Problem in HTTPUtils

[Kevin]

I've been seeing the following lately in my dev console. Not sure why this would suddenly be a problem though, as it seems to be a problem getting DirInternalCache....

Do you know on which device this error happened?

There seems to be an issue with Context.getCacheDir returning null (File.DirInternalCache is based on this method).
android - Cache directory doesn't exist - Stack Overflow

The crash reports don't tell me which device it happened on and as usual, the notes people left are not helpful.

What would be the best way to work around? Can I pop up a message box from a service? I guess uninstalling then reinstalling sometimes fixes it.

You can change Service_Create to:

Sub Service_Create
   If init = False Then Process_Globals
   Try
      If TempFolder = "" Then TempFolder = File.DirInternalCache
   Catch
      TempFolder = File.DirInternal
   End Try
   If hcIsInitialized = False Then
      hc.Initialize("hc")
      hcIsInitialized = True
   End If
End Sub

Digging up an old thread here, but I had made the changes as suggested which seemed to stop those errors completely.

Then I saw this new one today. I don't know what device it is on, but apparently this one can't locate DirInternal either. :sign0094:

What's left to try after those two? DirExternal?

Note that the original error cannot happen anymore as DirInternalCache returns DirInternal if the cache folder is not available.

The DirInternal issue seems like a bug in Android: Issue 8886 - android - sometimes context.getFilesDir() returns null - Android - An Open Handset Alliance Project - Google Project Hosting
