Android: automatically choose debug/release Maps v2 api key?

阅读更多关于 Android: automatically choose debug/release Maps v2 api key?

I'm using Google Maps v2 API in my project. In Google Maps v2 the debug/release API key is defined in AndroidManifest.xml . I have seen the link but in that map key is defined in a xml layout file not in AndroidManifest.xml . So can I define both debug and release keys for my project in AndroidManifest.xml ? I want something like this in AndroidManifest.xml : If debug mode: <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="@string/debug_map_api_key"/> If release mode: <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="@string/release_map_api

问题 EDIT: Resolved! In addition to Daniel's answer (saved my life), here's what I did: 1. Replaced the 'MapActivity2' class to a server API key. 2. Let the other keys in the manifest and 'maps_activites.xml. be the android API key 3. Enable the following APIS on Google Developer APIS: Google Maps Android API Google Places API for Android Google Places API Web Service 4. BOOM! It worked. Here's the code to my github repository in any case: https://github.com/bholagabbar/AurumHealthApp I am trying

问题 I am trying to incorporate the new Google Maps Android API v2 into an application using the Android Support Library. I've gone through many iteration to try to get somewhere to work and now I have given up and thought I should ask here. I went to the API Console, created a project, enabled Google Maps API v2 for Android, created a debug KEY as required and pasted it on the manifest. No authentication problems or anything like that. Pretty sure I did this right. In my project's libs folder I

阅读更多关于 Google Maps V2 - Android - Get a list of Markers

问题 I'm trying to get a list Markers(using GMaps V2 for Android) similar to the getOverlays() method I used in GMaps V1.1 for Android here: private MapView mapView; mapView.getOverlays().add(overlay); How can I do something similar to what I did above but with Markers? Any help would be appreciated. 回答1: How can I do something similar to what I did above but with Markers?

Add markers dynamically on Google Maps v2 for Android

阅读更多关于 Add markers dynamically on Google Maps v2 for Android

问题 what are the possibilities to add markers dynamically depending on the area of the map which is shown? I have a lot of markers or let´s say my markers need a lot of performance to be rendered, cause they are custom. I implemented it now, that only 40 markers are drawn when a "camerachange" was fired. So at this time i always render 40 new markers when cameraposition was changed. I read about runnable and handler, are their more options? Does someone know which of these possibilities is the

Google Maps API v2 SupportMapFragment inside ScrollView - users cannot scroll the map vertically

阅读更多关于 Google Maps API v2 SupportMapFragment inside ScrollView - users cannot scroll the map vertically

I am trying to put a Google map inside a scroll view, so that the user can scroll down other contents to see the map. The problem is that this scroll view is eating up all the vertical touching events, so the UI experience of map becomes very weird. I know that in V1 of the google map, you could override onTouch, or setOnTouchListener to call requestDisallowInterceptTouchEvent upon MotionEvent.ACTION_DOWN. I have tried to implement the similar trick with V2 to no avail. So far I have tried: Override SupportMapFragment, and inside onCreateView, set a on touch listener for the View call .getView

问题 How can we achieve a map marker icon with vector asset file, the way google shows it like this, programatically: Update: map.addMarker(new MarkerOptions() .position(latLng) .icon(BitmapDescriptorFactory.fromResource(R.drawable.your_vector_asset)) .title(title); this doesnot work when dealing with vector assets.
