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

由 那年仲夏 提交于 2019-11-26 12:18:50
问题 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

Android map v2 zoom to show all the markers

由 喜夏-厌秋 提交于 2019-11-26 11:26:35
I have 10 markers in the GoogleMap . I want to zoom in as much as possible and keep all markers in view? In the earlier version this can be achieved from zoomToSpan() but in v2 I have no idea how about doing that. Further, I know the radius of the circle that needs to be visible. andr You should use the CameraUpdate class to do (probably) all programmatic map movements. To do this, first calculate the bounds of all the markers like so: LatLngBounds.Builder builder = new LatLngBounds.Builder(); for (Marker marker : markers) { builder.include(marker.getPosition()); } LatLngBounds bounds =

Blue dot and circle is not shown on MyLocation using android fused location api

由 六眼飞鱼酱① 提交于 2019-11-26 11:23:57
I was using LocationManager to track the user current location, Now after changing location manager to FusedLocation API, the blue dot and circle is not shown even after setting map.setMyLocationEnabled(true) . I can see the current location icon on top right corner in my map fragment but clicking on it does nothing. I reverted my code to LocationManager now i am able to see the blue dot pointing to my current location. what could be wrong using Fused Location API.

Display toolbar for Google Maps marker automatically

由 夙愿已清 提交于 2019-11-26 10:35:51
问题 I have a marker and when I open the map it shows the marker. When I click on it it shows the title and a toolbar which includes two buttons on the bottom right of the map which let me launch intents to navigate to the marker or show it in google maps. I would like to have these displayed automatically when the map is opened rather than having the user to click on the marker. Like this :-) ... I can\'t seem to work out how to do this. I have tried: // create marker MarkerOptions marker = new
