Android.mk包含預建庫

Question

我很難在Android上編譯模塊。 它引用了一個已經存在的共享庫 - 我只有.so和.h文件。

我目前的Android.mk看起來像這樣：

LOCAL_PATH:= $(call my-dir)
EXEC_ARCH := armeabi-v7a    

local_vendorlib_c_includes := $(LOCAL_PATH)/VENDORLIB/include

# VENDORLIBWrapper library
include $(CLEAR_VARS)

LOCAL_MODULE_CLASS := SHARED_LIBRARIES
LOCAL_SRC_FILES := mylib.cpp
LOCAL_MODULE:= libvendorwrapper
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_PATH := $(TARGET_OUT_SHARED_LIBRARIES)/soundfx
LOCAL_LDLIBS := -L$(LOCAL_PATH)/DPS/$(EXEC_ARCH)/
LOCAL_C_INCLUDES := \
    $(call include-path-for, graphics corecg) \
    $(call include-path-for, audio-effects) \
    $(local_dps_c_includes)

LOCAL_CPPFLAGS += -O2 -Wno-unused-parameter
#--verbose

LOCAL_SHARED_LIBRARIES := \
    libcutils \
    libdl \
    libVendorLib
#LOCAL_PREBUILT_LIBS += libVendorLib
LOCAL_REQUIRED_MODULES := libVendorLib

include $(BUILD_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE_CLASS := SHARED_LIBRARIES
LOCAL_MODULE := libVendorLib
LOCAL_SRC_FILES := $(LOCAL_PATH)/VendorLib/$(EXEC_ARCH)/libVendorLib.so
LOCAL_MODULE_TAGS := debug
LOCAL_EXPORT_C_INCLUDES := $(local_vendorlib_c_includes)
include $(PREBUILT_SHARED_LIBRARY)


include $(call all-makefiles-under,$(LOCAL_PATH))

我收到以下錯誤：

我最終通過進行以下更改來構建它

我能夠構建它進行以下更改：

include $(CLEAR_VARS)
LOCAL_MODULE_CLASS := SHARED_LIBRARIES
LOCAL_MODULE := libVendorLib
LOCAL_SRC_FILES := libVendorLib.so # <== Moved the prebuilt lib to root / -- oddly enough, when it was in a subfolder, make would not find it.
LOCAL_MODULE_TAGS := debug
LOCAL_EXPORT_C_INCLUDES := $(local_vendorlib_c_includes)
include $(BUILD_PREBUILT) # <== changed this from PREBUILT_SHARED_LIBRARY

現在我得到：
