Quirks
Android
For compatibility with react-native-maps v0.20.1 library versions were locked in root build.gradle file:
ext {
compileSdkVersion = 23
targetSdkVersion = 23
buildToolsVersion = "23.0.3"
supportLibVersion = "23+"
googlePlayServicesVersion = "11+"
androidMapsUtilsVersion = "0.5"
}
More info https://github.com/react-community/react-native-maps/blob/v0.20.1/docs/installation.md
As version 0.20.1 of react-native-maps there is another issue,
which was resolved by updating following lines in app/build.gradle:
compile(project(':react-native-maps')) {
exclude group: 'com.google.android.gms', module: 'play-services-base'
exclude group: 'com.google.android.gms', module: 'play-services-maps'
}
compile "com.google.android.gms:play-services-base:11+"
compile 'com.google.android.gms:play-services-location:11+'
compile 'com.google.android.gms:play-services-maps:11+'
React-native-maps version 0.21 is not supported yet.
Troubleshoot
Android
Check adb logcat for errors. For example wrong API key:
E/Google Maps Android API(31792): Authorization failure. Please see https://developers.google.com/maps/documentation/android-api/start for how to correctly set up the map.
E/Google Maps Android API(31792): In the Google Developer Console (https://console.developers.google.com)
E/Google Maps Android API(31792): Ensure that the "Google Maps Android API v2" is enabled.
E/Google Maps Android API(31792): Ensure that the following Android Key exists:
E/Google Maps Android API(31792): API Key: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
E/Google Maps Android API(31792): Android Application (<cert_fingerprint>;<package_name>): 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00;com.rnbgexample
