拋出java.lang.ClassNotFoundException在dalvik.system.BaseDexClassLoader.findClass

這個錯誤讓我發瘋了。拋出java.lang.ClassNotFoundException在dalvik.system.BaseDexClassLoader.findClass

java.lang.ClassNotFoundException 
in dalvik.system.BaseDexClassLoader.findClass

我的應用程序不會生成當從日食在我們的兩個設備崩潰：當下載從谷歌Play商店與錯誤我的應用程序在啓動時崩潰。然而，一個月前，一位客戶使用他的手機來開發我們的應用程序，然後它在啓動時也崩潰了。我忽略了這個問題，因爲它在我們的設備上工作，並認爲它與Google Map鍵或Keystore有關。

現在事實證明，我們的每一個設備上的應用程序崩潰從Play商店下載的時候。我明白，解決這個問題並不是一個簡單的方法，但我們希望能夠朝着正確的方向前進。

我也覺得很難調試這個問題，因爲應用程序的偉大工程時，構建從我們的設備日食！

這裏是我報告的完整的錯誤日誌：

是否使用ProGuard構建？我想知道ProGuard是否因爲認爲它未被使用而將代碼剝離出來。 – fadden

如果這個類確實存在（沒有被排除），那麼dalvik可能因爲某種原因拒絕了這個類。如果是這種情況，當您安裝應用程序時，您會看到來自dalvik的一些錯誤消息。 – JesusFreke

我在安裝我的應用程序時添加了日誌。現在就看看ProGuard。 –

因此，確實ProGuard正在從我的項目中剝離代碼。我用ActionBarSherlock和Facebook這是我添加什麼，所以這是可行的：

# ActionBarSherlock 

-keep class android.support.** { *; } 

-keep interface android.support.** { *; } 

-keep class com.actionbarsherlock.** { *; } 

-keep interface com.actionbarsherlock.** { *; } 




# Keep line numbers to alleviate debugging stack traces 

-renamesourcefileattribute SourceFile 

-keepattributes SourceFile,LineNumberTable

這對於Facebook：

-keepclassmembers class * implements java.io.Serializable 
{ 
    private static final java.io.ObjectStreamField[] serialPersistentFields; 
    private void writeObject(java.io.ObjectOutputStream); 
    private void readObject(java.io.ObjectInputStream); 
    java.lang.Object writeReplace(); 
    java.lang.Object readResolve(); 
}

那麼，我建議你關注一下你在eclipse上製作的版本和你提供給Play商店的版本之間的區別。

如果你能重現您從Play商店中看到，而用eclipse建立並測試它的錯誤，你一定會找到答案。

我能想到的是，應用程序被簽署的證書，但它似乎沒有吧。但是，您應該更多地考慮兩個.apk的區別 - 開發人員構建和playstore的構建。

由於apk文件基本上都是存檔，可以解壓他們兩個，看他們之間的差異。您應該使用dedexer來嘗試反編譯classes.dex的兩個實例（請參閱decompiling DEX into Java sourcecode）。它可能是高度混淆的代碼，但你應該尋找丟失的類或類似的東西。

希望你得到它的權利。

感謝您的這個提示！當我回家的時候，我會很開心的。 –

右鍵單擊您的項目文件夾=>屬性=> Java構建路徑=>訂單和導出=>如果未選中，請選中「Android專用庫」框。它的工作原理！
