    Try this code instead of above &
    Remember main activity of Application add tag

                 <intent-filter>
                <action android:name="android.intent.action.MAIN" />
               <category android:name="android.intent.category.LAUNCHER" />    
            </intent-filter>

    Your manifest Should be like this

    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.timerdemo2"
    android:versionCode="1"
    android:versionName="1.0" >

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

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".NewProject"
            android:label="@string/title_activity_main" 
             android:screenOrientation="portrait">

        </activity>
        <activity
            android:name=".Timedetails"
            android:label="@string/title_activity_timedetails"
             android:screenOrientation="portrait" >

        </activity>
        <activity
            android:name=".ListActivity"
            android:label="@string/title_activity_list"
             android:screenOrientation="portrait" >

        </activity>
        <activity
            android:name=".MainActivity"
            android:label="@string/title_activity_new_project"
             android:screenOrientation="portrait" >

         <intent-filter>
                <action android:name="android.intent.action.MAIN" />
               <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>
        </activity>
    </application>

</manifest>
