Firebase In App Messaging 不适用于 Android OS 6.0.1

Question

我正在尝试在我的 Android 应用程序中集成 Firebase InApp 消息传递。在 gradle 中添加以下依赖项后 实施'com.google.firebase:firebase-inappmessaging-display:18.0.2'

抛出以下错误： 致命异常：RxCachedThreadScheduler-1 io.reactivex.exceptions.UndeliverableException：无法将异常传递给消费者，因为它已经取消/处理了流程，或者异常无处可去。进一步阅读：https://github.com/ReactiveX/RxJava/wiki/What's-different-in-2.0#error-handling | java.lang.NoClassDefFoundError: com.google.common.base.CharMatcher 在 io.reactivex.plugins.RxJavaPlugins.onError（RxJavaPlugins.java:367） 在 io.reactivex.internal.schedulers.ScheduledRunnable.run（ScheduledRunnable.java:69） 在 io.reactivex.internal.schedulers.ScheduledRunnable.call(ScheduledRunnable.java:57) 在 java.util.concurrent.FutureTask.run(FutureTask.java:237) 在 java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(ScheduledThreadPoolExecutor.java:154) 在 java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:269) 在 java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1113) 在 java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:588) 在 java.lang.Thread.run(Thread.java:818) 引起：java.lang.NoClassDefFoundError: com.google.common.base.CharMatcher 在 com.google.common.base.Splitter.on(Splitter.java:125) 在 io.grpc.internal.GrpcUtil.(GrpcUtil.java:203) 在 io.grpc.internal.AbstractManagedChannelImplBuilder.(AbstractManagedChannelImplBuilder.java:84) 在 io.grpc.okhttp.OkHttpChannelBuilder.forTarget(OkHttpChannelBuilder.java:119) 在 io.grpc.okhttp.OkHttpChannelProvider.builderForTarget(OkHttpChannelProvider.java:48) 在 io.grpc.okhttp.OkHttpChannelProvider.builderForTarget(OkHttpChannelProvider.java:27) 在 io.grpc.ManagedChannelBuilder.forTarget（ManagedChannelBuilder.java:73） 在 com.google.firebase.inappmessaging.internal.injection.modules.GrpcChannelModule.providesGrpcChannel(com.google.firebase:firebase-inappmessaging@@18.0.2:41) 在 com.google.firebase.inappmessaging.internal.injection.modules.GrpcChannelModule_ProvidesGrpcChannelFactory.providesGrpcChannel(com.google.firebase:firebase-inappmessaging@@18.0.2:36) 在 com.google.firebase.inappmessaging.internal.injection.modules.GrpcChannelModule_ProvidesGrpcChannelFactory.get(com.google.firebase:firebase-inappmessaging@@18.0.2:26) 在 com.google.firebase.inappmessaging.internal.injection.modules.GrpcChannelModule_ProvidesGrpcChannelFactory.get(com.google.firebase:firebase-inappmessaging@@18.0.2:9) 在 dagger.internal.DoubleCheck.get(DoubleCheck.java:47) 在 com.google.firebase.inappmessaging.internal.injection.components.DaggerUniversalComponent.gRPCChannel(com.google.firebase:firebase-inappmessaging@@18.0.2:280) 在 com.google.firebase.inappmessaging.internal.injection.components.DaggerAppComponent$com_google_firebase_inappmessaging_internal_injection_components_UniversalComponent_gRPCChannel.get(com.google.firebase:firebase-inappmessaging@@18.0.2:437) 在 com.google.firebase.inappmessaging.internal.injection.components.DaggerAppComponent$com_google_firebase_inappmessaging_internal_injection_components_UniversalComponent_gRPCChannel.get(com.google.firebase:firebase-inappmessaging@@18.0.2:424) 在 com.google.firebase.inappmessaging.internal.injection.modules.GrpcClientModule_ProvidesInAppMessagingSdkServingStubFactory.get(com.google.firebase:firebase-inappmessaging@@18.0.2:35) 在 com.google.firebase.inappmessaging.internal.injection.modules.GrpcClientModule_ProvidesInAppMessagingSdkServingStubFactory.get(com.google.firebase:firebase-inappmessaging@@18.0.2:11) 在 dagger.internal.DoubleCheck.get(DoubleCheck.java:47) 在 com.google.firebase.inappmessaging.internal.GrpcClient_Factory.get(com.google.firebase:firebase-inappmessaging@@18.0.2:23) 在 com.google.firebase.inappmessaging.internal.GrpcClient_Factory.get(com.google.firebase:firebase-inappmessaging@@18.0.2:8) 在 dagger.internal.DoubleCheck.get(DoubleCheck.java:47) 在 com.google.firebase.inappmessaging.internal.ApiClient.getFiams(com.google.firebase:firebase-inappmessaging@@18.0.2:8)

这适用于其他 Android 操作系统，已通过 7.0、8.0 和 9.0 验证。 注意：已添加 androidx 支持。

这些是我的 gradle 依赖项：

    implementation 'io.reactivex:rxandroid:1.2.1'
    implementation 'io.reactivex:rxjava:1.3.0'
    implementation 'androidx.recyclerview:recyclerview:1.0.0'

有人遇到过这个吗？

尝试将 Guava 添加到依赖项中，似乎可以解决问题：

implementation 'com.google.guava:guava:29.0-android'
