There are two keys that you can do with this, one the debug and the second for the release key. Basically is the same thing just that the debug key is already made for us and it is used when you run the app from your IDE ..
So to generate the SH-1 key you can do the following:
Open terminal and write down the following commands:
keytool -list -v -keystore /Users/your_mac_user_name/.android/debug.keystore -alias androiddebugkey
keytool -list -v -keystore path_to_your_key -alias key_alias
The output for the debug key would be something like this:
Alias name: androiddebugkey Creation date: Jun 26, 2013 Entry type: PrivateKeyEntry Certificate chain length: 1 Certificate: Owner: CN=Android Debug, O=Android, C=US Issuer: CN=Android Debug, O=Android, C=US Serial number: 51cacdf4 Valid from: Wed Jun 26 14:18:12 EEST 2013 until: Thu Jun 26 14:18:12 EEST 2014 Certificate fingerprints: MD5: 1A:2B:C9:33:77:10:FA:B1:1A:C1:63:F1:49:83:71:E7 SHA1: AD:2A:82:A6:11:F5:31:13:E6:7B:3E:75:EB:CF:68:78:9E:3C:44:19 -> YOU NEED THIS CODE FOR GOOGLE MAPS V 2 Signature algorithm name: SHA1withRSA Version: 3
This should be all 🙂
