Android Question Application has stopped

[AHilberink]

Hi,

I have a strange problem: My app is working well on the AVD emulation. On the tablet it gives a error "(AppName) has stopped", but not always.

Looking to the steps during this error, there is no step done.

Is there a way to investigate were it is going wrong? Now I don't have any clue.

Best regards,
André

Have you tried it in Debug mode ?
You should get an error message in the Logs.
Do you load big bitmaps, I suspect an out of memory problem.

Hi Klaus,

Thanks you for your suggestions. I did a try in debug on developer mode on the tablet. I now got an error message:

It seems to happen between a Poststring and the JobDone. JobDone is never reached.

Can someone please explain how to find this problem?

Best regards,

It fails to write to File.DirInternalCache for some reason.

Try to create this folder with:

File.MakeDir(File.DirInternalCache, "")

Hi Erel,

I tried this, but same error and appcrash.

Is there something else to check?

Best regards,

Use HttpUtils2 source code instead of the library and change TempFolder to File.DirInternal.

I just update to v6.30. During compile, I got the following message:

Compiling generated Java code.    Error
javac 1.8.0_40
src\b4a\werkbonnen\httputils2service.java:84: error: cannot find symbol
        super.onTaskRemoved(rootIntent);
             ^
  symbol: method onTaskRemoved(Intent)

What is going wrong?

Best regards,
André
