FileNotFound FC error

[JonPM]

My app is using Map to store settings. I tried it on a different computer with a new emulator and now it is force closing at startup. Log shows:
Caused by: java.io.FileNotFoundException: /data/data/myB4Aprog/files/Map.dat (No such file or directory)

In Activity_Create I am using:

   If File.Exists(File.DirInternal,"Map.dat") = False Then
      Map1.Initialize
      Map1.Put("DefHeight","in")
      Map1.Put("DefWeight","kg")
      File.WriteMap(File.DirInternal, "Map.dat", Map1)
   Else
      Map1 = File.ReadMap(File.DirInternal,"Map.dat")
      DefHeight = Map1.Get("DefHeight")
      DefWeight = Map1.Get("DefWeight")
   End If

What am I doing wrong? I am thinking if the file doesn't exist it will create it with the above values.

 

[Erel]

Your code looks correct. Are you sure that it is failing on:

Map1 = File.ReadMap(File.DirInternal,"Map.dat")

You can choose "Project - Include debug information". The error message will then include the error line.

Here is the entire log. I replaced my actual app name with "myB4Aapp"

[Erel]

Are you running this code from Process_Globals? Sub Process_Globals should only be used for variables declaration.

 

[JonPM]

What code do you mean? The map code is under Activity_Create.

Btw the same app runs fine on my phone. But Fcs on emulator.

[Erel]

According to the stack trace you are trying to load a file from Sub Process_Globals. You should instead load it in Activity_Create, when FirstTime is true.

 

[JonPM]

You're right Erel. I was trying to take a shortcut. Problem fixed, thanks!
