我进一步调查了该问题，并找到了此链接.我尝试应用以上链接中给出的补丁，但无法成功应用.

I further investigated the the issue and I found this link.I have tried to apply patch given in above link but I could not apply it successfully.

曾经在Android中使用Freemarker的人可以帮忙吗?

Can someone having used Freemarker in Android please help?

推荐答案

问题:

尽管Freemarker正式不支持Android，但它为GAE发布了特殊的* .jars，以提供一些支持，许多其他Android解决方案也可以在其应用程序中成功使用Freemarker(呈现视图/代码，或者只是评估某些视图.表达式).

Although Freemarker officially does not support Android, it published special *.jars for GAE to provide some support, and a lot of other Android solutions could successfully use Freemarker in their application (either rendering view/code, or just to evaluate some expressions).

原因:

此问题的根本原因是Freemarker将使用java.beans软件包中的一些内容，由于某些原因，这些内容未包含在Android核心库中.

The root cause of the issue is that Freemarker would use a few things from java.beans package which is for some reason not included in Android core libraries.

根据对Stackoverflow的回复(/questions/15065545/using-jars-that-use-java-beans-classes-introspector-beaninfo-or-propertydescri )，这是Android，为了完成任务，我们应该从源代码中分出所有第3方jar并重写它们，以使它们不使用java.beans.*类(可以通过将其替换为openbeans)."

According to a reply on Stackoverflow (/questions/15065545/using-jars-that-use-java-beans-classes-introspector-beaninfo-or-propertydescri), this is a disadvantage of Android, and to accomplish the task, we should "fork all 3th party jars from source and rewrite them so they don't use java.beans.* classes (possibly by replacing them for openbeans)."

解决方案:

找到可以替换的java.beans替代品，因此它可以在Android上使用.例如，可以是openbeans或mad-robot.

Find a substitution for java.beans, which can be changed, so it would work on Android. It can be openbeans, or mad-robot for example.

即使存在Freemarker的补丁程序，该补丁程序实际上也在其源代码中将java.beans更改为mad-robot bean-您可以找到该补丁程序和相关的线程此处.

Even there is a patch existing for Freemarker, which is basically changing java.beans to mad-robot beans in its source code - you can find the patch and the related thread here.

可能的解决方法:

• 为Freemarker Android支持应用补丁
• 使用openbeans.jar手动重新编译:code.google.com/p/openbeans/
• 使用mad-robot bean手动重新编译:code.google.com/p/mad-robot/

• Applying the patch for Freemarker Android support
• Manually recompiling with openbeans.jar: code.google.com/p/openbeans/
• Manually recompiling with mad-robot beans: code.google.com/p/mad-robot/
