I heard about editing mainfest, but i can't make them.Please, help me, and don't remove my post. Thanks,
This looks like an answer to your needs: http://androidsnips.blogspot.com/2011/11/create-android-application-with-no.html?m=0
One possible way is removing the line
<category android:name="android.intent.category.LAUNCHER">
from your manifest, which tells Android that the activity you've put it into should appear in the launcher.
HOWEVER, it's not a good idea to hide your application from the launcher, as then the average user won't know how to find it to reconfigure/remove it as necessary.
