Can one Android app have more than one icon in app launcher?

Why not! Just add this to your favorite AndroidManifest.xml:

<application>
<activity android:name="AActivity" android:icon="@drawable/a_icon" android:launchMode="singleTask"
android:screenOrientation="portrait"
android:label="@string/a_name"  android:theme="@android:style/Theme.Translucent.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="BActivity" android:icon="@drawable/b_icon" android:launchMode="singleTask"
android:screenOrientation="portrait"
android:label="@string/b_name"  android:theme="@android:style/Theme.Translucent.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="CActivity" android:icon="@drawable/c_icon" android:launchMode="singleTask"
android:screenOrientation="portrait"
android:label="@string/c_name"  android:theme="@android:style/Theme.Translucent.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity></application>

and that's it. You'll get s single app with three different app icons: a_icon, b_icon, c_icon.

  }
}

How do you delete a downloaded timesheet in QuickBooks so it can be resubmitted?

You need to delete the incorrect time from your QuickBooks first, and then ask this employee to use the following utility to re-submit his/her timesheet for that week.

This utility changes the status for a week's worth of time activities. The employee time trackers must perform the steps to update their own activities.

1. Login to the Row View and navigate to the week of time activities you would like to update the status for.

2. Click the Switch to Calendar View link.

3. From the Calendar View, click the Switch to Row View link.

4. Change the following parameters to the end of the URL of the page to invoke the repair utility:

&cmd=repair&status= submitted

The full URL should look something like this:

https://timetracking.quickbooks.com/j/tts/tts_timesheetweek=1222714800000&ampcmd=repair&ampstatus=subm...

5. When done adjusting the URL, press the Enter key on the keyboard to load the next page.

6. If the statuses were successfully updated, you will see a success message on the Timesheet Repair Status page.

7. Click on the Undo Submit button, make the necessary changes to the timesheet, and then submit the timesheet again.
