It because you are applying </intent-filter> to all activities instead to main, just make changes like below

    <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=".MainActivity"
                android:label="@string/title_activity_main" 
                 android:screenOrientation="portrait">
                <intent-filter>
                <action android:name="android.intent.action.MAIN" />
            </intent-filter>
            </activity>

            <activity
                android:name=".NewProject"
                android:label="@string/title_activity_new_project"
                 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>

        </application>

    </manifest>

There is quite a bit of documentation on intent Filter

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>

Change your Intent Filters , the MAIN/LAUNCHER intent filter essentially tells android that the activity is the app's starting activity instead of using : 

<action android:name="android.intent.action.MAIN" />

Use :

<action android:name="android.intent.action.VIEW" />
