我有一个共享库（例如 libcrypto.so），但没有头文件。
我可以在其他模块中使用这个库吗？
我尝试使用 LOCAL_EXPORT_C_INCLUDES 导出头文件，但它不起作用。
这是预建模块：
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)
而且，这是使用 libcrypto 的模块：
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)
这是 libcrypto 模块（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)
编辑：添加了boringssl 模块。我实际上#include "openssl/crypto.h"在 test.c 中使用过
