异常的意思就是说androlidx.fragment的版本发生冲突。
第一种解决办法
产生原因：
"androidx.appcompat:appcompat:${version["androidXSdkVersion"]}"
- 1
因为引入了第三方的库
fragmentationVersion : “1.3.8”
androidXSdkVersion: “1.1.0”
"fragmentation" : "me.yokeyword:fragmentation:${version["fragmentationVersion"]}",
"fragmentation-core" : "me.yokeyword:fragmentation-core:${version["fragmentationVersion"]}",
"fragmentation-swipeback" : "me.yokeyword:fragmentation-swipeback:${version["fragmentationVersion"]}",
- 1
- 2
- 3
所以，App与 me.yokeyword:fragmentation 内发生冲突导致。
百度从 https://blog.csdn.net/EthanCo/article/details/103704527 了解到可能是 “androidx.appcompat:appcompat:${version[“appcompatVersion”]}” 包的冲突。
究竟是不是如此，还需要进一步确认
确认哪个包下的依赖发生冲突

或者，在Terminal终端输入（需要配置ADB）：
gradlew -q app:dependencies

app是应用主工程。
如上即可查看依赖关系。
过程省略，研究的不够透彻…
最后刨掉androidXSdkVersion: “1.1.0” 中fragment 包，即可。
//androidx
api(rootProject.ext.dependencies["appcompat"]) {
exclude module: 'annotation'
exclude module: 'fragment'
}

另一种解决办法
https://blog.csdn.net/EthanCo/article/details/103704527
fragmentationVersion : “1.0.2”
// "fragmentation" : "me.yokeyword:fragmentation:${version["fragmentationVersion"]}",
// "fragmentation-core" : "me.yokeyword:fragmentation-core:${version["fragmentationVersion"]}",
// "fragmentation-swipeback" : "me.yokeyword:fragmentation-swipeback:${version["fragmentationVersion"]}",
"fragmentation" : "me.yokeyword:fragmentationx:${version["fragmentationVersion"]}",
"fragmentation-core" : "me.yokeyword:fragmentationx-core:${version["fragmentationVersion"]}",
"fragmentation-swipeback" : "me.yokeyword:fragmentationx-swipeback:${version["fragmentationVersion"]}",
