Question

刚开始，我并不是想从Android中的.xlsx文件中读取单元格，我已经尝试了几乎所有我用Google搜索的东西，但每次（在两台不同的PC上，都是Java 1.7.0_79）当我试图构建（运行）这个应用程序时，它都以相同的错误结束：

Error:Execution failed for task ':app:dexDebug'.
> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_79\bin\java.exe'' finished with non-zero exit value 1

我不知道，我还应该做些什么，Java和Android Studio已经重新安装......没什么。我使用了来自https://github.com/hmkcode/Java/tree/master/java-excel-poi

的代码

trouble processing "javax/xml/stream/events/StartElement.class":
Ill-advised or mistaken usage of a core class (java.* or javax.*)
when not building a core library.
This is often due to inadvertently including a core library file
in your application's project, when using an IDE (such as
Eclipse). If you are sure you're not intentionally defining a
core class, then this is the most likely explanation of what's
going on.
However, you might actually be trying to define a class in a core
namespace, the source of which you may have taken, for example,
from a non-Android virtual machine project. This will most
assuredly not work. At a minimum, it jeopardizes the
compatibility of your app with future versions of the platform.
It is also often of questionable legality.
If you really intend to build a core library -- which is only
appropriate as part of creating a full virtual machine
distribution, as opposed to compiling an application -- then use
the "--core-library" option to suppress this error message.
If you go ahead and use "--core-library" but are in fact
building an application, then be forewarned that your application
will still fail to build or run, at some point. Please be
prepared for angry customers who find, for example, that your
application ceases to function once they upgrade their operating
system. You will be to blame for this problem.
If you are legitimately using some code that happens to be in a
core package, then the easiest safe alternative you have is to
repackage that code. That is, move the classes in question into
your own package namespace. This means that they will never be in
conflict with core system classes. JarJar is a tool that may help
you in this endeavor. If you find that you cannot do this, then
that is an indication that the path you are on will ultimately
lead to pain, suffering, grief, and lamentation.

库

我有什么解决方案吗？

Answer 1

原因是至少有一个库（xmlbeans.jar）声明可能与Android使用的核心库冲突的类。

xmlbeans在javax.xml包中声明了类 - Android也有this package中的类和其他类似的类。

从错误消息：

如果您合法地使用恰好位于核心中的某些代码包装，那么最简单的安全替代方案就是重新包装那段代码。 也就是说，将有问题的课程移到您自己的课程中包命名空间。

基本上，构建工具认为您应该构建核心库，而是尝试使用与默认Android核心库冲突的库来构建应用程序。它建议您将您的代码从核心包移到另一个包中。

我的建议 - 停止使用尝试使用核心软件包名称的外部库并使用Android提供的XML功能。

Answer 2

遗憾的是，由于引入了第三方库依赖关系，您无法在Android上直接使用Apache POI。此外，库的大小会导致非常大的应用程序文件，这通常是不可能/不可取的。您甚至有时会超过Dalvik Android Bytecode编译所施加的限制。

有一些资源可以讨论如何在Android上运行POI：

Answer 3

我有一个想法，你可以遵循：你导入的一些jar是内部API，比如layoutlibs.jar，它们只涉及编译，而不是打包在apk中。如果你想使用它们，只需在模块的根目录下创建一个名为mylib的文件夹，然后查看图片，跟着他们：

如果我的答案解决了您的问题，请采纳它。

Answer 4

问题：java.exe以非零退出值1

结束

解决方案：为了解决这个问题，我尝试了大多数解决方案，然后一次又一次地尝试。

最后找到了解决这个问题的方法。

这些是您应该尝试解决问题的可能解决方案，据我所知，它肯定会解决您的问题。

清理并重建您的项目。
请检查所有库是否已更新，并且gradle build版本也已更新。
尝试增加您的Java堆大小。
不要在代码中使用lambda表达式或语法。在我的情况下，这是问题，因为我使用lambda表达式，当我使用lambda表达式时，它需要在build.gradle（app）文件中声明，如

compileOptions { targetCompatibility 1.8 sourceCompatibility 1.8 }

此。

这是我遇到的实际问题，请从build.gradle文件中删除此compileOptions声明，或使用与Gradle版本兼容的正确版本。

我希望这个解决方案能够帮助您解决问题。
