Obtaining Android Public Map API Key

I have been trying to obtain a public map api key for my Android app. However the public key that I receive from 开发者_如何学PythonGoogle does not work.

I have been using the following steps:

---

Obtaining Release Public Map API Key

1.Obtain Private Key:

• Use Export of Eclipse to sign release application and create new keystore

2.Obtain MD5 certificate:

• using alias and keystore set up

• use keytool in Java directory: keytool -list -alias poly_alias -keystore

• copy MD5 certificate

3.Obtain API Map Key:

• Visit http://code.google.com/android/maps-api-signup.html and enter MD5 certificate
• copy key

4.Use New Map API Key:

• insert new map key for string in strings.xml for string mapApiKey

Does anyone have any suggestions on what I am doing wrong?

You were sketchy on the last step, so you may want to look at the final two steps on this page:

http://code.google.com/android/add-ons/google-apis/mapkey.html#finalsteps.

If it still doesn't work, you may want to explain what is happening, and change the values, but you may want to show an example of one of your layout files and the android manifest, to see if you may have made a typo or something.

You are following instructions for using the release signing key. Make sure you are building your APK in release mode. Normally, you build in debug mode and would use a Maps API key based on the debug signing key.
