In order to develop an application that uses the Google Maps, you should obtain first a Maps API key registered via the MD5 fingerprint of the debug certificate. To find the MD5 fingerprint of your debug certificate you should use the keytool to generate it.
When using the keytool you may encounter following error:
The Keytool as well as jli.dll files are part of Java SDK /bin directory, and when you generate the MD5 code, both Keytool and jli.dll files should be in the same directory, if they are not in the same directory, then the above error is thrown.
The simplest way to generate the MD5 fingerprint is to:
1. Copy both keytool and jli.dll into debug keystore location:
- Windows Vista:
- Windows XP:
C:\Documents and Settings\<user>\.android\debug.keystore
- OS X and Linux:
2. Navigate with the command prompt to debug keystore location and run the following command to:
a) generate a Debug certificate:
keytool -list -alias androiddebugkey -keystore debug.keystore -storepass android -keypass android
b) generate a Release certificate:
keytool -list -keystore debug.keystore
3. Copy the generated MD5 fingerprint and navigate to http://code.google.com/android/maps-api-signup.html to get the Map key.
