java.io.exception

[abner69]

Hello folks, Hoping someone can help me with this..

Everytime I attempt to copy files from assets to the external storage on this first generation Motorola droid, I get the following Error:

An error occurred in sub db_copyfromassets(java line: 82)
java.io.exception
continue?

I have verified that there is 1.86GB free on the SD Card... It is writing other files to the defdirexternal, but errors when attempting to put into the subdir. I see no permission denied errors, so am stumped.

the code i am using is as follows:

'Excerpt from My Class RES
Sub CopyDBFromAssets (FileName As String,SubDir As String, ForceCopy As Boolean) As String
   Dim TargetDir As String
   'Log("Checking where we can write to...")
   If File.ExternalWritable=True Then TargetDir = File.DirDefaultExternal Else TargetDir = File.DirInternal
   'Log("Writing to: " & TargetDir)
   
   'Check to See if Directory Exists...If Not Create it
   'Log("Checking to see if directory exists")
   If File.IsDirectory(TargetDir & "/" & SubDir,"test")=False Then
   File.MakeDir(TargetDir,SubDir)
   'Log("Created directory...")
   Else
   'Log("Directory existed!")
   End If

      TargetDir=TargetDir & "/" & SubDir
   
   If File.Exists(TargetDir, FileName) = False OR ForceCopy=True Then
      File.Copy(File.DirAssets, FileName, TargetDir, FileName)
   End If
   Return TargetDir
End Sub

I am calling the routine with this:

'Activity SysLoader
Sub Globals
dim res as RES 'My Class
dim tBiblePath as String
end Sub

Sub Activity_Create(FirstTime As Boolean)
tBiblePath="bibles"
EBSystem.BiblePath=res.CopyDBFromAssets("amp_bible.db",tBiblePath,True)
End Sub

my Tracelog is as follows:
I am running this code on 3 different versions of LG, y HTC without difficulties

What is the size of this file? There is a bug in Android where it fails to copy files larger than 1mb. It is related to the compression method used.

The solution is to rename the file from amp_bible.db to amp.bible.zip. This will prevent the packager from compressing the file and will solve this issue.

thanks for the reply @Erel...

You are correct, the bible dbs are between 4-6MB ....

I did a suggested, and renamed them... Once again, all works fine except on these Motorola Droids... (I borrowed a second droid to make sure that it just wasnt a problem fone.) Same error - java.io.exception

...Any other Ideas?

Rename the file to amp_bibles.jpg.
