Question

我不知道，在我的清单，活动或xml加载地图版本2时我做错了什么，

如果你看到我简洁的logcat，我发现了多个例外，

E/AndroidRuntime(16522): FATAL EXCEPTION: main
E/AndroidRuntime(16522): java.lang.RuntimeException: Unable to start activityComponentInfo{com.production.MyApp/com.project.MyApp.AddEvent.AddEventMapActivity}:

E/AndroidRuntime(16522):  at android.support.v4.app.FragmentActivity.onCreateView(FragmentActivity.java:279)

虽然清单看起来像，

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.production.MyApp"
android:versionCode="3"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />

<uses-permission android:name="android.permission.INTERNET" />

<permission
    android:name=" com.production.MyApp.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

<uses-permission android:name=" com.production.MyApp.permission.MAPS_RECEIVE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" /> 

<application
    android:name="com.project.MyApp.MyApplication"
    android:enabled="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.Light.NoTitleBar" >

   <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="no issue with api_key here" />

和xml，

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

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

</RelativeLayout>

我正在扩展FragmentActivity，

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.map_layout);

    try {
        // Loading map
        initilizeMap();

    } catch (Exception e) {
        e.printStackTrace();
    }

}

/**
 * function to load map. If map is not created it will create it for you
 * */
private void initilizeMap() {
    if (googleMap == null) {
        googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(
                R.id.map)).getMap();

        // check if map is created successfully or not
        if (googleMap == null) {
            Toast.makeText(getApplicationContext(),
                    "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                    .show();
        }
    }
}

Answer 1

您需要将以下内容添加到清单文件

 <meta-data android:name="com.google.android.gms.version"
   android:value="@integer/google_play_services_version" />

将其放在清单的末尾，在Map API密钥元数据标记之后。

查看HERE

这是从上一次修订版13更新到google-play-services的新要求。

Answer 2

您需要在清单中添加以下内容

 ...
    <meta-data android:name="com.google.android.gms.version"  
    android:value="@integer/google_play_services_version" />

</application>

此信息可在logcat错误消息中找到。

以及google play services网站

谷歌地图版本2不适用于片段
