Question

我用android ndk编译了一个本机代码。现在，而不是保持该库作为.apk的一部分，我想安装在Android系统（系统/ lib64）和我的应用程序从系统加载。我将库推送到system / lib64并从android应用程序的lib文件夹中删除了库。但是当我试图跑步时我正在

"java.lang.UnsatisfiedLinkError: dlopen failed: library "something.so" not found"

以下是我的makefile

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := eng
LOCAL_C_INCLUDES += $(LOCAL_PATH) $(LOCAL_PATH)/Include
LOCAL_SRC_FILES := ABCProtocol/ABCProtocol.c ABCProtocol/DatalinkLayer.c ABCProtocol/PhysicalLayer.c
LOCAL_MODULE := libABCXYZProtocol
include $(BUILD_SHARED_LIBRARY)

include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := eng
LOCAL_C_INCLUDES += $(LOCAL_PATH) $(LOCAL_PATH)/$(KERNEL_DIR)/include $(LOCAL_PATH)/Include $(LOCAL_PATH)/Util $(LOCAL_PATH)/Include/Linux/XYZ $(LOCAL_PATH)/ABCProtocol
LOCAL_SRC_FILES := Linux/XYZ/ABCXYZLinux.c Util/Util.c Util/Logger.c
#LOCAL_CFLAGS += -Wno-error=format-security
LOCAL_CFLAGS += -w
LOCAL_MODULE := libABCXYZWrapper
LOCAL_SHARED_LIBRARIES :=libABCXYZProtocol
include $(BUILD_SHARED_LIBRARY)

include $(CLEAR_VARS) 
LOCAL_MODULE_TAGS := eng
LOCAL_MODULE:=com_example_reader_ABCXYZappnote_NativeLibrary
LOCAL_SRC_FILES:=com_example_reader_ABCXYZappnote_NativeLibrary.c
LOCAL_C_INCLUDES += $(LOCAL_PATH) $(LOCAL_PATH)/$(KERNEL_DIR)/include $(LOCAL_PATH)/Include $(LOCAL_PATH)/Util $(LOCAL_PATH)/Include/Linux/XYZ
#LOCAL_CFLAGS += -DANDROID
LOCAL_SHARED_LIBRARIES:=libc libABCXYZWrapper libABCXYZProtocol
include $(BUILD_SHARED_LIBRARY)

不允许应用程序从系统库位置访问非公共API：https://developer.android.com/about/versions/nougat/android-7.0-changes.html#ndk。您的应用使用的库必须与您的应用一起打包。

为什么要将它们放在/ system / lib中？

将本机库从Android应用程序移动到系统lib并从应用程序
