MemoryPressureMonitor

System memory pressure observer for Android.

Listens to system ComponentCallbacks2.onTrimMemory events and maintains a state indicating whether the device is under critical memory pressure.

Functions

Checks if the device is currently under critical memory pressure.

Called by the OS on device configuration changes; not a memory signal, so a no-op here.

open override fun onLowMemory()

Called by the OS under severe memory pressure; always marks critical.

open override fun onTrimMemory(level: Int)

Called by the OS as memory pressure rises or falls; updates the critical flag accordingly.

Registers this monitor with the application Context.
