For apps you don't need,

/out/target/product/m801/system/app Delete the corresponding apk,
To/packages/apps find the corresponding source code, modify. mk
and then recompile.

Next time take a moment to ponder:
Systemserver.java removing unwanted system services
INIT.RC removal of programs that do not need to be relied upon
Preload masking unwanted resources and classes
Google Service
3d OpenGL, Rendscript

Add the custom apk with source 1 copy android.mk from/packages/app/calendar to your project and modify the content:

Local_package_name: = AutoRun
Autorun is the name of his app.

2 Modify/BUILD/TARGET/PRODUCT/GENERIC_NO_TELEPHONY.MK, add your own apk name:

(android2.2 version modified is generic.mk)

The source that contains the android.mk is stacked to

Android4.3/packages/apps

3 compiling

command line to the project root directory, execute:

SOURCE build/envsetup.sh
Choosecombo (select default Direct carriage return)
Make-j2

There are also said direct so that I have no test:

Make clean
Make
When the compilation is complete, start the virtual machine:
./EMULATOR-AVD Androidname-system Out/target/product/generic/system.img

Methods for compiling individual modules

$.build/envsetup.sh
MMM packages/apps/contacts/sample Compile Contact
This generates
out/target/product/generic/data/app/contactstests.apk
out/target/product/generic/system/app/contacts.apk
Make Snod Regenerate system.img

Third-party APK compilation

Using YAFFS2
There is no time to do it today, next time to see the concrete way.
