Android Question SOLVED: App crashing on Samsung S5

[DouglasNYoung]

Hello oh wise ones,
I have an app which the current version has been running fine since January. Now one user has changed to a Samsung S5 running 4.4.2 and the app crashes on startup. The Crash Report shows

which isn't helping me to to identify the cause of the problem.

Can anybody point me in the right direction?

Thanks in advance,

Does your app use native code?

 

[DouglasNYoung]

Does your app use native code?

NO (well not by me anyway) - Only B4A libraries!

 

[thedesolatesoul]

Looks like a crash in the android native code (not the app). What else do we know?

Thanks for the input 'Thedesolatesoul' - The only info from the user is that the user reports 'It starts to open and then I get a message saying “Unfortunately TM Toolkit has stopped”' on a S5 running 4.4.2

Cheers,
Douglas

Are you showing a modal dialog (or calling DoEvents) in Activity_KeyPress?

Erel,
It shouldn't be as it crashes before getting to the Main Menu, which is just a ListView loaded from a database.
The only thing it does (before the menu) is to get user configuration from a text file and use this to check for data updates on a server. I believe the crash happens before the update check as the server records all requests for updates and there is no record corresponding to this user.

Regards,
Douglas

PS - I'll see if I can get a special version out to the user, over the weekend, which writes a log to file. That way hopefully I can establish which function or sun is causing the problem.

 

[DouglasNYoung]

Problem solved - traced it back to a legacy bit of code where Http.Download is called with the passed parameters build by the app - the user had a space in the configuration data passed in the url string. Result Android crashes!

Thanks for the input,
Douglas

 

[thedesolatesoul]

Android crashes on an Http Call?
If that is really true, you better raise an bug in the Android repo.

 

[DouglasNYoung]

thedesolatesoul,
this must be a well established fact as in the documentation for HTTPUtils states :

• Download2 encodes illegal parameters characters (like spaces)

I was using 'Download' not Download2 and a space had crept it - I find it surprising that it induces a crash, but it does!
