问题
I was wondering, whether is AndroidHttpClient thread safe, as this is not being mentioned in documentation. Means, a single instance of AndroidHttpClient can be shared among multiple threads.
回答1:
Yes, it is thread safe.
AndroidHttpClient is a special implementation of DefaultHttpClient which is pre-configured for Android. It registers the ThreadSafeClientConnManager which allows thread safe HTTP access via a managed connection pool. AndroidHttpClient also applies reasonable default settings for timeouts and socket buffer sizes. It also supports HTTPS by default.
You can find the source code here.
回答2:
It is Thread safe according the code, since it uses
ClientConnectionManager manager =
new ThreadSafeClientConnManager(params, schemeRegistry);
as per source
The only drawback to this is that it's Api level 8 and above (2.2.x)
回答3:
Yes it's thread safe. Also, be sure to use the factory method:
newInstance(String userAgent, Context context)
when using it with HTTPS to ensure caching of SSL sessions.
