java - Android 项目中的 ClassNotFoundException 仅在我的 PC 上

标签 java android kotlin noclassdeffounderror classnotfoundexception

最近，当我打算在家中使用装有 Windows 8.1 的 PC 完成我的工作时，我发现该项目无法正常运行 - 它编译，在模拟器上运行并在某个特定点崩溃(它是在我的 PC 上 100% 可重现)。

但是，相同的存储库修订版适用于工作中的 Mac 和我同事的 Windows 10 计算机。

每个提到的环境都使用 Android Studio 2.3.1、gradle 3.3 和 Kotlin 1.1.1，并在 API 25 x86_64 图像上运行应用程序。

该项目正在使用 multidex 1.0.1 库。

崩溃是由于以下异常导致的:

BaseActivity.kt

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

SomeActivity.kt - 崩溃

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 - 使用与 SomeActivity 相同的功能并且不会崩溃

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
            }
        }
    }
}

所有这些代码都在项目中存在了一两个多月，两周前它在我的电脑上运行。

我已经尝试过的:

  • ./gradlew cleanBuildCache

  • 删除$HOME/.gradle/caches

  • 删除$HOME/.android/build-cache

  • 删除$HOME/.AndroidStudio2.3/system/caches

  • 删除了 build 和 app/build 目录

  • 删除项目根目录下的.gradle目录

  • Android Studio 使缓存失效并重启

  • 从模拟器中手动卸载应用程序并重新安装

  • 重新安装 Android Studio 2.3.1

  • 将 Android Studio 降级到 2.3(这是我 2 周前使用的版本，我知道它当时可以用)

知道这里出了什么问题吗？

最佳答案

几周前我遇到了类似的问题。这基本上是我为避免 ClassNotFoundException 所做的，在我的例子中是由于更新 Android Studio、gradle 等后的 Multidex“配置”。

  1. 将 compile 'com.android.support:multidex:1.0.1' 添加到应用程序 gradle 文件中的依赖项列表中。

  2. 从 Application 类的 onCreate() 方法中删除 Multidex.install(this); 并在您的 Application 类中添加以下内容:

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

我在更新 gradle 版本等后收到错误，因此请确保您也已更新所有内容。

希望对您有所帮助。
