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):
B4X:
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:
B4X:
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 SubNotes
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.
