Question

I developed an android application with no errors. It is installed in my phone and functioning perfectly but the only problem is, when I’m installing the application. It is installing all the classes in application individually and along with it my main application.

So, how should I prevent all the classes installing individually. please help me.

Answer 1

I am guessing that your AndroidManifest.xml has multiples of this:

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

Which is causing multiple icons to be showed for each Activity
Find all the “extra” ones and delete them. This used to be an issue with the ADT plugin a while back (every time you made a new Activity via the wizard, it would auto add it with launcher attributes), you seem to be on an older version. You should update it.
