在 Android.mk 中添加库路径 - google-play-services_lib

Question

我将 google-play-services_lib 库用于我的一个项目。一切都在eclipse中构建得很漂亮。现在我想编写一个 Android.mk 文件来自动构建我的项目。

按照指令 here ，我已将 LOCAL_LDLIBS 添加到 Android.mk，将 google-play-services_lib 库项目放入我项目的 libs 文件夹，但它不起作用。

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_SRC_FILES := $(call all-java-files-under, src)

LOCAL_PACKAGE_NAME := GoogleReviews

LOCAL_LDLIBS := -L/libs/google-play-services_lib

include $(BUILD_PACKAGE)

include $(CLEAR_VARS)

include $(BUILD_MULTI_PREBUILT)

由于我在编译过程中遇到异常，因此无法从 Android.mk 中正确检测到该库，这些异常指的是 google-play-services_lib 库中缺少的这些类。

需要做什么，这样我才能摆脱这个错误。

非常感谢任何帮助。

Answer 1

试试这个：

LOCAL_STATIC_JAVA_LIBRARIES := libgoogleplay

LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := libgoogleplay:你的谷歌播放库

Answer 2

我通过 VisualGDB 使用 NDK。

我似乎让它工作的方式是添加到project.properties 文件中。

我按照 Google 的 Android 文档似乎对 Google Play 服务的建议进行了操作，并将其从 SDK 的位置复制到了不同的位置（但不是我的项目目录）。当时位于{android-sdk}\extras\google\google_play_services\libproject

我手动编辑了project.properties 文件，并在我创建的目录中添加了一个相对路径（绝对路径不起作用）。

android.library.reference.1=<relative/path/to/my/google-play-services_lib>

（.1 是我第一次引用外部库）

然后我在此处按照 SettingUpLibraryProject 说明进行操作：http://developer.android.com/tools/projects/projects-cmdline.html#SettingUpLibraryProject

这最终创建了构建过程所需的一堆文件。之后一切都很好。
