在包含资源的库项目上构建错误

我试图在系统构建环境中构建项目。该项目包含一个包含一些资源的图书馆项目。库项目中的代码访问这些资源。建筑失败了一些错误。以下是详细信息：

项目的结构是：

packages/experimental/MyApplication/
  |--AndroidManifest.xml
  |--Android.mk
  |--proguard.flags
  |--libs/
  |--res/
  |--src/
  |--mylibrary/
  |    |--AndroidManifest.xml
  |    |--Android.mk
  |    |--libs/
  |    |--res/
  |    |    |--values/strings.xml
  |    |--src/
  |    |--  |--com/example/mytest/CustomView.java

mylibrary是图书馆项目。在其中，有一个CustomView.java访问strings.xml中定义的字符串资源。主项目的makefile是：

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
mylib_dir := mylibrary/res
res_dir := $(mylib_dir) res

LOCAL_MODULE_TAGS := optional

LOCAL_SRC_FILES := $(call all-java-files-under, src)
LOCAL_RESOURCE_DIR := $(addprefix $(LOCAL_PATH)/, $(res_dir))
LOCAL_AAPT_FLAGS := --auto-add-overlay
LOCAL_AAPT_FLAGS += --extra-packages com.example.popoalex.mylibrary

LOCAL_STATIC_JAVA_LIBRARIES := mylibrary okhttp

LOCAL_PACKAGE_NAME := MyApplication
#LOCAL_CERTIFICATE := platform
#LOCAL_PROGUARD_FLAG_FILES := proguard.flags

include $(BUILD_PACKAGE)
##################################################
include $(CLEAR_VARS)

LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := okhttp:libs/okhttp-1.0.0.jar

include $(BUILD_MULTI_PREBUILT)

# only include rules to build other stuff for the original package, not the derived package.
ifeq ($(strip $(LOCAL_PACKAGE_OVERRIDES)),)
# Use the folloing include to make our test apk.
include $(call all-makefiles-under,$(LOCAL_PATH))
endif

库项目的makefile是：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := mylibrary
LOCAL_STATIC_JAVA_LIBRARIES := gson
LOCAL_SRC_FILES := $(call all-java-files-under, src)
LOCAL_RESOURCE_DIR := $(LOCAL_PATH)/res
include $(BUILD_STATIC_JAVA_LIBRARY)

##################################################

include $(CLEAR_VARS)
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := gson:libs/gson-2.2.4.jar
include $(BUILD_MULTI_PREBUILT)

##################################################
# Build all sub-directories

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

我使用的构建命令是：

mmm packages/experimental/MyApplication/

建筑物输出是：

如果我注释掉访问字符串资源的代码，则构建成功。我只使用默认的proguard.flags。我运行该系统的系统是Ubuntu 14.04，源代码基于CM 10.2（与AOSP 4.3.1等效）。

更新

成功生成了库项目构建的中间文件。在目录中：out / target / common / obj / JAVA_LIBRARIES / mylibrary_intermediates /

1 个答案:

答案 0 :(得分：0)

我终于解决了这个问题。构建脚本没问题，只是因为上次生成的中间文件不正确。删除文件夹“out / target / common / obj / APPS / MyApplication_intermediates /”并再次运行建筑物后，它就成功了。

顺便说一句，对于库包含和使用资源。建筑的关键是“LOCAL_AAPT_FLAGS：= --extra-packages”，它可以结合库jar和amp;主要项目的资源。
