Android Question parsing a bunch of string takes way too long

[mcorbeel]

I'm writing an app that communicates with a webserver. I send a POST and the response is a bunch of lines, delimited with CR. These can be 100 to 200 lines. This response has to be parsed and accordingly saved into a db on the device. The problem is that this parsing is so slow. Getting the data from the server takes only a second, parsing the response takes up to 10 seconds. Is this normal? Is there a way to speed things up?

You should send the data from the server as json-array. That can be really fast used in your app.

OR

Your code that you are using is to slow ;-)

Maybe show your code and we can have a look what need so much time....

In one of my apps there are 500 DB-Entries that came as json-array from the server... It needs a few seconds to build the complete scrollview with this data...

Well I put some logging in, and it's definitely the parsing that takes so long. Constructing the scrollview is fast enough.
I'll have a look into json. That's new to me. Thanks

Show your parsing code which splits the lines into data... Maybe we can give a suggestion to make it faster.

Parsing 100-200 lines should not take 10 seconds. Are you testing it in rapid debug mode? This mode can be slower.

In the meanwhile I'm beginning with JSON, hope this is faster. But i have a question about JSON, will start a new thread ...
