I'm using Google translator, sorry for the typos.
My scenario is as follows. I have a WebService Restfull and an Android client using Jersey and JSON in Java. Can receive data and send them, my doubts are:
How receive JSON strings of images and saves it to a directory on WebService?
I need examples of methods that perform this task.
You can parse the image from json using AsyncTask to get the image from the server and convert it into the bitmap and set it in your views.
Below are some of the examples which shows how to load image from JSON response:

i have been trying to connect mysql db with android app, and through json i cannot connect it, is it ok not to use json or use any method without json ?
You never needed JSON. You could use XML instead, or create your own serialized format.
The purpose of using a web API (assuming you are using PHP + MySQL) is that you should not use JDBC directly from the Android app

I need to develop a web-service. Purpose of this service is read a oracle blob field(stores image file) and send to the client. Do you think which format is suitable for this blob field. If i send byteArray type, can client convert this to image. This method easy i can do that but according to the my google research image files or other file types can be sent url download link. Which is more sensible? My environment: j2ee,cxf,eclipse,soap
In your wer-service read it as BLOB and then to Byte Array.
but to send it in response, you may need to put it in a proper content-type i.e either "image/jpeg" or "image/png" or whatever is right.
And also , you may need to send it as attachment in your response.
If its SOAP service then, SOAP with Attachement

I used a library called HTMLParser before. It can read html input and generate HTML nodes. You can then analyze and retrieve the node you like.
