Android:Google地图未显示 [英] Android: Google Maps not displaying

问题描述

我正在尝试显示Google地图.我可以看到背景(浅灰色背景，小图块，左下角的Google徽标)，所以我知道我已经接近了.但是，没有显示实际的地图.在LogCat中，我看到此消息一遍又一遍:

I'm trying to get a google map to display. I can see the background (light gray background, small tiles, Google logo in the lower left), so I know that I'm close. However, there is no actual map displayed. In the LogCat, I see this message repeating over and over:

05-14 13:28:17.926:W/System.err(27458):在 android_maps_conflict_avoidance.com.google.googlenav.datarequest.DataRequestDispatcher $ DispatcherServer.run(DataRequestDispatcher.java:1702)

05-14 13:28:17.926: W/System.err(27458): at android_maps_conflict_avoidance.com.google.googlenav.datarequest.DataRequestDispatcher$DispatcherServer.run(DataRequestDispatcher.java:1702)

我正在将Google Maps api 2与系留电话一起使用，以运行2.3.4进行测试.

I'm using Google maps api 2 with a tethered phone for testing that is running 2.3.4.

有人知道这可能是什么造成的吗?谢谢！

Anyone know what might be causing this? Thanks!

package com.example.maptest;
import android.os.Bundle;
import com.google.android.maps.MapActivity; 
import com.google.android.maps.MapController; 
import com.google.android.maps.MapView;

public class MyMapActivity extends MapActivity {   

  private MapView mapView;   
  private MapController mapController;

   @Override   public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.map_layout);
     mapView = (MapView)findViewById(R.id.map_view);
   }

   @Override   
   protected boolean isRouteDisplayed() {
     return false;   
   }

推荐答案

此问题通常与用于对清单进行签名的map API密钥有关.看看这篇文章和

This problem is usually related to the map API key used to sign manifest. Take a look at this post and this one which describe the same error you are experiencing. In both cases it is because the API key they used was created with the wrong keystore. You need to make sure you use your debug keystore when you create an API key in the Google API console if you are going to be testing from eclipse.
