Android Tutorial Google Maps

Installation instructions:

- Register your app in Google developer console: https://console.developers.google.com
You need to enable Google Maps Android API.
Then click on Credentials -> Create Credentials -> API Key -> Android Key.
You should get a key that looks like: AIzaSyCmFHamGE0O0BvxxxxxxxxXbTCSrjFVg-Q

- Copy the attached library and put it in the additional libraries folder. Add a reference to the GoogleMaps library.

- Add this to the manifest editor (replace the value with your key):

CreateResourceFromFile(Macro, FirebaseAnalytics.GooglePlayBase)

AddApplicationText(
<meta-data
  android:name="com.google.android.geo.API_KEY"
  android:value="xxxxxxxxxxxxxx"/>
)

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

Don't add #AdditionalRes or #ExcludeClasses.

- Set minSdkVersion to 14 (Android 4).

- Add a MapFragment with the visual designer. It will appear under the CustomView menu. If you don't see it then make sure that the GoogleMaps library is selected.
You can change the properties from the designer.
Set the anchors to BOTH so the map will fill the activity:

Implement the Ready event to get a reference to the GoogleMap object.
Complete code:

Sub Process_Globals
   Private rp As RuntimePermissions
End Sub

Sub Globals
   Private gmap As GoogleMap
   Private MapFragment1 As MapFragment
End Sub

Sub Activity_Create(FirstTime As Boolean)
   Activity.LoadLayout("1")
   Wait For MapFragment1_Ready
   gmap = MapFragment1.GetMap
   rp.CheckAndRequest(rp.PERMISSION_ACCESS_FINE_LOCATION)
   Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
   If Result Then
       gmap.MyLocationEnabled = True
   Else
       Log("No permission!")
   End If
End Sub

Notes


Updates

- v2.50 - Required dependencies were added to the library.
My Location Enabled property was removed from the designer as it needs to be set after the permission is granted.
- v2.02 EXTERNAL_STORAGE permission removed. It is no longer required.
GetOpenSourceLicenseInfo returns an empty string.
Fixes an issue with the ready event being lost if the activity is paused before the map is ready.

Note that you will need to update the package name and api key in the attached example.

Please create a NEW Thread in the QUESTIONS forum posting the relevant code or better a project which shows the problem.

Thank you. I will do so.

I have installed B4A 8.00. The default GoogleMaps library (v1.01) is outdated. The new one is (v2.00).
I suggest to replace the library in next update to avoid error.

I suggest to replace the library in next update to avoid error.

Google Maps is an additional library which is NOT installed together with B4A.
Solution: Download the V2 Version, put it in your additional libs folder.

Ok. Sorry, I may have messed with the Library and Additional folder. Thanks.

Hello,
I also encounter this error:

Maven artifact not found: com.google.android.gms/play-services-maps

I think I have reproduced the tutorial except for a part concerning Firebase. I downloaded the json file but I do not know how to declare it in my code for it to be taken into account. Can this lack of statement generate the error above? Thank you in advance for your help.

 

[DonManfred]

You should create a new Thread for your question.

The B4A Installation Steps are described here. Check them. Especially the use of the B4A SDK Manager to download the SDK.

Ok,

I solved my problem. I select my bad api developer console, now that I've selected the correct all works.

Hello. i have the same problem. how had you fix this?

 

[Arnaud]

Hello,

It seems the file "GoogleMaps.zip" in attachment is the version 1.01 and not the version 2.00

So, the Mapfragment1" doesn't' appears in CustomView in the Designer...

Is it normal?

Thanks

 

[Erel]

The correct version is attached to the first post. I guess that you have an older version in the internal libraries folder.

 

[Arnaud]

Yes, internal libraries folder was the problem.

thanks
