android中是否存在任何事件或方法来检查内存是否低？

import android.app.ActivityManager;
import android.content.Context;
import android.os.Build;
import android.os.Debug;
import android.os.MemoryInfo;

public class MemoryChecker {

    public static boolean isMemoryLow(Context context, int thresholdInMB) {
        ActivityManager.MemoryInfo memoryInfo = new ActivityManager.MemoryInfo();
        ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        activityManager.getMemoryInfo(memoryInfo);

        long availableMemory = memoryInfo.availMem / (1024 * 1024); // Convert to MB

        return availableMemory< thresholdInMB;
    }
}
