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

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

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" >

    android:targetSdkVersion="16" />

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

<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>

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