For apps you don't need,
/out/target/product/m801/system/app Delete the appropriate apk.
Go to/packages/apps to find the corresponding source code. Change. mk
And then compile it again.
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 shielding resources and classes that are not required
Google Service
3d OpenGL, Rendscript
Add your own definition of apk with source code of 1 copy android.mk from/packages/app/calendar to your own project. and change the content:
Local_package_name: = AutoRun
Autorun is the name of his app.
2 Change/build/target/product/generic_no_telephony.mk, add your own apk name:
(android2.2 version number was changed by GENERIC.MK)
Put the source code that includes the ANDROID.MK
Android4.3/packages/apps
3 compiling
command line to the project root folder, run:
SOURCE build/envsetup.sh
Choosecombo (select default Direct carriage return)
Make-j2
There are also those who say this directly. I don't have a 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/Demo sample compile Contact
This generates
out/target/product/generic/data/app/contactstests.apk
out/target/product/generic/system/app/contacts.apk
Make Snod generates SYSTEM.IMG again
Third-party APK compilation
Using YAFFS2
There is no time for this today. See the detailed procedure again next time.
