android - Google Play Services - Client Version vs Package Version -


i have migrated existing android app android studio / gradle. having problems map, working.

i have cloned android-maps-utils library google , added project. have added dependency android-map-utils gradle.build file.

when load screen contains map, following sequence logcat:

i/google maps android api﹕ google play services client version: 5089000

i/google maps android api﹕ google play services package version: 5089036

i/google maps android api﹕ failed contact google servers. attempt made when connectivity established.

e/google maps android api﹕ failed load map. error contacting google servers. authentication issue (but due network errors).

i going go new maps api key, curious if thinks google play services client version / package version difference causing problem, , how fix it?

the package version shown newer client version, in case not version compatibility issue.

given have api key, causes in case either:

  1. you haven't registered sha-1 fingerprint of signed app in list of authorised apps accessing api key in google apis console (you need debug-signed app)

or

  1. you haven't signed app.

or

  1. permissions missing in manifest:
     <uses-permission android:name="android.permission.internet"/>     <uses-permission android:name="android.permission.access_network_state"/>     <uses-permission android:name="android.permission.write_external_storage"/>     <!-- following 2 permissions not required use      google maps android api v2, recommended. required if access user's current location, either programmatically, or enabling location layer.-->     <uses-permission android:name="android.permission.access_coarse_location"/>     <uses-permission android:name="android.permission.access_fine_location"/>

see app signing / registration description in getting started section maps api: https://developers.google.com/maps/documentation/android/start#get_an_android_certificate_and_the_google_maps_api_key

also, try adding following code before loading map more details on access failure:

string googleerror = null; switch (mapsinitializer.initialize(ctx)) { // or googleplayservicesutil.isgoogleplayservicesavailable(ctx)     case connectionresult.service_missing: googleerror = "failed connect google mapping service: service missing"; break;     case connectionresult.service_version_update_required: googleerror = "failed connect google mapping service: google play services out of date. service version update required"; break;     case connectionresult.service_disabled: googleerror = "failed connect google mapping service: service disabled. possibly app missing api key or not signed app permitted use api key."; break;     case connectionresult.service_invalid: googleerror = "failed connect google mapping service: service invalid. possibly app missing api key or not signed app permitted use api key."; break;     case connectionresult.date_invalid: googleerror = "failed connect google mapping service: date invalid"; break; } if (googleerror != null)     log.d("myapp", googleerror);
