在java.util.Deque.push异常java.lang.NoSuchMethodError [英] Exception java.lang.NoSuchMethodError on java.util.Deque.push

问题描述

这真的很奇怪，谷歌开发者控制台，错误报告页。

It's really strange, Google Developer Console, error reporting page.

，因为它似乎，在多个Android设备我的应用程序崩溃。提供的异常日志说：

As it seems, my application crashes on several Android devices. The exception log provided says:

java.lang.NoSuchMethodError: java.util.Deque.push
at com.larvalabs.svgandroid.SVGParser$SVGHandler.<init>(SVGParser.java:869)
at com.larvalabs.svgandroid.SVGBuilder.build(SVGBuilder.java:147)
at myapp.graphic.PictureCache.getSvgPicture(PictureCache.java:59)
at myapp.graphic.PictureCache.getSvgPictureDrawable(PictureCache.java:65)
at myapp.activities.startup.ActivityStartup.setupCustomGraphic(ActivityStartup.java:92)
at myapp.activities.startup.ActivityStartup.onCreate(ActivityStartup.java:35)
at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1069)
...

我使用该库：

I'm using that library:

HTTP：//$c$c.google.com/p / SVG-的android-2 /

我包括源代码，而不是简单地链接外部库。

I included the source cod, not simply linked the external library.

在code似乎在 java.util.Deque.push 失败（的NoSuchMethodError ）。这不是源$ C ​​$ C，我复制并粘贴一个问题，似乎没有出列方法在运行时找到了！它是如何可能的？无法想象。

The code seems to fail on java.util.Deque.push (NoSuchMethodError). It's not a problem of the source code I've copied and pasted, it seems that no dequeue method is found on runtime! How it's possible? Can't imagine.

编辑： 双端队列的定义：

Deque<Matrix> matrixStack = new LinkedList<Matrix>();

在code是提高对这一问题：

The code that raise the problem:

matrixStack.push(new Matrix());

难道新的Matrix（）返回一个不接受推（）方法的价值？

Is it possible that new Matrix() returns a value that is not accepted by the push() method?

推荐答案

您的项目引用 java.util.Deque 这是只有在API层面增加9

Your project references java.util.Deque which was only added in API level 9

（ http://developer.android.com/reference/java/util /Deque.html ）

使用API​​级别和LT装置; 9将失败，因为他们不能调用这个类/方法，因为它并没有对他们的存在。

Devices with API level < 9 will fail as they cannot call this Class/method as it doesn't exist on them.
