Sorry, I have no idea why it can't find Android Studio and SDK on my system. I have them installed, and updated recently to 2023.1.1 from November 9, 2023.

调研方向

从链接的 jcubic/react-native-text-input 复现示例开始,使用带样式的 children 进行受控 selection,复现 Android 故障。在移动光标时,对比基于 children 的 input 与基于 value 的 input。完成标准是:selection 发生变化后,带样式的 children 仍保持可见,包括存在初始 value 的情况。
