My android application using gmap, I have check the api and everything is working fine when I test it in my cell phone. But the map is not loading when I uploaded it to Google Play and download it to my phone. Here is my gmap Api
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="@string/google_maps_key" />
So what's going on here? Why my app is different when I upload it to Google Play? enter image description here
