嘗試了一切 - 轉換爲Dalvik格式失敗，出現錯誤1

Question

從我所讀到的情況來看，這個錯誤可能是由diff文件中存在的類的重複引用引起的，在我使用構建路徑擺弄後似乎是這種情況。但是，我所擁有的只是android.jar和android-support-v4.jar，在我的Build路徑和Referenced庫下，我需要獲得一個乾淨的版本。

我清理了項目，刪除了R.java，關閉並重新打開了項目，但我仍然得到了這個權利。我還能做些什麼來解決這個問題？我需要兩個.jar文件，它們是我的項目中包含的唯一文件。

trouble processing "javax/security/auth/callback/PasswordCallback.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.

我有同樣的問題，而試圖運行Android的下4. Android 3.0的寫了一個示例應用程序我註釋掉的每一個方法的主體，各個階級，並試圖刪除類路徑中的android.jar，我不再收到錯誤消息。甚至當我評論以前的代碼時，它也能正常工作......奇怪:(不幸的是，我不確定這是否是正確的解決方案，因爲我在嘗試運行應用程序時遇到了NPE，那麼你呢？ ？

Answer 2

我面臨同樣的問題，我意識到我已經添加了兩次Android庫，也是JRE環境。只要確保項目的Java構建路徑僅包含一個Android平臺作爲庫，而不是JRE，這應該可以解決這個問題

Answer 3

移除你可能在android庫中使用的任何其他庫或jar文件你可能會使用Android庫，並且已經從「Add Jar「選項，如果是這樣，請刪除附加的jar，之後，一個乾淨的版本應該可以解決你的問題問題。
