我过去两天一直试图使用v2 API在我的Android应用中使用Google地图,但没有成功.我每次都得到的只是一个
Google Maps Android API(16603): Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).
我已经按照Google的设置教程(https://developers.google.com/maps/documentation/android/start),尝试了多次不同工作区中的不同项目,尝试了不同的Google帐户,在StackOverflow中查看了各种答案和建议,但无济于事.
我正在使用Eclipse 4.2.2和Android SDK Tools 22.01,我已经安装了Google Play服务(第7版),我也已经导入google-play-services_lib到我的工作区并添加了对我的android项目的引用.
这是我的代码:
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.googlemapdemo"

<uses-feature

我的XmL文件像这样:

Log Cat错误:
05-15 17:15:16.255: …我正在努力将谷歌地图集成到我正在处理的应用程序中,到目前为止我还有一段相当不愉快的时间.无论如何,我终于得到了一个显示地图的SupportMapFragment并设置了位置和缩放级别.
到目前为止,这是我的代码的功能部分:
@Override
public void onActivityCreated( Bundle savedInstanceState ) {
super.onActivityCreated( savedInstanceState );
Location location = BundleChecker.getExtraOrThrow( KEY_LOCATION, new Bundle[] { savedInstanceState, getArguments() } );
setLocation( location );
if ( checkGooglePlayServicesStatus() == ConnectionResult.SUCCESS ) {
setMapFragment( new SupportMapFragment() );
getActivity().getSupportFragmentManager().beginTransaction().add( R.id.location_detail_mapFrame, getMapFragment() ).commit();
}
populateAddress();
attachButtonListeners();
Runnable initMap = new Runnable() {
@Override
public void run() {
if ( checkGooglePlayServicesStatus() == ConnectionResult.SUCCESS ) {
try {
GoogleMap map = getMapFragment().getMap();
LatLng latLng = getLocation().getAddress().getLatLng( getActivity() );
CameraUpdate update = CameraUpdateFactory.newLatLngZoom( …这个bug一直存在.(我确保"谷歌地图Android API v2"是打开的.)
这是MainActivity.java:
package com.example.maptest;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
public class MainActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
表现:
<uses-sdk
android:minSdkVersion="17"
android:targetSdkVersion="17" />
<permission
android:name="com.example.maptest.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> …我有一个工作谷歌地图v2应用程序,但由于某些情况,我不得不更改我的调试密钥库.当然,我已将新的SHA-1指纹添加到我的Google API帐户中允许的Android设备列表中.
地图不再显示,仅显示灰色背景上的缩放和中心按钮.ADB日志中弹出以下错误:
05-21 18:11:42.903: I/Google Maps Android API(15747): Failed to contact Google servers. Another attempt will be made when connectivity is established.
05-21 18:11:43.093: E/Google Maps Android API(15747): Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).
我在stackoverflow上浏览了几个类似的问题,但似乎没有解决我自己的问题.
这是我做过/检查过的:
我想补充一点,我的旧应用程序版本与原始调试密钥库仍然可以正常工作.
任何帮助表示赞赏.谢谢 !
