</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();

    }


}

我将 google_play_services 库引用到我的项目中，在我的库中添加了 google_play_service 和 android.support.v4 jar 文件....如果我仍然缺少任何东西，请指导....

I gave reference of google_play_services lib to my project added google_play_service and android.support.v4 jar files in my lib....Please if i m still missing anythng please guide....

我在 maifest 中添加了 api 密钥，请参阅上面的已编辑...

I have api key which i have added in maifest see above its edited now...

这里是我手机日志中的错误跟踪

推荐答案

Whoo...在挠了马头这么久之后我终于找到了解决方案首先，我按照其文档使用 DDMS 对真实设备进行了调试，这非常棒，然后我发现了以下错误

Whoo...after scratching ma head for so long atlast i got the solution first i did debugging with real device using DDMS following its documentation which is fabulous then i discovered the following error

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

然后在几行代码之后出现了另一个引人注目的错误

and then after few more lines of code there was another error which was eye catching

12-12 15:08:29.458: E/AndroidRuntime(26382): Caused by: 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 密钥代码是上述错误指出的清单而不是应用程序的子项，然后我将清单纠正为以下

and then i realised that my api key code is a child of manifest not application which the above error pointed out and then i rectified my manifest to following

<?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="android.permission.ACCESS_CORSE_LOCATION" />

<uses-feature android:glEsVersion="0x00020000" android:required="true"/>
 <permission
     android:name="com.example.emeterfinalapp.permission.MAPS_RECEIVE"
     android:protectionLevel="signature"/>
<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>

然后它就像缩放一样，一切都完美无缺......使用真实设备进行调试有很大帮助......

and then it went like a zoom and everythng worked just perfectly...Debugging with real device helped a lot...
