Description

I have an issue with the app memory leak in MainActivity when running the foreground service
the

Steps to reproduce
  • my app is running foreground service so when I repeat it about 30 times close -> open -> it causes a memory leak does the react native screen have an option to destroy the screen?
  • I keep the Android process running but when I close (swipe the app out normally in Android swipe the app out it would be killed) and open the app it increases the app memory do we have the option to destroy it?

调研方向

从链接的 reproducer 以及 Android 前台服务在 React Native 0.73.6 上运行时的 MainActivity 生命周期入手。重复报告中的关闭并重新打开流程,测量内存保留情况,并确定 MainActivity 是否仍被保留;完成的标准是有证据表明已隔离该泄漏,并且其生命周期行为已得到修复或明确记录。
