    </activity>

   <activity android:name="com.twoproject.two.TwoAppActivity"
              android:label="twoapp">
        <intent-filter>

In eclipse right click on OneProject>Properties>java Build Path> In right window click Project>Add>TwoProject>OK>OK

Thats it!!! When u install OneProject TwoProject will get installed. Console will show found dependency.

cheers!!

Remove this from Oneproject:

      <activity android:name="com.twoproject.two.TwoAppActivity" 
     android:label="twoapp"> 
         <intent-filter> 
     <action android:name="android.intent.action.MAIN" /> 
     <category android:name="android.intent.category.LAUNCHER" /> 
       </intent-filter> 
      </activity> 

Add this tags to the intent filter of OneProject:

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

Both the applications get installed, I guarantee!!!

add this to your activity tag:

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

now you manifest code will look like:

<?xml version="1.0" encoding="utf-8"?>

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".OneAppActivity"
              android:label="@string/app_name">
    <intent-filter>
       <action android:name="android.intent.action.MAIN" />
       <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
    </activity>

   <activity android:name="com.twoproject.two.TwoAppActivity"
              android:label="twoapp">
        <intent-filter>
           <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

Now it will create two launcher icon on your device.That's what you are asking?

I don't believe you can, as the Android concept of an 'application' (as in the <application> element in the XML file) is pretty much tied to a single .apk file.

However, you can achieve the same effect but simply copying all the activities from TwoProject into OneProject. A single application can have multiple launcher icons so from the user's perspective it'll still look like two runnable things on the launcher. Plus, this way you get to share code and resources. Does that suffice?
