This link will give detailed information on how to get Google Map Key for Android Application. I don’t need to repeat it. Here I just want to give simplified steps for future reference:

1. Get MD5 Fingerprint of the Certificate

a) SDK Debug Certificate

b) Your Signing Certificate

2. Go to this link to sign up for an Android Maps API key

3. Add the key to your application’s AndroidManifest.xml

android:layout_height="fill_parent"
android:apiKey="[your key]"
/>
