AndroidX迁移后应用启动崩溃问题求助

应用迁移至AndroidX后启动崩溃，抛出异常如下：

可能的原因及解决方法 #

• 校正onCreate执行顺序：异常核心提示需在组件的super.onCreate之后调用consumeRestoredStateForKey。检查所有Activity、Fragment的onCreate方法，确保自定义逻辑（尤其是涉及状态恢复的代码）全部放在super.onCreate(savedInstanceState)之后执行。

• 升级AndroidX依赖版本：旧版AndroidX组件存在生命周期同步bug，将lifecycle-runtime、savedstate相关依赖升级到最新稳定版，示例gradle配置：

  implementation 'androidx.lifecycle:lifecycle-runtime:2.6.2'
  implementation 'androidx.savedstate:savedstate:1.2.1'
  

• 排查自定义状态恢复逻辑：如果自己实现了SavedState相关功能，检查是否在错误的生命周期阶段调用了consumeRestoredStateForKey，严格遵循组件生命周期流程，避免在super.onCreate之前触发。

• 检查第三方库兼容性：部分未适配AndroidX的第三方库会干扰生命周期回调。排查项目依赖，将第三方库升级到支持AndroidX的版本，替换掉完全不兼容的库。

• 清理编译缓存并重建：执行Clean Project和Rebuild Project操作，清除旧编译缓存，确保所有AndroidX类被正确引用。
