Android Question Error thread, help please

[androidappl]

android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.

The problem stems from the fact that in debug mode does not go astray, while in release mode goes wrong.

 

[Erel]

Are you using the Threading library?

Are you using the Threading library?

Not i use the sub and protocol HTTP, with metode parse "JSON" and find this error:

android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.

 

[Erel]

Can you post the relevant code?

 

[androidappl]

Can you post the relevant code?

There is so much code that is called in several places.
However let's say I solved with some trick ...
The problem amongst other things it appeared only when the application run in release mode, debug mode everything worked ...

 

[Erel]

Your code should always run on the main thread, unless you are doing something "special" like using the Threading library.

I think the problem is that the library webviewextra a problem thread.
Practically exhaust html and using regular expressions recovery data

You can use the Threading library to run code on the main thread. This can be useful if this library raises an event on a different thread.

Oh ok now I understand thank you very much.
If I were to happen again I will follow his advice.

How does the threading library ? if I have to make a http request using the library webviewExtra you an example ? Thank you very much

 

[Erel]

You don't need to use the threading library for http requests. They are handled in the background.

Hi Erel

What about the response from the request. If I am expecting to process some data on the back of a response, will this get done in the background too or in the UI thread?

I'd like to run it so the UI does not freeze up..


Thank you!

Derek.

in the UI thread

 

[Derek Jee]

in the UI thread

Threading library it is then !! Thanks

 

[Erel]

That is not correct. The response is retrieved in the background. Use HttpUtils2 and it will be very simple.

Hi Erel

So if I get a response and need to do processing into a database, format some text do some other events, that this will not be done by the main UI but in a background thread?

Thank you for responding..

 

[Erel]

JobDone event is executed in the main thread. The SQL library does support asynchronous commands.

The first thing to do is to test it and see whether it is fast enough or not.

 

[Derek Jee]

Thank you Erel

I should have been more precise with my question. Yes the response is but the JobDone isn't. I am downloading a text file which I have to process before adding data into my database. It is that processing which needs a separate thread to run in..

Thank you again and looking forward to using version 5..

Derek.
