android - JSONString won't convert to JSONArray

Question

I am attempting to send a string json of teams through Bluetooth to another android device. For some reason the Serializer will load a small list of teams but a large list of teams causes this error:

Answer 1

The problem appears to be that your data is getting chunked, and you are trying to parse those chunks individually.

There are number of ways to approach this problem. One easy way would be to use ObjectInputStream and ObjectOutputStream instead of plain InputStream and OutputStream. The Object stream variants will handle ensuring that you are sending and receiving complete objects, so if you send a String in an output stream, you should get the complete stream back on the other side in the input stream.

Assuming you are sending the JSON as a String (and it is UTF-8 encoded), sending the JSON is as easy as calling writeUTF(String), then reading it using readUTF().
