android - 无法执行 dex : Multiple dex files define & java. lang.NoClassDefFoundError

Question

我在 2 个错误之间。我不知道该怎么办。第一个错误:

[2014-07-04 15:07:01 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/google/gdata/util/common/base/Escaper;

[2014-07-04 15:07:01 - MyGov] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/google/gdata/util/common/base/Escaper;Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;

按照建议here , 未选中的 Android 私有(private)库

我已将所有库(来自 AndroidPrivateLibraries)添加到 libs 中，除了 support-v4-18.0.4.jar 库(这会导致之前所述的错误)。

SplashActivity(此 Activity 在应用程序启动时打开)工作正常。但是当我尝试打开 MainActivity 时出现以下错误:

java.lang.NoClassDefFoundError: com.globalsolutions.mygov.ui.MainActivity

根据 this solution , 应检查 Android 私有(private)库。

结论:

error#1 makes me to uncheck Android Private libraries
error#2 makes me to re-check Android Private libraries

这种情况怎么办？如何解决这个问题呢？感谢您抽出宝贵时间!

Answer 1

I am between 2 errors. I dont know what to do. 1st error:

这个错误是不言自明的。您包括 2 个以上具有重复项的 JAR(或一个 JAR 加上您自己的 Java 类)。

解决方案是确定重复项的来源(例如，检查 JAR)，然后找出要更改或删除的 JAR。

As suggested here, unchecked Android Private Libraries

我否决了这个答案，因为它是相当错误的。

I have added all libraries(from AndroidPrivateLibraries) into libs except support-v4-18.0.4.jar library(which is causing to before stated error).

我将这句话解释为“当我添加 support-v4-18.0.4.jar 时，我开始遇到构建错误”。在这种情况下，您知道两个 JAR 之一是问题的根源。鉴于冲突的类名，我猜测另一个是 libGoogleAnalyticsV2.jar。您需要:

1. 找到这些 JAR 的设计用于协同工作的版本，或者

2. 摆脱其中一个 JAR。
