Android Question Interstitiate Ad and Dirinternal files

06Pierrick06 · May 8, 2020

Hi Forum

My B4A application worked perfectly until I added an interstitiate AD before I open a file in Dirinternal.

Each time the Ad is displayed, the file disappears in DirInternal (!).
If I comment the "IAd.show" command, the file is kept (!)

Any idea what could be the reason ?

B4X:

'Download file from Dropbox when "Activity_create.FirstTime=True"
dbx.Download("/catalog.db",File.DirInternal,"catalog.db")

(...)

'Display Interstitiate when ready
If IAd.Ready Then
        IAd.Show
End If

If File.Exists(File.DirInternal,"catalog.db")=False Then
        Log("Bug : The file disappeared !")
end if

'As a result, this instruction crashes with IAd.show due to file removed
sql2.Initialize(File.DirInternal,"catalog.db",False)

Maybe the IAd solution will empty its directory. Have you tried moving the database to a different directory?

The problem is somewhere else. My guess is that you are waiting for an event and then other code in other subs is running before the file was saved.

Changing the directory did not solve the issue.

I found that the intial delete+download of my DB file did not complete on time.
I have added 2 infinite loops to ensure file delete and file download are complete before going forward and it solved the issue.

I still don't understand why the bug appeared with an interstitial Ad but my code was definitively wrong.

Thanks for your help !

B4X:

If File.Exists(File.Dirinternal,"catalog.db") Then
    File.Delete(File.Dirinternal,"catalog.db")
    Do While File.Exists(File.DirInternal,"catalog.db")=True
    Sleep(0)
    Loop               
End If               

dbx.Download("/catalog.db",File.DirInternal,"catalog.db")

'On attend le fichier
Do While File.Exists(File.DirInternal,"catalog.db")=False
    Sleep(0)
Loop

I found that the intial delete+download of my DB file did not complete on time.

You could try to implement OkHttpUtils2 with Wait For in the dbx code, so you can be sure that the Db is fully loaded
