androidx和v4包资源冲突解决方法，Androidx与v4包资源冲突解决方案

摘要：关于Android开发中，AndroidX和v4包资源冲突的问题，可以通过以下方式解决。识别冲突的具体资源，了解冲突产生的原因。采用排除法逐一排查资源冲突问题。解决策略包括替换冲突资源、调整资源命名或使用条件判断来避免冲突。确保更新依赖库至最新版本，避免遗留问题。开发者还需注意在迁移至AndroidX时遵循最佳实践，确保平滑过渡。通过以上方法，可有效解决AndroidX和v4包资源冲突问题。

一、资源包会报如下错误：

错误类似 (androidx.core:core:1.10.0) 和 (com.android.support:support-compat:24.2.0)

表示资源重复，不知调用androidx包下面的，还是v4包下面的

二、 解决方法

2.1 在gradle.properties中只添加了android.useAndroidX=true(表示当前项目启用 AndroidX)

2.2 添加android.enableJetifier=true(表示将依赖包也迁移到AndroidX，将项目中用到的第三方库中的support引用转为androidx引用) 即可

android.useAndroidX=true
android.enableJetifier=true
