I have a keystroke from google for my app.
But there is no way I can download the key directly from the page where google displays it for me.
Which page is that? You shouldn't download a key in order to sign your application.
Or do you mean the debug.keystore
which comes with the installation of the Android bundle? You can use it during development, but you need to create your own key when releasing the App. (Google Play won't accept an apk
signed with the debug keystore)
If you are not releasing yet and you want to use the debug keytore - search your system for 'debug.keystore'. On Windows it can be in:
C:\Users\USERNAME\.android\debug.keystore
The passwords for the keystore and the android alias are android
.
If however you want to create a new key for yourself - you can do that using the provided keytool
as described here.
Finally, if you need an additional key for accessing some Google API (eg. Maps) with your App, then from the online developer console you need to create an additional Android key with the same fingerprint, as the one that you are signing the App with. This additional key is typically included in your manifest after that.
For reference, you can create new keys for your App here: https://console.developers.google.com
