Flutter 應用程序在沒有靜態方法 isAtLeastR 的情況下在 android 10 和 R 上崩潰

Question

我在堆棧溢出上看到了一些類似的問題，但沒有一個與相同的庫完全相關。

我正在嘗試在 flutter flutter_geofence 和 geolocator 中使用 2 個插件

它們都運行良好，但從昨天開始，只要調用位置播放服務，我就會退出應用程序，並顯示類似於以下的堆棧跟蹤：

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

我見過的其他參考資料提到了 com.google.android.gms:play-services-base 的特定版本導致此問題，但它已在 com.google.android.gms:play-services-base:17.2.1 中修復

這些庫都沒有在他們的 build.gradle 文件中實現那個包，所以我不知道需要做什么來解決這個問題。

Answer 1

在 app/build.gradle 添加com.google.android.gms:play-services-base:17.2.1這應該使庫使用特定版本的播放服務。

如果它沒有幫助，可能需要

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

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

根據安德魯斯的建議編輯：

17.2.1 不起作用，但 17.0.0 起作用。

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' 
        }           
}

這就是為我解決的問題。
