[英]Flutter app crashing on android 10 & R with No static method isAtLeastR
I've seen a few issues similar on Stack overflow, but not one that quite relates to the same libraries.我在堆栈溢出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。
I'm trying to use 2 plugins in flutter flutter_geofence and geolocator我正在尝试在 flutter flutter_geofence 和 geolocator 中使用 2 个插件
They've both been working fine, but since yesterday as soon as of the location play services are called I'm getting the app quit with a stack trace similar to below:它们都运行良好,但从昨天开始,只要调用位置播放服务,我就会退出应用程序,并显示类似于以下的堆栈跟踪:
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)

So it's complaining about a missing method isAtLeastR所以它抱怨缺少方法 isAtLeastR
Other references I've seen to this mention specific versions of com.google.android.gms:play-services-base causing this, but that it's fixed in com.google.android.gms:play-services-base:17.2.1我见过的其他参考资料提到了 com.google.android.gms:play-services-base 的特定版本导致此问题,但它已在 com.google.android.gms:play-services-base:17.2.1 中修复
Neither of these library implement that package in their build.gradle files so I'm at a loss as to what needs doing to fix this issue.这些库都没有在他们的 build.gradle 文件中实现那个包,所以我不知道需要做什么来解决这个问题。
In the app/build.gradle add com.google.android.gms:play-services-base:17.2.1
this should make libraries use specific version of play-services.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。
If it doesn't help, might need to如果它没有帮助,可能需要
configurations.all {
resolutionStrategy {
force 'com.google.needed_dependency'
}
}

Edit as per Andrews suggestion:根据安德鲁斯的建议编辑:
17.2.1 doesn't work, but 17.0.0 does. 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 }
resolutionStrategy {
force 'com.google.android.gms:play-services-base:17.1.0'
}
}
This is what solved it for me.这就是为我解决的问题。
