Android項目中的ClassNotFoundException僅在我的PC上

最近，當我在家用我的電腦用Windows 8.1完成我的工作時，發現項目無法正常工作 - 編譯，在仿真器上運行並在某些特定點崩潰（它可以在我的PC上100％重現）。Android項目中的ClassNotFoundException僅在我的PC上

但是，同一個存儲庫版本可以在Mac上工作，也可以在同事的Windows 10機器上工作。

每個提到的環境都使用Android Studio 2.3.1，gradle 3.3和Kotlin 1.1.1，並在API 25 x86_64映像上運行應用程序。

該項目使用multidex 1.0.1庫。

的崩潰發生是由於以下異常：

BaseActivity.kt

abstract class BaseActivity : RxAppCompatActivity(), HasErrorHandler (...)

SomeActivity.kt - 這種崩潰

class SomeActivity : BaseActivity(), HasFullWindowProgress (...) { 

    (...) 

    private fun getDataFor(id: String) { 

     apiClient.somethingList(id) 
       .map { response -> response.toSomethingList() } 
       .lifecycle(this) 
       .showProgress(this) 
       .observeOnMainThread() // <== line 164 
       .subscribe({ 
        LOG.info("Something list fetched ${it.size}") 
        adapter.setItems(it) 

       }, defaultOnError("Fetching something list failed")) 
    } 
}

AnotherActivity.kt - 使用相同的功能，SomeActivity和不會崩潰

class AnotherActivity : BaseActivity(), HasFullWindowProgress (...) { 

    (...) 

    private fun getData() { 
     somethingElse.user?.id?.let { id -> 

      apiClient.somethingElseList() 
        .map { response -> response.toAnotherList(id) } 
        .lifecycle(this) 
        .showProgress(this) 
        .observeOnMainThread() 
        .subscribe({ 
         onNewSomethingElseList(id, it) 
        }, defaultOnError("Fetching somethingElseList for somethingElse failed")) 
     } 

    } 
}

ActivityErrorHandlingExtensions.kt

fun <T> T.defaultOnError(message: String, vararg args: Any?): (Throwable) -> Unit where T : HasErrorHandler, T : Activity { 
    val targetClass = javaClass 
    val activity = this 
    return { err -> 
     val messageFormats = (args.toList() + err).toTypedArray() 
     LoggerFactory.getLogger(targetClass).error(message, *messageFormats) 
     errorHandler.default(err, activity) 
    } 
}

ObservableExtensions.kt

fun <T> Observable<T>.lifecycle(activity: RxAppCompatActivity) : Observable<T> { 
    return compose(activity.bindToLifecycle<T>()) 
} 

fun <T> Observable<T>.observeOnMainThread() : Observable<T> { 
    return observeOn(AndroidSchedulers.mainThread()) 
}

Progress.kt

fun <T> Observable<T>.showProgress(hasProgress: HasFullWindowProgress): Observable<T> { 
    return compose { 
     it.doOnSubscribe { 
      MAIN_THREAD_WORKER.schedule { 
       hasProgress.fullWindowProgress.visibility = View.VISIBLE 
      } 
     }.doAfterTerminate { 
      MAIN_THREAD_WORKER.schedule { 
       hasProgress.fullWindowProgress.visibility = View.GONE 
      } 
     } 
    } 
}

所有這些代碼是在項目上一兩個月，並在兩個星期前，我的工作電腦上。

我已經嘗試過：

./gradlew cleanBuildCache
刪除$HOME/.gradle/caches
刪除$HOME/.android/build-cache
刪除$HOME/.AndroidStudio2.3/system/caches
刪除build和app/build迪爾斯
在項目的根目錄中刪除.gradle DIR
Android Studio中無效的緩存和重新啓動
手動卸載從模擬器的應用程序，並重新安裝它
重新安裝Android Studio 2.3.1
降級的Android工作室到2.3（這是我用了2個星期前的版本，我知道那麼它的工作）

任何想法有什麼不對嗎？該getDataFor方法

您可以發佈「工具 - > Kotlin - >顯示Kotlin字節碼」的問題活動的輸出嗎？ –

@VyacheslavGerasimov請參閱更新。我發佈了'getDataFor'字節碼。讓我知道如果你需要更多，因爲我不想花費全天混淆所有2.5k行字節代碼:) –

是否有字節碼中的任何類名稱爲com/project/package/SomeActivityKt $ sam $ Action1 $ 22181393' ？我想它應該爲您傳遞給訂閱方法的lambda生成。我的理論，它可能會產生一個錯誤的名稱。 –

我幾個星期前，碰到了類似的問題。這基本上是我做過什麼，以避免ClassNotFoundException，在我的情況是由於Multidex「配置」更新Android工作室，gradle產出等

添加compile 'com.android.support:multidex:1.0.1'到依賴項列表中的應用程序文件的gradle後。

從您的應用程序類的onCreate()方法刪除Multidex.install(this);並添加應用程序類以下內容：

@Override 
protected void attachBaseContext(Context context) { 
    super.attachBaseContext(context); 
    MultiDex.install(this); 
}

我更新版本的Gradle，等以後得到了錯誤，所以請確保您所有的東西都是最新的。

希望它有幫助。

我不會在'onCreate（）'中調用'Multidex.install（this）'，因爲我的'App'類從'MultiDexApplication'類繼承了這個行爲（'attachBaseContext'已經在那裏實施）。所以我只添加了覆蓋（可能是多餘的）。不幸的是，它根本沒有幫助。它仍然在'SomeActivity'中崩潰（這不是在我的應用程序中啓動的第一個，順便說一句）。 –

Android項目中的ClassNotFoundException僅在我的PC上
