android - NoClassDefFoundError : rx. subscriptions.CompositeSubscription

Question

我有一个 Android 项目，我在其中使用了 rxjava 和 rxAndroid。我突然开始遇到崩溃 "NoClassDefFoundError: rx.subscriptions.CompositeSubscription"

网上查了下，没找到解决办法

我并没有真正改变类中的任何东西，这是抛出异常，这让我很困惑。

在我的 build.gradle 中，我编译了 'io.reactivex:rxandroid:1.2.1' 编译'io.reactivex:rxjava:1.1.6'

在我的 observable 中，我使用 okHttp 发送 http 请求，抛出异常的确切行是

subscribeOn(Schedulers.newThread()).observeOn(AndroidSchedulers.mainThread());

我需要任何建议^^，如果您有任何问题，请告诉我。

此外，如果可能的话，任何人都可以解释一下崩溃的含义吗？谢谢。

编辑我的 build.gradle 有那些

    compile 'io.reactivex:rxandroid:1.2.1'
// Because RxAndroid releases are few and far between, it is recommended you also
// explicitly depend on RxJava's latest version for bug fixes and new features.
    compile 'io.reactivex:rxjava:1.1.6'
    compile 'com.jakewharton.rxbinding:rxbinding-support-v4:0.4.0'
    compile 'com.trello:rxlifecycle:0.6.1'
// If you want pre-written Activities and Fragments you can subclass as providers
    compile 'com.trello:rxlifecycle-components:0.6.1'

    compile 'com.mlsdev.rximagepicker:library:1.1.9'
    compile 'com.github.zellius:rxlocationmanager:0.1.1'
    compile 'com.sdoward:rxgooglemaps:1.0@aar'

如果您使用的是 multidex，那么也可能会出现此问题。但在较低版本的手机中。

您需要做的就是按照此处给出的步骤进行操作:
