的VerifyError - 验证拒绝类 [英] VerifyError - Verifier rejected class

问题描述

我正在开发2.2（的minSdkVersion = 8 ），并突然向我这个错误：

I'm developing for 2.2 (minSdkVersion=8) and suddenly I'm getting this error:

arbitrarily rejecting large method (regs=75 count=28584)
rejected Lcom/Demo/Loyalty/SelectType;.onClick (Landroid/view/View;)V
Verifier rejected class Lcom/Demo/Loyalty/SelectType;
Class init failed in newInstance call (Lcom/Demo/Loyalty/SelectType;)


java.lang.VerifyError: com.Demo.Loyalty.SelectType

这是工作细到现在。

It was working fine until now.

注意：选择类型类有16000左右code线，但不是大型我猜

Note : SelectType class has around 16000 lines of code but that is not that large I guess.

我搜索了很多净和答案，我当时以下内容：

I search a lot on net and from answers, I did following:

• 清洁项目


• 重置ADB


• 重新启动模拟器/设备/月食


• 经过第三方库字段在构建路径检查

但我仍然收到这个错误。

But I'm still getting that error.

任何帮助AP preciated。

Any help appreciated.

推荐答案

您可能已经说明不会帮助的步骤。

The steps you've described probably won't help.

问题是，这不是一个问题，Dalvik的。类似的验证采用了Oracle Java虚拟机为例。答案很简单：你的方法太复杂的。您所看到的错误主要是由于过多的：

The thing is, it's not a Dalvik issue. Similar verifier is employed in the Oracle Java VM for example. Simple answer: your method is too complex. The error you see is mainly caused by too many:

• 参数


• 局部变量


• 异常处理


• code说明

更多precisely，这个问题已经在此线程描述：的https://groups.google.com/forum/?fromgroups=#!topic/android-developers/4qNoIdBHYFc

More precisely, the issue has been described in this thread: https://groups.google.com/forum/?fromgroups=#!topic/android-developers/4qNoIdBHYFc

要报价：

的值（寄存器个数*的指令字数）
  大于2 ^ 21。 （......）
  它的目的是
  prevent从胃胀了一个应用程序的本地堆验证。

The value of (number of registers * number of instruction words) is larger than 2^21. (...) it's intended to prevent the verifier from bloating up an app's native heap.

You can also see similar report here: http://www.mentby.com/Group/android-developers/verifyerror-arbitrarily-rejecting-large-method.html with pointers on how to resolve the issue:

是的，在Dalvik编译器试图分配一个注册到每一个
  在该方法的局部变量。它应该能够处理许多，
  但显然不能。通过使它们的实例变量删除
  编译器的需求/欲望管理他们（也使该方法
  相当数量较小）。

Yep, the Dalvik compiler attempts to assign a "register" to every local variable in the method. It should be able to handle that many, but apparently can't. By making them instance variables you remove the compiler's need/desire to "manage" them (and also make the method a fair amount smaller).

所以要解决它，你应该打破一般大的方法（可能是的onClick（）？）成小块。此外，转换局部变量类字段似乎帮助一些人有同样的问题。

So to solve it, you should generally break the large method (probably onClick()?) into smaller pieces. Also, converting local variables to class fields seemed to help some people with the same issue.
