working with Android library projects in android build environment

[James]

Hey all,

I have an android library project that my main project compiles
against. In the past, I used ant but I want it to be compiled with
the rest of my custom ROM when I build...its in packages/apps/MyApp
and packages/apps/MyAppLib ... how do I tell MyApp to use MyAppLib in
the Android.mk file?

Thanks,
James

p.s. I'm referring to the type of library project discussed here:
http://developer.android.com/guide/developing/other-ide.html#libraryProject

First in packages/apps/MyAppLib/Android.mk you define your library module, which I believe should be a static java library.

Then reference it in your MyApp's Android.mk by LOCAL_STATIC_JAVA_LIBRARIES.
See http://source.android.com/porting/build_cookbook.html

Hey Ying,

Thanks for your reply.  When I do that, I get "package R does not exist" errors because it doesn't compile the resources in my Android Library.  Here is my Android.mk:

  LOCAL_PATH := $(call my-dir)
  include $(CLEAR_VARS)

  # Build all java files in the java subdirectory
  LOCAL_SRC_FILES := $(call all-java-files-under, src)

  LOCAL_MODULE := MyAppLib
  include $(BUILD_STATIC_JAVA_LIBRARY)

Thanks,
James

We are not able to put resources into a library yet...

You have to move the resource into your apps' project.

Have not tried the solution myself, but it looks like the way to go. In AOSP, there are two interesting projects:

packages/apps/Email and frameworks/ex/chips. The latter being used as an Android library for the first one. 

Take a look in their Android.mk build files for details. The trick is LOCAL_AAPT_FLAGS and referencing /chips/res folder in the build of the Email project.

Good luck with trying though

It works perfectly
