实例如下：
//1.获取内存可用大小,内存路径
String path=Environment.getDataDirectory().getAbsolutePath();
String memoryAvaliSpace= Formatter.formatFileSize(this,getAvailSpace(path));
//2.获取sd卡可用大小，sd卡路径
String sdPath=Environment.getExternalStorageDirectory().getAbsolutePath();
String sdAvaliSpace= Formatter.formatFileSize(this,getAvailSpace(sdPath));
private long getAvailSpace(String path) {
//获取可用内存大小
StatFs statfs=new StatFs(path);
//获取可用区块的个数
long count=statfs.getAvailableBlocks();
//获取区块大小
long size=statfs.getBlockSize();
//可用空间总大小
return count*size;
}
