android - Android 6 和 5 上的 Firebase InApp 消息传递崩溃

Question

我的应用程序在打开时因此错误而崩溃，仅在 Android 6 和 Android 5 上:

这是我的毕业设置:

compileSdkVersion 28
buildToolsVersion '28.0.3'
defaultConfig {

    ...

    minSdkVersion 21
    targetSdkVersion 28

    ...

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    vectorDrawables.useSupportLibrary = true
    multiDexEnabled true

}

我正在使用最新版本的 Firebase InApp 消息传递
implementation 'com.google.firebase:firebase-inappmessaging-display:19.0.3'
我已经发现了这些问题，但没有解决方案:

https://github.com/firebase/firebase-android-sdk/issues/630

https://github.com/firebase/firebase-android-sdk/issues/1124

有没有人有同样的问题？

更新

我解决了将 Google Guava 库添加到 gradle 的问题
implementation "com.google.guava:guava:28.2-android"

Answer 1

Use the below dependency to fix the issue

要使用 Gradle 添加依赖项，请使用以下命令:

implementation "com.google.guava:guava:28.2-android"

对于最新的 Guava 库，请参阅 documentation .
