如何使用API​​级别为10的Google Maps API v2？

时间：2013-01-10 19:41:21

标签： android google-maps

根据1，发布的代码可用于Android API 12或更高版本。我在具有API级别10（Google API平台2.3.3）的模拟器上尝试了代码，我收到以下着名错误：

E/AndroidRuntime( 429): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example..../com.example....MainActivity}: android.view.InflateException: Binary XML file line #7: Error inflating class fragment

我在下面复制粘贴我的.xml文件。 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >

<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.MapFragment"/>

所以我假设不支持fragment元素......（？）。我在API级别为17的模拟器中尝试了相同的代码，然后我收到了该消息（正如我正在阅读的那样，目前是模拟器的一个问题）：

This app won't run unless you update Google Play Services.

我没有一个真正的设备有17级测试它，但我认为它可能会工作。

上述代码中是否有任何错误专门针对10级？ Google目前支持的代码是什么，以便在API级别为10的Android设备中开发地图？

更新： 更改为FragmentActivity和SupportMapFragment后，我会收到以下信息：

W/dalvikvm( 6718): Unable to resolve superclass of Lmaps/a/du; (406)
W/dalvikvm( 6718): Link of class 'Lmaps/a/du;' failed

2秒后：
Google Maps Android API Authorization failure

更新2： 我改变了项目为android 10构建目标（我有它用于android 4.2）。所以现在我没有看到授权失败）。我还粘贴了来自Google api accesses的api访问权限。

我没有在项目的.properties中启用proguard，即：， # To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home): #proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

# Project target.
target=android-10

答案 0 :(得分：15)

而不是使用com.google.android.gms.maps.MapFragment使用com.google.android.gms.maps.SupportMapFragment，而Activity则必须切换为FragmentActivity，如下面的评论中所述

答案 1 :(得分：6)

我使用下面的代码希望对你充分使用： -

打包并延伸 

import android.support.v4.app.FragmentActivity;
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.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class UserLocation extends FragmentActivity

<强>码 

    android.support.v4.app.FragmentManager fragmentManager = getSupportFragmentManager();
    SupportMapFragment mapFragment = (SupportMapFragment) fragmentManager
            .findFragmentById(R.id.map);
    googleMap = mapFragment.getMap();

适合我。

<强> SupportMapFragment

答案 2 :(得分：1)

对于早期的API，您需要使用SupportmapFragment。请参阅SupportMapFragment docs，基本上使用class="com.google.android.gms.maps.SupportMapFragment"代替class="com.google.android.gms.maps.MapFragment"

答案 3 :(得分：0)

{ 使用此作为代码的参考.. http://www.androidhive.info/2013/08/android-working-with-google-maps-v2/

同样在上面的示例中，必须在清单的元数据标签中使用自己的Api Key 给出了生成Api密钥的指令 }

现在如果你想在android 2.3中实现这个代码

1）首先更改清单

<uses-sdk
    android:minSdkVersion="10"
    android:targetSdkVersion="17" />

然后右键单击＆gt;属性＆gt; Android＆gt; Android 2.3

2）有两个谷歌播放服务库

   a)..\sdk\extras\google\google_play_services_froyo\libproject\google-play-services_lib

   b)..\sdk\extras\google\google_play_services\libproject\google-play-services_lib

如果您正在使用android 2.3 尝试将第一个作为库项目 （您首先需要将其导入为库项目文件＆gt;导入＆gt; ................）

3）然后按照说明here

4）确保您的Google Play服务应用在您的设备上是最新的
