open application on install android

I am making an application but i don't want it to be on the Home Screen as a Launcher icon. It holds Background Service.

Is it possible that when the user install the ap开发者_如何学Goplication it opens the screen automatically so that user could enter the Pin Code or password? But that does not need to be on the launcher icon?

Its possible man.. Just remove intent filter tag under tag activity in the manifest file. Declare activity as listed below

<activity android:name=".CallIntents"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
            </intent-filter>
        </activity>
