Ionic v2 Google Maps API Android Build Error: cann

问题:

I'm trying to implement the Google Maps API using the Ionic docs as seen here.

I'm using the code samples exactly as supplied, but I'm getting the following error:

BUILD FAILED

Total time: 2.748 secs

Error: /path/to/platforms/android/gradlew: Command failed with exit code 1 Error output:

Has anyone seen/resolved this issue?

回答1:

I was able to resolve the issue. While a lot of the suggestions I found revolved around installing missing repositories (you need Android Support Repository, Library, Play Services and Google Repository), I had all that in place. What was missing was that incorrect versioning is specified in project.properties when I used this command to add the plugin:

ionic plugin add cordova-plugin-googlemaps --variable API_KEY_FOR_ANDROID="YOUR_ANDROID_API_KEY_IS_HERE" --variable API_KEY_FOR_IOS="YOUR_IOS_API_KEY_IS_HERE"

In project.properties, I changed this:

cordova.system.library.4=com.google.android.gms:play-services-maps:9.8.0
cordova.system.library.5=com.google.android.gms:play-services-location:9.8.0

To this:

cordova.system.library.4=com.google.android.gms:play-services-maps:+
cordova.system.library.5=com.google.android.gms:play-services-location:+

That resolved the build error.
