J2ME and N8 - pointerPressed, pointerReleased freezes

[mariozorz]

Hi all

I'm having an issue with the N8 on a J2me app implementing the Canvas class: it seems that, when I touch the screen rapidly, the pointerPressed and pointerReleased J2ME event methods never get called, and moreover the application freezes. If I had a thread updating the UI it just stops and no further information is given - I have System.err.println() calls immediately as soon as pointerPressed or pointerReleased are entered, but none sill show.

Same happens on the Symbian^3 SDK emulator.

Unfortunately I couldn't get a simple test working - it will just eventually happen, sooner than later (sometimes even at first touch).

Anyone has come accross this problem and solved it already? Any ideas?

Thanks
Mario

Aha!.

Ok, found a solution to this. As a matter of fact, I was performing lengthy operations in the pointerReleased method call. Only that I never thought this could be such a problem for the Symbian^3 JVM implementation, as it's working just fine on S60 5th edition handsets.

Nevertheless, what I did is implement and start a thread with the supposedly "heavy" code part, so I could return from the pointerReleased method ASAP.

It's working like a charm now.

Hope this helps if you find the same problem!

Best,
Mario
