Android.mk 包含预建库

Question

我正在努力获取一个模块以在 Android 上编译。它引用了一个已经存在的共享库——我只有 .so 和 .h 文件。

我当前的 Android.mk 如下所示:

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))

我收到以下错误:

我终于能够通过进行以下更改来构建它

我能够通过以下更改构建它:

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

现在我得到:

make completed successfully (21 seconds)
