Firebase android 性能 NoClassDefFoundError -> FirebasePerfUrlConnection

Question

有人面临同样的问题吗？将 firebase 性能添加到项目后，启动应用程序后立即发生错误。它仅在调试版本中崩溃，在发布版本中一切都按预期工作。也许有人有真正的答案，因为我在类似问题中发现的所有内容都是通过试错方法来处理库版本。Multidex 已打开。

Answer 1

包含所有或删除所有这些

构建 Gradle（应用程序名称）

dependencies {
    classpath 'com.google.firebase:perf-plugin:1.3.4'
}

构建 Gradle（：应用程序）

在页面顶部

apply plugin: 'com.google.firebase.firebase-perf'

然后

dependencies {
    implementation 'com.google.firebase:firebase-perf:19.1.0'
}

Answer 2

最新版本的 firebase 工作完美。这是示例：

依赖项：

implementation platform('com.google.firebase:firebase-bom:28.2.1')
releaseImplementation 'com.google.firebase:firebase-analytics-ktx'
releaseImplementation 'com.google.firebase:firebase-crashlytics-ktx'
releaseImplementation 'com.google.firebase:firebase-perf-ktx'
