android上最多有多少个http连接？

1.使用HttpUrlConnection能有几个

　　测试机器版本是5.1.1

个数网络连接是否报错写文件是否报错 1024 

A/art: art/runtime/indirect_reference_table.cc:77]

nullptr ashmem_create_region failed for 'indirect ref table':

360看网络环境，有时报错

2.使用okhttp有几个

同一个 url最大 5个连接一个client最多64个网络连接

3.使用volley有几个

　　在RequestQueue.java中 

1 /** 2 * The set of all requests currently being processed by this RequestQueue. A Request 3 * will be in this set if it is waiting in any queue or currently being processed by 4 * any dispatcher. 5 */ 6 private final Set<Request<?>> mCurrentRequests = new HashSet<Request<?>>();

　　用的HashSet,在它的构造函数注释中有:默认容量是16,装载因子是0.75.

1 /** 2 * Constructs a new, empty set; the backing <tt>HashMap</tt> instance has 3 * default initial capacity (16) and load factor (0.75). 4 */ 5 public HashSet() { 6 map = new HashMap<>(); 7 }
