How to convert Android.mk to CMake.txt? - android

This is how my Android.mk file looks like. What is the equivalent CMakeLists.txt? I am struggling to find libhardware in CMake. Any ideas?
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := libtestLed
LOCAL_SRC_FILES := testled.cpp
LOCAL_C_INCLUDES := $(call include-path-for, libhardware)/hardware
LOCAL_SHARED_LIBRARIES += \
libandroid_runtime \
libcutils \
liblog \
libhardware \
LOCAL_MODULE_TAGS := optional
LOCAL_VENDOR_MODULE := true
include $(BUILD_SHARED_LIBRARY)


the line you mentioned would be
target_link_libraries(testLed hardware)

How to import a .so Library in Android.mk when i build APK

I have this problem: I have to build my app using the Android.mk file and I have to insert the library "libcom_google_ase_Exec.so" inside the final apk, but I can't do it. What I get is an APK that doesn't contain the library and therefore the app doesn't work.
The code for the Android.mk I'm currently using is:
#ifneq ($(TARGET_BUILD_PDK), true)
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := com_google_ase_Exec
LOCAL_SRC_FILES := app/src/main/jniLibs/armeabi/libcom_google_ase_Exec.so

include $(BUILD_MULTI_PREBUILT)
#include $(call all-makefiles-under, $(LOCAL_PATH))
#endif
The folder structure within my project is as follows:
In the root i have:
--> /app and Android.mk
In the app folder i have:
--> app/src/main/jniLibs/armeabi/libcom_google_ase_Exec.so
How can i change the Android.mk file to import the .so library in the final APK?

I solved in this way, i build a 64bit version.
If u need a 32bit version u can uncomment all LOCAL_MULTILIB = 32.

Any help will appreciate

If you use LOCAL_MODULE := libjni_terminal in any other project this error will happen.
When using the same LOCAL_MODULE name in different places lead to problems while creating and accessing intermediate files.

How to compile AIDL files with android make file?

I need to compile a android project with make file, but it seems that cannot find aidl files.
here is my Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
LOCAL_OVERRIDE_SRC_FILES := $(call all-java-files-under, devices/$(TARGET_DEVICE))
LOCAL_SRC_FILES := $(call all-java-files-under, SDK src) \
src/com/skyworth/skyappstore/aidl/AppStoreCallBackAIDL \
src/com/skyworth/skyappstore/aidl/AppStoreServiceAIDL \
LOCAL_SRC_FILES := $(foreach f,$(LOCAL_SRC_FILES), \
$(if $(findstring $(f),$(LOCAL_OVERRIDE_SRC_FILES)),,$(f)))
# This is the target being built.
LOCAL_PACKAGE_NAME := APPStore
LOCAL_CERTIFICATE := shared
LOCAL_STATIC_JAVA_LIBRARIES := android fastjson jackson ksoap2 layoutlib tdcode
LOCAL_PROGUARD_ENABLED := disabled
include $(BUILD_PACKAGE)
include $(CLEAR_VARS)
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := android:android.jar \
fastjson:fastjson-1.1.32.jar \
jackson:jackson-all-1.9.8.jar \
ksoap2:ksoap2-android-assembly-3.0.0-jar-with-dependencies.jar \
layoutlib:layoutlib.jar \
tdcode:tdcode.jar
include $(BUILD_MULTI_PREBUILT)
include $(call all-makefiles-under,$(LOCAL_PATH))
this returns that package com.skyworth.skyappstore.aidl does not exist, com.skyworth.skyappstore.aidlis the place where I place my aidl file.
So how to change the make file to compile this project right

Are AppStoreCallBackAIDL and AppStoreServiceAIDL aild files? Maybe you can change
LOCAL_SRC_FILES := $(call all-java-files-under, SDK src) \
src/com/skyworth/skyappstore/aidl/AppStoreCallBackAIDL \
src/com/skyworth/skyappstore/aidl/AppStoreServiceAIDL \
to this:
LOCAL_SRC_FILES := $(call all-java-files-under, SDK src) \
src/com/skyworth/skyappstore/aidl/AppStoreCallBackAIDL.aidl \
src/com/skyworth/skyappstore/aidl/AppStoreServiceAIDL.aidl \

how to config android.mk when i need to export several native library

Now i export one native library and my folder is like this :
JNI\ANN*.cpp.
android.mk file is like this:
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../
LOCAL_MODULE := libann
LOCAL_LDLIBS := -llog
NDK_TOOLCHAIN_VERSION := clang
LOCAL_CPPFLAGS += -std=c++11
LOCAL_SRC_FILES := \
ANN.cpp \
bd_pr_search.cpp \
bd_tree.cpp \
kd_pr_search.cpp \
kd_split.cpp \
kd_util.cpp \
bd_fix_rad_search.cpp \
bd_search.cpp \
brute.cpp \
kd_fix_rad_search.cpp \
kd_search.cpp \
kd_tree.cpp \
kd_dump.cpp \
perf.cpp\
sample.cpp
include $(BUILD_SHARED_LIBRARY)
Now i want to add some other cpp files and export another native lib.
for example, i add two files: graph.h,dijkstra,cpp
how should i config the android.mk file?

android-ndk Adding static libraries to the android.mk

I have three static libraries from a framework that I want to use in my project. These libraries are called libtinySAK_armv7-a.a, libtinyNET_armv7-a.a and libtinyHTTP_armv7-a.a. I have placed them in the same folder as the Android.mkandApplication.mk.
My native code is dependent on them so I want to include them in my shared library.
From what I've read on stackoverflow and google'd I believe the android.mk is supposed to look something like this:
# TINYSAK
include $(CLEAR_VARS)
LOCAL_MODULE := tinySAK
LOCAL_SRC_FILES := libtinySAK_armv7-a.a
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/../../../doubango/tinySAK/src/
include $(PREBUILT_STATIC_LIBRARY)
# TINYNET
include $(CLEAR_VARS)
LOCAL_MODULE := tinyNET
LOCAL_SRC_FILES := libtinyNET_armv7-a.a
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/../../../doubango/tinyNET/src/
include $(PREBUILT_STATIC_LIBRARY)
# TINYHTTP
include $(CLEAR_VARS)
LOCAL_MODULE := tinyHTTP
LOCAL_SRC_FILES := libtinyHTTP_armv7-a.a
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/../../../doubango/tinyHTTP/include/
include $(PREBUILT_STATIC_LIBRARY)
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := libtest
LOCAL_SRC_FILES := \
../../test/stack.cpp \
../../test/main.cpp
LOCAL_C_INCLUDES := \
$(LOCAL_PATH)/../../test/include/ \
$(LOCAL_PATH)/../../../doubango/tinyHTTP/include/ \
$(LOCAL_PATH)/../../../doubango/tinySAK/src/ \
$(LOCAL_PATH)/../../../doubango/tinyNET/src/
LOCAL_STATIC_LIBRARIES := \
tinySAK \
tinyNET \
tinyHTTP
include $(BUILD_SHARED_LIBRARY)
My Application.mk:
APP_STL := stlport_static
APP_ABI := armeabi-v7a
The error I get upon compilation("ndk-build" from project dir) is
jni/Android.mk:tinySAK: LOCAL_SRC_FILES points to a missing file
And I suppose the other 2 libraries also fail. Why cannot it find them?
Besides that, is there any other errors I've made in the makefile?
Thanks

Nevermind, I solved it.
I declared the "LOCAL_PATH" in the beginning of the make-file only. Otherwise it would look for the libs in the ndk-folders.

Try LOCAL_LDLIBS instead of LOCAL_SRC_FILES.
