The error I am getting: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.coldice.plotfinder/com.coldice.plotfinder.MapFragment}: java.lang.NullPointerException at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2668) at android.app.ActivityThread

问题 I'm looking for a better way at drawing a route on google map v2 on android in real time.

Could not contact Google servers. 04-25 15:08:42.082: W/Google Maps Android API(19139): Please add <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> into AndroidManifest.xml to ensure correct behavior

问题 So I've looked over many questions on this issue but have failed to find a solution. Following is the error I'm currently receiving when I try to use the Google Maps Android API. 02-28 11:17:07.166 7445-7653/com.test.drawernav E/b: Authentication failed on the server. 02-28 11:17:07.166 7445-7653/com.test.drawernav E/Google Maps Android API: Authorization failure. Please see https://developers.google.com/maps/documentation/android/start for how to correctly set up the map. 02-28 11:17:07.176

问题 I created first version of my application using Google Maps Android v1 API. But now When I released my application for second version, Google map stopped working. I think it's because of it's deprecated. So now I'm trying to create sample Android application to use Google Map using this link. First I was trying with this code But as I suggested to use SupportMapFragment with FragmentActivity, I changed my xml code to <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

问题 I'm trying to implement google-play-services library and it seems to me I'm doing everything right.

问题 I am using Xamarin and I am wanting to create a CustomWindowAdapter that implements a GoogleMap.InfoWindowAdapter interface. I have tried this so far: public class CustomWindowAdapter : InfoWindowAdapter { } I am getting this error: Error CS0246: The type or namespace name 'InfoWindowAdapter' could not be found (are you missing a using directive or an assembly reference?)
