Android Question Getting error when copy files

[Ajws]

Hi all, help me....i'm gettting error when copying data this is error message

    If File.Exists(File.DirInternal,"dbpo.db") = True Then
        Msgbox("FOUND","")
      
          File.Copy(File.DirInternal,"dbpo.db",File.DirDefaultExternal ,"dbpo.db")
    End If

java.io.FileNotFoundException: /storage/emulated/0/Android/data/alam.com/files/dbpo.db: open failed: ENOENT (No such file or directory)

File.DirDefaultExternal -> read only ???

1. Don't use Msgbox. Use Log instead.
2. What is the value of targetSdkVersion in the manifest editor?
3. What is the output of Log(File.DirExternalWritable)?

It should be File.ExternalWritable

Anyway, if targetSdkVersion >= 23 then you should use RuntimePermissions.GetSafeDirDefaultExternal instead of File.DirDefaultExternal:

This is my manifest...

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: https://www.b4x.com/forum/showthread.php?p=78136
AddManifestText(
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="23"/>
<supports-screens android:largeScreens="true" 
    android:normalScreens="true" 
    android:smallScreens="true" 
    android:anyDensity="true"/>
     
   
    )
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
 AddManifestText(
<uses-permission
  android:name="android.permission.WRITE_EXTERNAL_STORAGE"
  android:maxSdkVersion="18" />
)

    Log(File.ExternalWritable)  ' ---> return true

but still error

java.io.FileNotFoundException: /storage/emulated/0/Android/data/alam.com/files/dbpo.db: open failed: ENOENT (No such file or directory)
