I am importing a .aar file as a dependency in my android project and have added this to Android.mk file.
Now internally this file has dependency on some .so files which its not able to pick up automatically.
So I copied all the dependent .so files under the below structure,
app --> libs --> arm64-v8a --> test.so
|
| --> x86 --> test.so
And now I tried several combination of below config in Android.mk file, but the above test.so file is not getting added to the apk generated after building.
.

**include $(CLEAR_VARS)
ifneq (,$(filter $(TARGET_ARCH_ABI), armeabi-v7a x86 arm64-v8a x86_64))
LOCAL_MODULE := Some Name
LOCAL_SRC_FILES := sources/app/libs/$(TARGET_ARCH)/xyz.so //Path of of my local .so file
LOCAL_MODULE_CLASS := SHARED_LIBRARIES
include $(PREBUILT_SHARED_LIBRARY)**
I tried lot of googling and also referred Android Xref, but unable to figure out what I am missing.
Any leads?
LOCAL_PREBUILT_JNI_LIBS = libs/xxxx.so

I have an APK that contains java code and some .so files. I have built the APK in Android Studio and now this APK needs to be part of /system/app/ folder on my custom ROM.
Java code + .so = APK
To include it in system/app/, I am having the below build script in Android.mk file and calling it from device.mk file.
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE := utility
LOCAL_MODULE_CLASS := APPS
LOCAL_CERTIFICATE := platform
LOCAL_SRC_FILES := utility.apk
include $(BUILD_PREBUILT)
After building the image, I find my APK crashing, and the log says "Cannot link executable" and all .so files seeems to be missing.
However, the APK works if I use adb install utility.apk.
Can someone tell me what is that I am missing in the buildscript that is causing .so files not being available.
P.S.: I searched inside /data/data/com.org.utility/, /system/lib/ folders, but no .so files were found.
But if I use adb install, .so files are found inside /data/data/com.org.utility/lib/x86/ folder.
I don't remember in L or M, there is a bug in the build system.
The so in the apk which is built into system/app or system/priv-app cannot release into the system. But the third party app can release there libs by PackageManagerService.
One solution：
1. Released the so in the apk manually.
2. Add so related to the Android.mk, for example:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := test
LOCAL_SRC_FILES := libtest.so
include $(PREBUILT_SHARED_LIBRARY)
Add this module name to PRODUC_PACKAGES micro.
These so in your app will be built to your system/lib or lib64.
Good luck.
I have a custom android system image, I'd like to build my aar project(lib1.aar) into our android source code. My app app1, app2 will use this lib1.aar as their dependencies. I used below Android.mk file to make it, but I got 'R cannot be resolved to a variable' error since my code imported it like calling string from resource file.
LOCAL_PACKAGE_NAME := lib1
LOCAL_CERTIFICATE := platform
LOCAL_PROGUARD_ENABLED := disabled
include $(BUILD_JAVA_LIBRARY)
My question is how to write Android.mk file to compile my lib1.aar as a system lib to let my app use?
Thanks in advance.
You can include your .aar libs with these lines:
LOCAL_STATIC_JAVA_AAR_LIBRARIES:= <aar alias>
include $(BUILD_PACKAGE)
include $(CLEAR_VARS)
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := <aar alias>:libs/<lib file>.aar
include $(BUILD_MULTI_PREBUILT)
Please, be aware of your projects and lib's minSDKVersion.
I have added ndk plugin in Eclipse.
I have imported a NDK project in Eclipse.
But projects requires external .h file from the system, so I have added that folder where .h files files resides by
right click on project-> c/C++ General->Paths and symbols->then click on
include and then click add and given path of that folder
also checked all configurations and all languages.
still when I build the project from Command prompt by moving to path where my project is , then ndk-build I am getting for .h file no such file or directory error.
How can I resolve this issue??
Please help...
Please refer to documentation of LOCAL_C_INCLUDES variable
what you did to add the reference the external headers was only for eclipse, so it correctly resolves all the symbols and files references.
You also need to properly add a reference to these .h inside your ndk configuration files, ie inside Android.mk.
Use LOCAL_C_INCLUDES := path/to/headers in your module, like in this sample Android.mk file:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := main.c
LOCAL_MODULE := mymodule
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../includes
include $(BUILD_SHARED_LIBRARY)
If your .h files are part of a prebuilt module your own module depends on, use LOCAL_EXPORT_C_INCLUDES inside the prebuilt module instead of LOCAL_C_INCLUDES inside yours.
My question is:
I have used ndk to develop some functions, when built, it created a .so file in libs/armeabi. Now I needed to add another .so file from others. I only copied the .so to my dir libs/armeabi, then built it. The .so file was missing and I only had mine.
I do not kown why it happens. Should I need to config my Android.mk file, or any else?
This happens because the libs folder is cleaned when you run the ndk-build!
Edit your Android.mk and add this:
include $(CLEAR_VARS)
LOCAL_MODULE := MYOTHERSO-prebuilt
LOCAL_SRC_FILES := [relative path to your other .so]/lib[change to your lib name].so
LOCAL_EXPORT_C_INCLUDES := [relative path to your other .so include files]
include $(PREBUILT_SHARED_LIBRARY)
You should store the .so file on another path (not on libs/armeabi folder) in order to reference it from your Android.mk. During ndk-build it will be copied to libs/armeabi folder.
I tried to add a prebuilt APK to my Android build. The APK contains several shared libraries (*.so files). It compiles without problem, but I still get an error from the app indicating that the libraries cannot be found.
Why could this be?
Here is the android.mk code:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := apkwithso
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_REQUIRED_MODULES := libx liby libz
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)
libx, y, z are my libx.so, liby.so, and libz.so
I also tried to copy the .so manually from the APK to the out lib directories but it didn't work.
I am compiling with Android 4.1.2 for Galaxy Nexus Maguro.
I've had this problem myself, the reason is that when APK files are included in a build they are essentially bypassing the installation process. This installation process is the point at which any shared libraries are extracted from the apk and put in the appropriate place, ergo if that never happens the libraries will not be available. This is because packages that are built from source during the AOSP build either have their prebuilt shared libraries included during that build process or their libraries are also built from source, and in either case those libraries are put in the appropriate place.
For this reason in addition to the apk module itself you should add the following in the same .mk file:
include $(CLEAR_VARS)
LOCAL_MODULE := libapkwithso
LOCAL_SRC_FILES := lib/libapkwithso.so # or wherever your so is
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_SUFFIX := .so
LOCAL_MODULE_CLASS := SHARED_LIBRARIES
include $(BUILD_PREBUILT)
Then add:
LOCAL_REQUIRED_MODULES := libapkwithso
BUILD_PREBUILT calls prebuild.mk script. The description of this script is the following:
Standard rules for copying files that are prebuilt
It does not tell that the application will be installed. So I think that is why your application cannot find the libraries.
The solution is to extract libraries from the package and copy them separately from the application. The details how to do this you can find here.
Files can also be be specified in aospSource:destinationOnImage format like this in the device-partial.mk when adding a custom vendor directory:
PRODUCT_COPY_FILES += \
vendor/your-custom-vendor/your-device/proprietary/libx.so:system/lib/libx.so
You can add pretty much anything you like here (other than .apk files), and it will be copied to your image.
My Instructions is not about your error! But it may be helpful for similar error
If you try to copy prebuilt apk using:
PRODUCT_COPY_FILES += $(LOCAL_PATH)/prebuilt/filename.apk
and you getting this error:
Prebuilt apk found in PRODUCT_COPY_FILES: ... , use BUILD_PREBUILT instead!. Stop.
You can remove this check my modify the file build/core/MakeFile and comment this lines:
define check-product-copy-files
$(if $(filter %.apk, $(call word-colon, 2, $(1))),$(error \
Prebuilt apk found in PRODUCT_COPY_FILES: $(1), use BUILD_PREBUILT instead!))
endef
by inserting # before each line
Too add multiple libraries to one apk one additional section (as in answer of Justin Buser) should be added for each separate library.
