Description

The list of methods to do Memory Available are organized into topic(s).

Method

longavailableMemory()
Returns the amount of available memory (free memory plus never allocated memory). 
return RUNTIME.freeMemory() + RUNTIME.maxMemory() - RUNTIME.totalMemory();
longavailableMemory()
Determine the amount of available memory. 
Runtime rt = Runtime.getRuntime();
return rt.maxMemory() - rt.totalMemory() + rt.freeMemory();
longavailableMemory()
Returns the amount of available memory (free memory plus never allocated memory). 
return Runtime.getRuntime().freeMemory()
        + (Runtime.getRuntime().maxMemory() - Runtime.getRuntime().totalMemory());
floatavailableMemoryPercent()
Returns the amount of available memory in percents. 
return availableMemory() * 100.0f / Runtime.getRuntime().maxMemory();
longgetAvailableMemory()
Gets the available memory. 
Runtime runtime = Runtime.getRuntime();
int max = (int) (runtime.maxMemory() / 1024 / 1024);
int total = (int) (runtime.totalMemory() / 1024 / 1024);
int free = (int) (runtime.freeMemory() / 1024 / 1024);
free = free + max - total;
int used = max - free;
return free;
longgetAvailableMemory()
get Available Memory 
Runtime runtime = Runtime.getRuntime();
long maxMemory = runtime.maxMemory();
long allocatedMemory = runtime.totalMemory();
long freeMemory = runtime.freeMemory();
return freeMemory + (maxMemory - allocatedMemory);
longgetAvailableMemory()
get Available Memory 
long freeMemory = Runtime.getRuntime().freeMemory();
return getMaximumMemory() - freeMemory;
longgetAvailableMemory()
TODO TEST!! 
Runtime rt = Runtime.getRuntime();
long maxMem = rt.maxMemory();
long freeMem = rt.freeMemory();
long totalMem = rt.totalMemory();
long used = totalMem - freeMem;
long available = maxMem - used;
return available;
doublegetAvailableMemoryFraction()
get Available Memory Fraction 
Runtime runtime = Runtime.getRuntime();
long maxMemory = runtime.maxMemory();
long allocatedMemory = runtime.totalMemory();
long freeMemory = runtime.freeMemory();
return (double) ((freeMemory + (maxMemory - allocatedMemory))) / maxMemory;
longgetAvailableMemorySize()
Get available memory size 
long maxMemorySize = 512 * 1024 * 1024;
if (Runtime.getRuntime().maxMemory() > maxMemorySize) {
    maxMemorySize = Runtime.getRuntime().maxMemory();
long freeMemorySize = Runtime.getRuntime().freeMemory();
long totalMemorySize = Runtime.getRuntime().totalMemory();
long usedMemorySize = totalMemorySize - freeMemorySize;
return maxMemorySize - usedMemorySize;
