Android Question File.DirAssets returns AssetsDir as string text

[MicroDrie]

I use B4A version 9.50 and B4A Bridge version 2.60. I am having problems with the Log command ("DirAssets:" & File.DirAssets). This returns the string text "DirAssets: AssetsDir".

    Log("DirAssets: " & File.DirAssets)
    Log("DirDefaultExternal: " & File.DirDefaultExternal)
    Log("DirRootExternal: " & File.DirRootExternal)
    Log("DirInternal: " & File.DirInternal)
    Log("DirInternalCache: " & File.DirInternalCache)

The result is:
Logger connected to: samsung SM-J730F
--------- beginning of main
*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
DirAssets: AssetsDir
DirDefaultExternal: /storage/emulated/0/Android/data/b4a.example/files
DirRootExternal: /storage/emulated/0
DirInternal: /data/user/0/b4a.example/files
DirInternalCache: /data/user/0/b4a.example/cache
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
** Service (starter) Destroy (ignored)**
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **


How can I solve this challenge so that I get the correct memory location from the Assets directory is returned?

It is not relevant. It depends on which sdcard the app is installed (internal or external).

If you want to access a file in the Filesdir you should use File.DirAssets.

What are you trying to archieve?

I load an html file into a webview element to insert once loaded information.

    Log("DirAssets: " & File.DirAssets)
   Log("DirDefaultExternal: " & File.DirDefaultExternal)
   Log("DirRootExternal: " & File.DirRootExternal)
   Log("DirInternal: " & File.DirInternal)
   Log("DirInternalCache: " & File.DirInternalCache)
       
   If FirstTime = True Then
       If File.Exists(File.DirDefaultExternal,"*.html") = False Then
           File.Copy(File.DirAssets,"index.html", File.DirDefaultExternal,"index.html")
           File.Copy(File.DirAssets,"style.css", File.DirDefaultExternal,"style.css")
           File.Copy(File.DirAssets,"script.js", File.DirDefaultExternal,"script.js")
       Else
'               dd
       End If
   End If

This are the results:

I also do not understand where this text comes from: [com.lttech.md4x]

 

[DonManfred]

it is your packagename
I dont see a code posted which raises this error.

Loading HTML file in WebView from Assets requires special handling. See https://www.b4x.com/android/forum/t...-from-assetsdir-in-webview.78500/#post-497506.

This returns the string text "DirAssets: AssetsDir".

Makes sense, since Assets directory is special, since it is part of/internal to your APK

Studying the answers given led to the insight that the elaboration of an HTML solution imposes limitations. The CSS layout and the JS should both be in-line. In practice, the layout with $ "" $ big string could run against the limit of approximately 64000 characters.

I take a new approach based on a local web server. This has the benefit of divided the logical program flow and presentation layer based on Erel's HTTP server example.
By changing:

Sub Server_HandleRequest (Request As ServletRequest, Response As ServletResponse)
   Try
       Log("Client: " & Request.RemoteAddress & ", Request: " & Request.RequestURI)

in ServerService to

Sub Server_HandleRequest (Request As ServletRequest, Response As ServletResponse)
   Try
       Log("Client: " & Request.RemoteAddress & ", Request: " & Request.RequestURI)
'       Limit respons to local users only
       Dim ssocket As ServerSocket
       If ssocket.GetMyWifiIP <> Request.RemoteAddress Then
           Log("Non-local user request dropped")
           Return
       End If

I Can limited the use to the local user only to protect the information.
Thank you very much guys, for guiding my.
