin > keytool -v -list -alias -keystore where yourAlias is one used when exporting from eclipse – Adrian C.

  • Thanks for help but i don't understand what do you mean about your alias!! how i find this?? what is between bin and keytool? Thanks – Pariya Daghoghi Nov 01 '12 at 16:00
  • You should check [this](http://techdroid.kbeanie.com/2010/02/sign-your-android-applications-for.html) tutorial for creating keystore (with alias) in eclipse. If you want, you can read [Signing Your Applications](http://developer.android.com/tools/publishing/app-signing.html) – Adrian C. Nov 01 '12 at 16:17

  • When i write this in cmd, cmd has errors. If i write C:\Program Files (x86)\Java\jre7\bin in front C:\Users\Fahimeh> . but cmd writes C:\Programs is not recognized as an internal or external command. WHy? WHat is the problem? – Pariya Daghoghi Nov 01 '12 at 16:57
  • You need to navigate using commands to c:\Program Files (x86)\Java\jre7\bin and there you will write your command. To Navigate backward you will write cd.. and forward eg.: cd Program Files (x86) – Adrian C. Nov 01 '12 at 17:01
  • Thank you. I write this and i'm sure directory address and alias is true but cmd write The syntax of the command is incorrect. – Pariya Daghoghi Nov 01 '12 at 17:16
  • keytool -v -list -alias pariya -keystore e:\name.keystore. I tested this command right now on Windows 7 and works. – Adrian C. Nov 01 '12 at 17:20

  • check if you typed correct. Before keytool -list you probably have an illegal option caused by a misspelling – Adrian C. Nov 01 '12 at 20:37
