How to replace / uninstall Email application from android emulator

Question

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.

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.

Answer 1

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

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.

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.

所有我可以说的是，我也试图找到解决方案，但你可以尝试替代，尝试通过系统应用程序卸妆卸载不必要的应用程序，现在从市场安装类似于相同目的的应用程序，看看它是否工作相同。
