Google Map Android API V2应用程序崩溃

Question

我使用的是Eclipse helios和Android
4.1.2，我已按照以下文档https://docs.google.com/document/pub?id=19nQzvKP-
CVLd7_VrpwnHfl-
AE9fjbJySowONZZtNHzw
进行操作，并完全按照了教程中的描述进行了编码。我在模拟器上的应用程序显示“除非您更新Google
Play服务，否则该应用程序将无法运行”，但在实际设备（索尼Xperia）上它已更新了Google
Play服务的更新版本，并发出“应用程序已停止运行”的提示。欢迎提供帮助。

这是我的清单

这是我的main.xml

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

        <LinearLayout android:id="@+id/zoom"

            android:layout_alignParentTop="true"
            android:text="@string/mapbuttontext" />

</RelativeLayout>

这是我的活动

    package com.example.emeterfinalapp;

        import android.os.Bundle;
        import android.support.v4.app.FragmentActivity;

        import com.google.android.gms.common.GooglePlayServicesUtil;
        import com.google.android.gms.maps.GoogleMap;
        import com.google.android.gms.maps.SupportMapFragment;

        public class SelectLocation extends FragmentActivity  {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_select_location);
        // Show the Up button in the action bar.
        getActionBar().setDisplayHomeAsUpEnabled(true);
                                           GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

        GoogleMap map = ((SupportMapFragment)          getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

    }


}

我给我的项目提供了google_play_services
lib的引用，在我的lib中添加了google_play_service和android.support.v4
jar文件。如果我仍然缺少任何内容，请指导…。

我有我最明显添加的api密钥，请参见上面对其进行编辑…

amd这是我电话记录中的错误跟踪

Answer 1

o …经过长时间的摸索，我终于找到了解决方案，我按照DDMS的文档进行了操作，使用DDMS在真实设备上进行了调试，然后发现了以下错误

12-12 15:08:29.458: E/AndroidRuntime(26382): java.lang.RuntimeException: Unable to start     activity ComponentInfo{com.example.emeterfinalapp/com.example.emeterfinalapp.SelectLocation}:     android.view.InflateException: Binary XML file line #17: Error inflating class fragment

再经过几行代码后，又出现了另一个错误

12-12 15:08:29.458: E/AndroidRuntime(26382): Caused by: html" target="_blank">java.lang.RuntimeException: API key not found.  Check that <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml

然后我意识到我的api密钥代码是清单错误的子项，而不是上面错误指出的应用程序，然后我将清单更正为

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.emeterfinalapp"
android:versionCode="1"
android:versionName="1.0" >


<uses-sdk
    android:minSdkVersion="11"
    android:targetSdkVersion="16" />

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

<uses-permission  android:name="com.example.emeterfinalapp.permission.MAPS_RECEIVE"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission  android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>


<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

     <uses-library android:name="com.google.android.maps"/>
    <activity
        android:name="com.example.emeterfinalapp.EmeterMainActivity"
        android:configChanges="orientation|keyboardHidden|screenSize"
        android:label="@string/app_name"
        android:theme="@style/FullscreenTheme" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="com.example.emeterfinalapp.EnterLocationActivity"
        android:label="@string/title_activity_enter_location"
        android:parentActivityName="com.example.emeterfinalapp.EmeterMainActivity" >
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.example.emeterfinalapp.EmeterMainActivity" />
    </activity>

    <activity
        android:name="com.example.emeterfinalapp.SelectLocation"
        android:label="@string/title_activity_select_location"
        android:parentActivityName="com.example.emeterfinalapp.EnterMainActivity" >
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.example.emeterfinalapp.EnterMainActivity" />
    </activity>

     <meta-data
   android:name="com.google.android.maps.v2.API_KEY"
   android:value="my api key"/>
</application>

然后就像变焦一样，一切都工作得非常完美…使用真实设备进行调试很有帮助…
