I am building some hardware tests for Android. I have an Android.mk file which builds these executables one-by-one, using a block of makefile code for each, as shown below:
##### shared #####
LOCAL_PATH := $(my-dir)
##### test_number_one #####
test_name := test_number_one
include $(CLEAR_VARS)
LOCAL_CFLAGS := $(commonCflags)
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../
LOCAL_MODULE_TAGS := optional eng
LOCAL_SHARED_LIBRARIES := some_library some_other_library
LOCAL_MODULE := $(test_name)
LOCAL_SRC_FILES := tests/$(test_name)/$(test_name).c
include $(BUILD_EXECUTABLE)
##### test_number_two #####
test_name := test_number_two
include $(CLEAR_VARS)
LOCAL_CFLAGS := $(commonCflags)
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../
LOCAL_MODULE_TAGS := optional eng
LOCAL_SHARED_LIBRARIES := some_library some_other_library
LOCAL_MODULE := $(test_name)
LOCAL_SRC_FILES := tests/$(test_name)/$(test_name).c
include $(BUILD_EXECUTABLE)
As you can see, the majority of the code is repeated for each test (between include $(CLEAR_VARS) and include $(CLEAR_VARS)). I would like to simplify this such that I have a list of test names and a section of makefile code which is 'called' for each one. I don't care if that code must be split into another file. Here's some python-esque pseudocode to demonstrate what I am going for:
##### shared #####
LOCAL_PATH := $(my-dir)
##### test_number_one #####
test_names := test_number_one test_numer_two
for each item in test_names:
include $(CLEAR_VARS)
LOCAL_CFLAGS := $(commonCflags)
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../
LOCAL_MODULE_TAGS := optional eng
LOCAL_SHARED_LIBRARIES := some_library some_other_library
LOCAL_MODULE := $(item)
LOCAL_SRC_FILES := tests/$(item)/$(item).c
include $(BUILD_EXECUTABLE)
Is this possible in Android.mk files? How can it be done?
You should be able to do something like
define my_add_executable
include $(CLEAR_VARS)
LOCAL_CFLAGS := $(commonCflags)
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../
LOCAL_MODULE_TAGS := optional eng
LOCAL_SHARED_LIBRARIES := some_library some_other_library
LOCAL_MODULE := $1
LOCAL_SRC_FILES := tests/$1/$1.c
include $(BUILD_EXECUTABLE)
endef
test_names := test_number_one test_numer_two
$(foreach item,$(test_names),$(eval $(call my_add_executable,$(item))))
We have similar construction in our project to include multiple prebuilt libraries.

I have 2 Android.mk files with the first one building a bunch of libraries and the second one builds another library, but needs the first one to be complete before kicking off it's own build. Is there any way to make sure this happens?
This is what I've tried so far:
LOCAL_ADDITIONAL_DEPENDENCIES := path/to/folder/for/android1.mk
Order of listing of these Android.m files (1 & 2)
Adding LOCAL_SHARED_LIBRARIES := a.so b.so ...
But, none of these have helped so far

LOCAL_ADDITIONAL_DEPENDENCIES := /path/to/folder/where/Android1.mk/resides
LOCAL_SHARED_LIBRARIES += \
lib_a \
lib_b
include $(BUILD_SHARED_LIBRARY)
The caveat is that abc.c/xyz.c doesn't make any calls in lib_a.so/lib_b.so/lib_z.so. But, I'm generating a script (in Android2.mk) and for that, require all the libraries (in Android1.mk) to be built prior
Found a way to achieve this:
# List out all the dependencies here
INTERMEDIATE_TARGET := \
lib_1
lib_2
generate.abc: $(INTERMEDIATE_TARGET)
I have a shared lib (ex. libcrypto.so), but don't have header files.
Can I use this lib in other module?
I tried to use LOCAL_EXPORT_C_INCLUDES to export header files, but It doesn't work.
This is prebuilt module:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := libcrypto
LOCAL_SRC_FILES := prebuilt/$(TARGET_ARCH_ABI)/libcrypto.so
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
include $(PREBUILT_SHARED_LIBRARY)
And, this is module used libcrypto:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES += test.c # include "openssl/crypto.h"
LOCAL_C_INCLUDES += $(crypto_PATH)/include
LOCAL_SHARED_LIBRARIES += libcrypto
LOCAL_MODULE := libtest
LOCAL_MODULE_TAGS := optional
LOCAL_ARM_MODE := arm
LOCAL_PRELINK_MODULE := false
include $(BUILD_SHARED_LIBRARY)
This is libcrypto module (boringssl):
LOCAL_PATH := $(call my-dir)
# Target shared library
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE := libcrypto
LOCAL_EXPORT_C_INCLUDE_DIRS := $(LOCAL_PATH)/src/include
LOCAL_ADDITIONAL_DEPENDENCIES := $(LOCAL_PATH)/Android.mk $(LOCAL_PATH)/crypto-sources.mk
LOCAL_SDK_VERSION := 9
LOCAL_CFLAGS += -fvisibility=hidden -DBORINGSSL_SHARED_LIBRARY -DBORINGSSL_IMPLEMENTATION -DOPENSSL_SMALL -Wno-unused-parameter
# sha256-armv4.S does not compile with clang.
LOCAL_CLANG_ASFLAGS_arm += -no-integrated-as
LOCAL_CLANG_ASFLAGS_arm64 += -march=armv8-a+crypto
include $(LOCAL_PATH)/crypto-sources.mk
include $(BUILD_SHARED_LIBRARY)
EDIT: Added boringssl module. I actually used #include "openssl/crypto.h" in test.c
Usually, you find crypto.h under include/openssl. So, in your case, either change the #include statement in test.c
#include "openssl/crypto.h"
Or (less recommended), edit
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include/openssl

clean project and I'm trying to cross compile NDK then show given below error:
/Volumes/Work/Android/Projects/app/src/main/jni/../prebuild/libz.a: error adding symbols: File in wrong format
clang++: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [/Volumes/Work/Android/Projects/app/src/main/obj/local/arm64-v8a/libcurl-ndk.so] Error 1
Its working on 32 bits fine but 64 bit its show error
Thanks in advance
You're using one prebuilt for all ABIs. You need one prebuilt for each ABI you target. The typical way to write a prebuilt module is like this:
include $(CLEAR_VARS)
LOCAL_MODULE := libz
LOCAL_SRC_FILES := ../prebuild/$(TARGET_ARCH_ABI)/libz.a
LOCAL_EXPORT_C_INCLUDES := ../prebuild/include/
include $(PREBUILT_STATIC_LIBRARY)
Then you can have prebuild/armeabi-v7a/libz.a, prebuild/arm64-v8a/libz.a, etc. Disable ABIs you don't want to build for (or don't have prebuilts for) using APP_ABI in your Application.mk.
I am trying to use pjsip on android.. after ./configure-android and make dep and make commands, static libraries were generated 13 of them.

I wrote a simple one line c file that only includes a header file inside include folder. Then i run ndk-build from the project directory and get no such file for the header file which is present inside the include folder. There is no application.mk.. What am i missing?
EDIT
the '.' represents the current directory.. "include" folder is inside jni folder
There are several issues here:
1) Each prebuilt static library should have its own module definition, i.e. your Android.mk should look like:
include $(CLEAR_VARS)
LOCAL_MODULE := libpj
LOCAL_SRC_FILES := libpj-arm-unknown-linux-androideabi.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := libpjlib-util
LOCAL_SRC_FILES := libpjlib-util-arm-unknown-linux-androideabi.a
include $(PREBUILT_STATIC_LIBRARY)
... etc
Note that the module name doesn't have to be exactly the same as the file path, which makes things a little clearer for the rest.
2) That '.' will refer, at build time, to the current directory where you invoke ndk-build, you need to use $(LOCAL_PATH)/include instead to refer to the right include path (assuming your Android.mk is under jni/ too). I.e.:
include $(CLEAR_VARS)
LOCAL_MODULE := dummy_pjsip_jni_module
LOCAL_SRC_FILES := dummy_pjsua.c
LOCAL_EXPORT_C_INCLUDES += $(LOCAL_PATH)/include
LOCAL_C_INCLUDES += $(LOCAL_PATH)/include
LOCAL_STATIC_LIBRARIES := libpj libpjlib-util libpjmedia libpjmedia-audiodev \
libpjmedia-codec libpjmedia-videodev libpjnath \
libpjsdp libpjsip libpjsip-simple libpjsip-ua \
libpjsua2 libpjsua

I'd like to create two .so file within a single .mk file. But the following codes fails because there should not be a space in LOCAL_MODULE. So is there a way out?
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := gpio hello-jni
LOCAL_CFLAGS := -Werror
LOCAL_SRC_FILES := gpio.c hello-jni.c
LOCAL_LDLIBS := -llog
include $(BUILD_SHARED_LIBRARY)
I just got it works using the following codes.
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := gpio
LOCAL_CFLAGS := -Werror
LOCAL_SRC_FILES := gpio.c
LOCAL_LDLIBS := -llog
include $(BUILD_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := h ello-jni
LOCAL_CFLAGS := -Werror
LOCAL_SRC_FILES := hello-jni.c
LOCAL_LDLIBS := -llog
include $(BUILD_SHARED_LIBRARY)
