Question: This question was asked here [Android App base 64 public key](https://stackoverflow.com/questions/12094455/android-app-base-64-public-key) two years ago, but the interface to the Google Developer Console has changed since then. Some documentation refers to <http://market.android.com/publish/editProfile> and everything else that the documentation states is there can be found instead by going to the developer console and then to Settings and then Account details. Not so the key. I have also seen documentation that says the key can be found on the "Services & APIs page in the Developer Console" - Under settings, there is an API section but this is for interfacing to the developer console and you have to "create a project" to gain access. I don't think this is what I need either. There is no services section.

Answer: 
In the [developer console](https://play.google.com/apps/publish), select your app > Services & APIs > "YOUR LICENSE KEY FOR THIS APPLICATION Base64-encoded RSA public key to include in your binary".
In the Google Play Developer Console, select your app and navigate to the following path.

```
YOUR_APP -> Development tools -> Services & APIs

```

Then under the top heading **"Licensing & in-app billing"** you can find your license key for your application.
