如何修复错误“反编译的 .class 文件字节码版本 52.0 (Java 8)

Question

当我在模拟器上测试我的应用程序时，它工作正常，但是当我在真正的 android 10.0（版本）手机上运行应用程序时，log-cat 显示了我根本无法理解的错误。 这非常令人困惑，因为它在一部手机（较低版本）上运行良好，而在另一部手机（Android 10.0 版本）上不起作用。

我收到的错误如下：

反编译的 .class 文件，确切地说是字节码版本 52.00(Java 8)。

错误选项卡中的 Logcat：

Answer 1

如果您使用 com.google.android.gms:play-services-maps:16.0.0 或更低版本，并且您的应用面向 API 级别 28 (Android 9.0) 或更高版本，则必须在 AndroidManifest 的元素中包含以下声明。 xml。

<uses-library
      android:name="org.apache.http.legacy"
      android:required="false" />

如果您使用的是 com.google.android.gms:play-services-maps:16.1.0，这将为您处理，如果您的应用面向较低的 API 级别，则不需要。
