eclipse - Where exactly on android emulator app goes? Is it case at max 2 app at a time, if that's the case how to remove? -

-

i have started android dev using eclipse/adt. made couple of apps (hello, android, test) , see them on android (not sure both seem have got install on simulator) enter image description here

enter image description here

what happening whatever app make runs fine not see on emulator. downloaded 2 activity example http://www.mkyong.com/android/android-activity-from-one-screen-to-another-screen/ open project in eclipse , run not see on simulator. first time mobile development might missing obvious.

i noticed having following 2 warning while running app.

warning: data partition in use. changes not persist! warning: cache partition in use. changes not persist!

could reason how resolve it?

i've never encountered limit how many different apps can load emulator, can't speak issue.

removing app easy (pretty phone work).

1) bring app list
2) hit menu button
3) select "manage apps"
4) click on app
5) click on "uninstall"
