Android Question Open files with intent

[Pooya1]

Hi
I have problem in open files in android +6
I try use FileProvider but my folder is in root external folder (File.DirRootExternalDir/cache)
But i cannot find correct code in forum
My app is chat application that user can send any file to other user
And other user after download it into root/cache,it is necessary to open file from this folder with intent
Example if file is picture so open it in photo or others
Thanks

In this post you said FileProvider doesn't support it,while user files is in root and i have to open it
Actually i cannot copy user's file in to my folder and open it because maybe user file be more than 10 mb

No. Read the full thread more carefully. Specifically the linked post.

Sorry
I try follow steps

I use below manifest code

'********************  Required for file provider *************************
AddApplicationText(
  <provider
  android:name="android.support.v4.content.FileProvider"
  android:authorities="$PACKAGE$.provider"
  android:exported="false"
  android:grantUriPermissions="true">
  <meta-data
  android:name="android.support.FILE_PROVIDER_PATHS"
  android:resource="@xml/provider_paths"/>
  </provider>
)
CreateResource(xml, provider_paths,
   <external-files-path name="name" path="" />
)
'***************************************************************

For permission and copy file use below code

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("f1")
    Dim rp As RuntimePermissions
    rp.CheckAndRequest(rp.PERMISSION_WRITE_EXTERNAL_STORAGE)
   
End Sub
 
 Sub Activity_PermissionResult (Permission As String, Result As Boolean)
     File.MakeDir(File.DirRootExternal,"cache")
    File.Copy(File.DirAssets,"21.jpg",File.DirRootExternal & "/cache","21.jpg")
 End Sub

For open file use below code

Sub Button1_Click
    Intent_OpenFile(File.DirRootExternal & "/cache","21.jpg")
End Sub

Sub Intent_OpenFile(Dir As String,Filename As String) As Boolean
  
   Try
       Dim ext As String
       ext = Filename.SubString(Filename.LastIndexOf(".")+1)
      
       Dim i As Intent
       i.Initialize(i.ACTION_VIEW,CreateFileProviderUri(Dir,Filename))
       i.SetComponent("android/com.android.internal.app.ResolverActivity")
      
       Dim types As Map
       types.Initialize

       StartActivity(i)
      
       Return True
   Catch
       Return False
   End Try
  
End Sub

The file is copied into folder but i cannot open it from this folder
My error is
Caused by: java.lang.IllegalArgumentException: Failed to find configured root that contains /storage/emulated/0/cache/21.jpg

Again sorry i spent complete 1 day for this but i couldn't did it

1. You should never have an Activity_PermissionResult sub. Use Wait For as demonstrated in the video tutorial.
2. Don't assume that Result will be True.
3. Always post the full error message from the logs.
4. Your manifest code is wrong. As I wrote 3 times you should read this post:
