Troubleshooting

Android: "was compiled with an incompatible version of Kotlin"​

The app builds with a Kotlin version older than 2.3.0. See Android Setup.

Android: the map crashes with NoClassDefFoundError​

The missing class is org/apache/http/ProtocolVersion. Devices with an old version of Google Play services draw the map with the legacy renderer, which needs the Apache HTTP library. Apps that target Android 9 or newer only get it when they declare it in the <application> element of AndroidManifest.xml:

<uses-library
  android:name="org.apache.http.legacy"
  android:required="false" />

iOS: pod install fails with "cannot load such file" for svgkit_patch​

The Podfile still contains the svgkit patch from 1.x. Remove it, see Upgrading from 1.x.

iOS: the app terminates when the first map is created​

The Maps SDK has no valid key, either because GMSServices.provideAPIKey was not called before the map was created or because the app contains a second copy of the SDK. See Configure the API key and Native Dependencies.

iOS: import RNGoogleMapsPlus fails in the app​

The module has no public Swift API, its headers belong to the Nitro bridge. Import GoogleMaps directly for GMSServices.
