Lynx
  • English

      • 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.
