iOS Question Several Errors in Debug, not in Release

[schimanski]

Since yesterday, I have the problem, that my app runs in release, but suddenly not in debug mode. There are several exceptions. I have cleaned the project 10 times, I have deleted the app 5 times and I have deinstalled and new installed b4i-Bridge. I also tried to set back from 64bit to 32Bit and I have tried to install an old version of my app, to make sure that it is not a new modul...all that doesn't helps:

Here are two exceptions, that only are raised in debug:

Does anybode knows, what I can also do to solve the problem?

 

[JonPM]

Can you show your code surrounding the above errors (initialization of ExpandableTableView and clsPMEditText)?

 

[schimanski]

Hello JonPM. The code is the original class of Erel's ExpandableTableView and the the clsPMEditText is the original Class of filippos Preference. The problem isn't this code, because everything runs with the same code in debug yesterday. I think, that something is crashed in the compiler settings. The same problem is often posted here and an deinstallation and new installation solved this problem, but not yet...

 

[JonPM]

Oh do you mean with Hosted Builder? Sorry I use local so I'm not sure

 

[schimanski]

Yes, I'm using hosted...

 

[Erel]

Such errors are almost never related to reinstallation of B4i..
Uninstalling the app from the device and then installing it again can solve an issue with files not being updated.

The second error means that there is a missing bitmap.
It happens in: clspmedittext.initialize

 

[schimanski]

Yes, I know that. I have uninstalled everything up to 10 times, but nothing helps. The missing bitmap is only the first exception. When I delete the line, the next bitmap in the dirassets folder isn't found in debug. I had the problem sometimes in the past and an reinstall helps every times, but now, no success...

 

[Erel]

Are there several "debug" apps (with different package names) installed on your device?

 

[schimanski]

Not yet. I always uninstall them, when I don't need them longer. Could a factory reset solve the problem?

 

[Erel]

Could a factory reset solve the problem?

I don't think that it will help.

If you can reproduce it then please send me the complete project and I'll check it.

 

[Erel]

In debug mode the asset files are stored in a folder named virtual_assets. It is located in the temp folder.

Your current code deletes this folder together with the other temporary files.
Change the sub that deletes all the temporary files to:

Sub TempFiles_loeschen
   For Each s As String In File.ListFiles(File.DirTemp)
     If File.IsDirectory(File.DirTemp, s) = False Then
       File.Delete(File.DirTemp, s)
     End If
   Next
End Sub

 

[schimanski]

Much thanx, Erel. I think, I wouldn't come out.

 

[Erel]

I will explain how I debugged this issue.

First I added this line right before the LoadBitmap that fails:

Log(File.ListFiles(File.DirAssets))

It failed.

So I added the same line right at the beginning of Application_Start.
This time it worked. So I understood that the folder is deleted somewhere.

The next step was to search for File.Delete.
