How to replace / uninstall Email application from android emulator

Is there any way to uninstall/replace the inbuilt application in android emulator so that i can install my customized apps for Mail, Contacts, Music etc.开发者_如何转开发

I have downloaded android 2.2 code for Email application and i want to modify certain things and install.

Please let me know if there is any way.

There's no point in replacing the apps in /system while the emulator is running, since the emulator doesn't save /system anyway.

In order to permanently replace apps in /system, one can edit the system.img file. It's quite easy really. As easy as extracting, moving files around, and compressing it back.

I have done this way:

adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock0 /system
mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /data
rm /system/app/MyAppName.apk
rm -rf /data/data/package_name_here/
mount -o remount,ro -t yaffs2 /dev/block/mtdblock0 /system
mount -o remount,ro -t yaffs2 /dev/block/mtdblock1 /data
pm uninstall package_name_here
exit

Take care points:

You have to provide details of your application:

Line number 4: rm /system/app/MyAppName.apk

Line number 5: rm -rf /data/data/package_name_here/

Line number 8: pm uninstall package_name_here

Done

Launch your emulator, then make sure it is connected via adb, by typing:

adb -e devices

Make /system writable, by typing:

adb -e remount

Backup & remove Email.apk:

adb -e pull /system/app/Email.apk
adb -e rm /system/app/Email.apk

Push you own Email.apk:

adb -e push Email.apk /system/app

That's about it.

All i can say is i am also trying to find the solution but you can try an alternative, try uninstalling unnecessary apps by system app remover and now installing a application similar for the same purpose from market and see if it works the same.
