Question

我对Android和Google云相当陌生。我编写了一个成功写入firestore数据库的测试应用程序。我想通过添加一个发布到pubsub主题的功能来扩展我的应用程序。我将以下依赖行添加到build.gradle：

implementation 'com.google.cloud:google-cloud-pubsub:0.33.0-beta'

在我添加任何新的pubsub代码之前，我的应用程序使用以下堆栈跟踪构建，运行并立即崩溃：

我不知道从哪里开始排除故障。一旦我删除了pubsub依赖项，我的代码就会构建并再次正常运行。

Answer 1

根据doc，＆＃34; Google Cloud Java客户端库目前不支持Android＆＃34;。

您可能希望使用Google Cloud Pub/Sub API Client Library替代项目。

将PubSub添加为依赖项会导致Firestore
