谷歌地图API V2：应用程序崩溃时我想查看地图 [英] Google maps api v2 : the application crashes when I want to view the map

问题描述

我的工作片段显示谷歌地图。但我一直从应用程序崩溃开始报显示地图时。
我已经有Android的支持-v4和在库的Google Play服务。
这是code代表我的活动：

I am working on fragments to show a google map . But i keep gettin crashes from the app when showing the map. I already have the android-support-v4 and google-play-services in the libs. This is the code for my activity :

package com.example.attijaribank2; 
import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;

public class Votresolde extends FragmentActivity {
static final LatLng HAMBURG = new LatLng(53.558, 9.927);
static final LatLng KIEL = new LatLng(53.551, 9.993);
private GoogleMap map;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_solde);
map =         ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
        .title("Hamburg"));
    Marker kiel = map.addMarker(new MarkerOptions()
        .position(KIEL)
        .title("Kiel")
        .snippet("Kiel is cool")
        .icon(BitmapDescriptorFactory
            .fromResource(R.drawable.ic_launcher)));


    map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));


    map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
    map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));


    map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);    
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_solde, menu);
return true;
}

}

我是什么做错了吗？或者是有关XML文件？

what am I doing wrong ? or is it about the xml file ?

这是XML文件：

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"/>

和logcat的：

报告说，谷歌部份播放服务缺失但我没有导入。

It says ths google play services is missing yet I did Import it .

推荐答案

谷歌Play服务的缺失。

Google Play services is missing.

这意味着，无论你是在其上没有安装谷歌玩模拟器测试

this means that either you are testing on emulator on which Google play is not installed

请检查的官方链接澄清你的疑问：

Please check the official link to clarify your doubt which says:

Note: Google Play services is not supported on the Android emulator — to develop using the APIs, you need to provide a development device such as an Android phone or tablet.
