Map Not display in Android

Solution

The MD5 Fingerprint of Your Signing Certificate Should Be provided in your Main.xml

To register for a Maps API Key, you need to provide an MD5 fingerprint of the certificate that you will use to sign your application. Before you visit the registration page, use Keytool to generate the fingerprint of the appropriate certificate. 

First, if you are testing the application on the Android emulator, locate the SDK debug certificate located in the default folder of "C:\Documents and Settings\\Local Settings\Application Data\.android". The filename of the debug keystore is debug.keystore. For deploying to a real Android device, substitute the debug.keystore file with your own keystore file.

Using the debug keystore, you need to extract its MD5 fingerprint using the Keytool.exe application included with your JDK installation. This fingerprint is needed to apply for the free Google Maps key. You can usually find the Keytool.exe from the "C:\Program Files\Java\\bin" folder.

Issue the following command to extract the MD5 fingerprint.

C:\Program Files\Java\jdk1.6.0_14\bin>keytool -list -alias androiddebugkey -keystore "c:\Documents and Settings\check\.android\debug.keystore" -storepass android -keypass android
