Google Maps API Key Not Being Picked Up

#1

Hi, all. I’m trying to build a standalone app using exp build:android. I’ve got the following app.json (trimmed for speed’s sake):

{
“expo”: {

“android”: {
“config”: {
“googleMaps”: {
“apiKey”: “[mystery key here]”
}
}
}
}

I have not published to Play Store yet. I’m still testing with adb install on a Genymotion emulator. When I attempt to hit Google Maps, here’s what I see in adb logcat:

06-22 03:33:46.246 7129 7129 I Google Maps Android API: Google Play services package version: 12685026
06-22 03:33:47.074 7129 7256 E Google Maps Android API: Authorization failure. Please see https://developers.google.com/maps/documentation/android-api/start for how to correctly set up the map.
06-22 03:33:47.075 7129 7256 E Google Maps Android API: In the Google Developer Console (https://console.developers.google.com)
06-22 03:33:47.075 7129 7256 E Google Maps Android API: Ensure that the “Google Maps Android API v2” is enabled.
06-22 03:33:47.075 7129 7256 E Google Maps Android API: Ensure that the following Android Key exists:
06-22 03:33:47.075 7129 7256 E Google Maps Android API: API Key: AIzaSyCPyKmt6in3JwAsogYikNNjor8qgU9stRQ
06-22 03:33:47.075 7129 7256 E Google Maps Android API: Android Application (<cert_fingerprint>;<package_name>): [MYSTERY CERT AND NAME HERE]

That is very much not the API key I put in my app.json file or what I have on Google’s API console. I know app.json is being read, though, because my icon and splash screen shows up when I install and run the APK.

I’m pretty sure the key highlighted above is a default public key getting pulled in from somewhere. Am I doing something dumb, or is there something else going on here?

Hi! Have you followed all the instructions here https://docs.expo.io/versions/latest/sdk/map-view#deploying-google-maps-to-a-standalone-app including exp fetch:android:hashes? Make sure to also rebuild the app as mentioned in step 12.

Yup. I also verified the fingerprint and app name being shown in adb logcat was right. The API is the only thing that’s odd. Here’s something I noticed in the exp build:android logs:

▼configuring builder

It doesn’t look like my entire config setting is getting picked up, but everything else is.

Okay I have zero idea what’s different, but I reloaded a native app on Genymotion, and everything’s working fine now. I did bump the versionCode on the app.json, so maybe that knocked loose something that was cached? Anyway, it’s working now :slight_smile:

Thanks!

Weird, glad it eventually worked for you!
