If you are working with Android development, you know that you will need a debug MD5 key in order to request a Google Maps API Key.
Most tutorials say to go to C:\users\username\.Android\ and type:
keytool -list -alias androiddebugkey -keystore debug.keystore -storepass android -keypass android
Unfortunately, as of Java 7, the keytool format has changed a bit. In order to see the md5 hash that is required for Google Maps API, you must add a -v flag. The entire command now looks something like this:
keytool -v -list -alias androiddebugkey -keystore debug.keystore -storepass android -keypass android
The new keytool will give you MD5, SHA1, and SHA256 all at once. Enjoy the bonus hashes and your Google working Google Maps API key.
