android编译错误AAPT: error: resource android:attr/lStar not found解决

一、问题描述

国庆放假回来,编译项目突然间就编译不通过了,报错如下

AAPT: error: resource android:attr/lStar not found.

二、解决方式如下

在工程中app/build.gradle中的dependecies上面添加如下代码:

configurations.all {
        resolutionStrategy {
            force 'androidx.core:core:1.6.0'
            force 'androidx.core:core-ktx:1.6.0'
        }
    }

三、别高兴的太早,请往下看!!!

当我还沉浸在编译通过的喜悦当中时,直接当头一棒,竟然直接crash了,报错如下:

解决办法如下:

configurations.all {
        resolutionStrategy.eachDependency {
            DependencyResolveDetails details ->
                def requested = details.requested
                if (requested.group == "androidx.appcompat") {
                    if (requested.name == "appcompat") {
                        details.useVersion "1.3.1" 
                }
        }
    }
