Flutter应用在Android 10& amp;上崩溃没有静态方法的R isAtLeastR
我已经看到了一些与Stack溢出类似的问题,但是没有一个与同一个库有很大关系的问题.
I've seen a few issues similar on Stack overflow, but not one that quite relates to the same libraries.
我正试图在flutter中使用2个插件 flutter_geofence和geolocator
I'm trying to use 2 plugins in flutter flutter_geofence and geolocator
他们俩都运行良好,但是从昨天开始,一旦位置调用服务被调用,我就退出了该应用程序,其堆栈跟踪类似于以下内容:
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:
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)

因此,它抱怨缺少isAtLeastR方法
So it's complaining about a missing method isAtLeastR
我见过的其他参考文献都提到了com.google.android.gms:play-services-base的特定版本,这是导致此问题的原因,但它已在com.google.android.gms:play-services-base中修复: 17.2.1
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
这两个库都不在其build.gradle文件中实现该程序包,因此对于解决此问题需要做什么我一无所知.
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.
在app/build.gradle中添加com.google.android.gms:play-services-base:17.2.1
,这应使库使用特定版本的播放服务.
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.
如果没有帮助,则可能需要
If it doesn't help, might need to
configurations.all {
resolutionStrategy {
force 'com.google.needed_dependency'
}
}

根据安德鲁斯的建议进行
Edit as per Andrews suggestion:
17.2.1不起作用,但17.0.0起作用.
17.2.1 doesn't work, but 17.0.0 does.
implementation("com.google.android.gms:play-services-base:17.0.0"){ force = true }
