Android : Eliminating Complete Action Using Dialog

I have 2 apps and both integrate a package containing an activity. My problem is that when I launch any one app, and when it calls the activity inside the package, it shows me a dialog:

Complete action using:

App1

App2

I want to eliminate this dialog, so it just launches the activity from its own integrated package.Currently, my AndroidManifest.xml contains for the package activity:

<intent-filter>
<action android:name="com.example.test.TestActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
