Flutter 应用程序在 android 10 & R 上崩溃，没有静态方法 isAtLeastR

Question

我在 Stack overflow 上看到了一些类似的问题，但没有一个与相同的库完全相关。

我正在尝试在 flutter 中使用 2 个插件 flutter_geofence 和地理定位器

它们都运行良好，但从昨天开始，一旦调用位置播放服务，我就会让应用程序退出，堆栈跟踪类似于以下内容：

E/flutter (11478): [ERROR:flutter/shell/platform/android/platform_view_android_jni.cc(39)] java.lang.NoSuchMethodError: No static method isAtLeastR()Z in class Landroidx/core/os/BuildCompat; or its super classes (declaration of 'androidx.core.os.BuildCompat' appears in /data/app/com.mypossibleself.app-FTu9V5QDAKR_ngQmuPzg7Q==/base.apk!classes2.dex)

所以它抱怨缺少方法 isAtLeastR

我看到的其他参考资料提到了导致此问题的 com.google.android.gms:play-services-base 的特定版本，但它已在 com.google.android.gms:play-services-base:17.2 中修复。 1

这些库都没有在它们的 build.gradle 文件中实现该包，所以我不知道需要做什么来解决这个问题。

Answer 1

在 app/build.gradle 添加 com.google.android.gms:play-services-base:17.2.1 这应该使库使用特定版本的播放服务。

如果没有帮助，可能需要

configurations.all {
    resolutionStrategy {
        force 'com.google.needed_dependency'
    }
}

https://flutter.dev/docs/development/packages-and-plugins/using-packages#conflict-resolution

根据安德鲁斯的建议编辑：

17.2.1 不起作用，但 17.0.0 可以。

implementation("com.google.android.gms:play-services-base:17.0.0"){ force = true }

Answer 2

resolutionStrategy {
            force 'com.google.android.gms:play-services-base:17.1.0' 
        }           
}

这就是为我解决的问题。
