Failure trying to reinstall new Camera.apk to android emulator 2.2

问题

According to this, I tried to modify GLRootView.java and reinstall new Camera.apk; however, some errors show up when I tried to uninstall the old Camera.apk. Do you know what's the issue and how to resolve it?

$ ./adb remount 

remount succeeded

$ ./adb shell rm /system/app/Camera.apk

rm failed for /system/app/Camera.apk, Directory not empty

$ ./adb uninstall com.android.camera 

Failure

reinstall from eclipse

I've got the same error. I think it can be connected with system image size.

Try to start an emulator with parameter -partition-size 150. In my case it solved the issue.

There is a tutorial with pictures "How to install Android market into SDK" describing similar problem.

If that failed for some reason, type in the command prompt:

adb remount
adb shell

and in inside the shell:

cd /system/app
rm Camera.apk

Use it only in the emulator!!!
