In my app, I used FCM and Google Maps. I have 2 API Keys. Android does not allow me to use them together.
How can I use one API Key for the both of them?
For Maps API, you need to add the following line in your manifest:
<meta-data android:name="com.google.android.geo.API_KEY" android:value="YOUR_API_KEY"/>
And for FCM the key, it can be seen in your Firebase Console in the Cloud Messaging tab.
