Android的图书​​馆项目已编译的JAR库 [英] Android Library Project as compiled JAR library

问题描述

我创建一个自定义视图的API。为了使视图有在XML自定义属性我想用Android的图书​​馆项目的API。通过这一点，我可以宣布我的自定义的定义在attrs.xml属性。

I am creating an API with a custom view. In order to enable the view to have custom attributes in the XML I want to use the "Android Library Project" for the API. By this I can declare the definition of my custom attributes in an attrs.xml.

但我有问题，将其导出到一个JAR文件时所使用的图书馆项目。该项目引用JAR得到与包括在JAR android的资源文件的问题。有谁知道如何做到这一点？希望我已经清楚我的问题。
我不能让这个项目在这种情况下，一个开源项目。

But I'm having problems to use the Library Project when exporting it to an JAR-file. The project referencing the JAR gets problems with the android resource files included in the JAR. Does anyone know how to accomplish this? Hope I've been clear in my question. I cannot let the project be an open source project in this case.

你不能将库项目导出到一个JAR文件
库不能分发为二进制文件（如一个jar文件）。这是因为库项目由主体工程使用正确的资源ID编。

"You cannot export a library project to a JAR file A library cannot be distributed as a binary file (such as a jar file). This is because the library project is compiled by the main project to use the correct resource IDs."

所以我想那种回答我的问题。我已经尝试了一半的工作方案。这是生成Java源文件的JAR和只添加了Android XML资源，attrs.xml到谁使用JAR每个项目。但它不是我想要实现的东西一个很好的解决方案。我想与源和XML资源，JAR，但还没有找到一个解决方案这一点。

So I guess that kind of answers my question. I've tried a half working solution. It is to generate a JAR from the java source files and add only the Android xml resources, as attrs.xml to each project who use the JAR. But it is not a good solution for the thing I want to achieve. I want a JAR with both source and xml resources but haven't found a solution for this.

推荐答案

从的 code.google.com发行9656：库项目不支持自定义CLASSE 的自定义XML属性，...如果你有这些工具R17

an update from code.google.com Issue 9656: Library projects don't support custom XML attributes for custom classe, … if you have r17 of the tools.

专门从该链接的文本：

看一看到什么是在SDK R17新的

Take a look into "what's new in sdk r17":

增加了对库中的自定义属性自定义视图支持。
  使用自定义属性的布局必须使用命名空间URI
   http://schemas.android.com/apk/res-auto 而不是URI那
  包括应用程序包名称。这个URI替换为应用程序
  特定的一个在构建时。

Added support for custom views with custom attributes in libraries. Layouts using custom attributes must use the namespace URI http://schemas.android.com/apk/res-auto instead of the URI that includes the app package name. This URI is replaced with the app specific one at build time.

今天工作对我来说就像一个魅力！我现在有一个包含我的自定义窗口小部件，所以我可以在我的所有项目通过参考使用它的库。

worked for me like a charm today! i now have a library that contains my custom widget so i can use it in all my projects via reference.
