how do i call a make file inside Android.mk

[Mrinal]

I am working on GTV which is basically android.

the Android.mk file gets picked from the build system that does the
needful.

My problem:
I have a application player which is running as a service and another
application discplayer which connects to it and plays the movie.

the player is built differently and it is copied to the appropriate
system/bin folder. It is huge and we intend to only use it as a
external library

android/vendor/videon/player/tools/gtv-discplayer is the structure of
my directory.

now i have the following Android.mk file in the player directory
=============================
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
include $(LOCAL_PATH)/Makefile

.PHONY: libvideonplayer
libvideonplayer:
cd $(LOCAL_PATH)/../../../videon/player && $(MAKE) dib-config install-
bdj all

LOCAL_MODULE := libvideonplayer
include $(call all-subdir-makefiles)
============================

and the following Android.mk is present in the player/tools/gtv-
discplayer
=============================

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

############################################################
LOCAL_STATIC_JAVA_LIBRARIES := videon-lib
LOCAL_MODULE_TAGS := eng user
############################################################

LOCAL_SRC_FILES := $(call all-java-files-under, src)

LOCAL_REQUIRED_MODULES := libvideonplayer

LOCAL_PACKAGE_NAME := Videon

include $(BUILD_PACKAGE)

############################################################
include $(CLEAR_VARS)

LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := \
videon-lib:libs/disc_player_service.jar

include $(BUILD_MULTI_PREBUILT)
====================================

now if I do a 'make libvideonplayer' everything goes fine

but if i do a simple make from the topmost android directory the
dicsplayer app gets built but the player does not. Somehow the
libvideonplayer is not being picked up.
I realize that 'ALL_MODULES' is responsible for getting the
LOCAL_MODULES.

Am I missing something here?

Hi

If Android.mk is not picked form top file, you can add an Android.mk containing below include command at android/vendor/videon/ level.

include $(call first-makefiles-under,$(call my-dir))

Sample file: http://git.omapzoom.org/?p=platform/hardware/ti/omap3.git;a=blob;f=Android.mk;hb=refs/heads/froyo

Thanks Deva,

I think i misdiagnosed the issue
I think the vendor/videon/player/Android.mk file is being picked up.

The question how would i call libvideonplayer target from the top
directory with just calling make?

I think i got it

I have the same Android.mk file earlier in the vendor/videon/player
directory

My problem was that when i do a "make libvideonplayer" the player gets
built
but when i do a plain "make" then the libvideonplayer target is not
picked up

According to android/build/core/build-system.html (I think this file
is only available with GTV distro)

--A plain "make" is the same as "make eng". droid is an alias for
eng.--

so instead for running just "make" i could be having "make droid
libvideonplayer" which serves my purpose.

Although i think this is a workaround. I think android should have a
list of target before and after the main installation.
This way we could pump our custom targets.

You can not do this. 

You have to include some build template, such as $(BUILD_EXECUTABLE), to define a module that uses your LOCAL_MODULE.

You have 2 choices here:

#1 Adapt the original Makefile to an Android.mk, in which you define you own module by including $(BUILD_EXECUTABLE).

#2 Build the executable as a prebuilt executable: that's to say, don't integrate its Makefile into the android build system. Then copy the prebuilt binary (suppose it's called videonplayer) into the source tree and define a prebuilt module:

############################################################

include $(CLEAR_VARS)

LOCAL_PREBUILT_EXECUTABLES := videonplayer

LOCAL_MODULE_TAGS := optional

include $(BUILD_MULTI_PREBUILT)
