我一直在纺纱一罐的Andr​​oid库项目，包括这个jar在我的其他应用程序。但是，上developer.android.com ，我看到这样的说法，我可以T分发库在一个罐子里：

I've been spinning a jar for android library project and including this jar in my other apps. But on developer.android.com, I see this statement that I can't distribute a library in a jar:

一个库无法散发为二进制文件（如JAR文件）。   这将在SDK工具的未来版本中加入。

A library cannot be distributed as a binary file (such as a JAR file). This will be added in a future version of the SDK Tools.

我真不明白是什么意思。

I really don't understand what does that mean.

推荐答案

它可以创建一个Android库项目，不 包括源$ C ​​$ C。局限性是：

It is possible to create an Android library project that does not include source code. The limitations are:

您还是要出货的资源。

You still have to ship the resources.

您必须重写你的code，以避免使用R.值，因为它们 将是错误的。你将不得不使用查找所有的资源标识 getResources（）。则getIdentifier（）和/或反射。

You have to rewrite your code to avoid using R. values, as they will be wrong. You will have to look up all resource IDs using getResources().getIdentifier() and/or reflection.

我要高级的Andr​​oid的的忙碌codeR说明书中的说明 发展的（ http://commonsware.com/AdvAndroid ），虽然 说明新的不够，没有我的免费版本有他们。 引用一些指令从当前版本：

I have the instructions in The Busy Coder's Guide to Advanced Android Development (http://commonsware.com/AdvAndroid), though the instructions are new enough that none of my free versions have them. Quoting some of the instructions from the current edition:

您可以通过以下步骤创建一个二进制只有库项目：

"You can create a binary-only library project via the following steps:

创建一个Android库项目，与源$ C ​​$ c和这样的 - 这是你的主项目，从中你将创建一个版本 库项目的分布情况。

Create an Android library project, with your source code and such – this is your master project, from which you will create a version of the library project for distribution.

编译Java源代码（例如，蚂蚁编译），并把它变成一个JAR文件

Compile the Java source (e.g., ant compile) and turn it into a JAR file

由此产生的分配的Andr​​oid库项目将拥有一切一 主体工程需要，只是没有源$ C ​​$ C。

The resulting distribution Android library project will have everything a main project will need, just without the source code."

就个人而言，我只是稍等一下。我希望官方 支持库项目-AS-JAR文件将提供soonish。

Personally, I'd just wait a bit. I am hopeful that the official support for library-projects-as-JARs will be available soonish.
