我的应用程序正在将文件保存在SD卡上,但在保存文件之前,我需要检查是否有空闲内存.我需要检查SD卡上有多少可用内存.
就像是：
if(MemoryCard.getFreeMemory()>20Mb)
{
saveFiles();
}
else
{
Toast.makeText(this,"Not enough memory",100).show();
}
解决方法

StatFs stat = new StatFs(Environment.getExternalStorageDirectory().getPath()); long bytesAvailable = (long)stat.getBlockSize() * (long)stat.getBlockCount(); long megAvailable = bytesAvailable / 1048576;
