#trimMemory

Dispatches a memory pressure signal to registered callbacks. Use this to notify Lynx to reclaim resources or apply degradation strategies when the system is under memory pressure.

#Syntax

#Android

@AnyThread
public void trimMemory(@MemoryPressureLevel int pressure);

#iOS

- (void)trimMemory:(LynxMemoryPressureLevel)pressure;

#Harmony

public trimMemory(pressure: MemoryPressureLevel): void;

#Parameters

• pressure: Memory pressure level, one of MemoryPressureLevel.
  • MEMORY_PRESSURE_LEVEL_NONE: No problems, enough memory; typically not sent via callback.
  • MEMORY_PRESSURE_LEVEL_MODERATE: Free buffers that are cheap to re-allocate and not immediately needed.
  • MEMORY_PRESSURE_LEVEL_CRITICAL: Free all possible memory; otherwise the process may be killed by the system, incurring cold start cost.
