Android Question ContentChooser problem

I have a problem with ContentChooser on a Android 7.10 EMULATOR (Genymotion):
--------- beginning of crash

a beutiful crash

This is the code:
B4X: 
Sub ChooseImage
    Private CC As ContentChooser
    If Not(CC.IsInitialized) Then
        CC.Initialize("CC")
    End If
    CC.Show("image/*", "Choose image")
End Sub

I call that routine from Activity_Create (from Activity_Resume it's the same) of an Activity started by the Main.

I can not test the app on a device with that version of Android (of course, otherwise I would not have used an emulator ).

Can someone do it (maybe even on Android 8)?


Many thanks.

I tried again using a small test project (attached):

*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
** Activity (actchooseimage) Create, isFirst = true **
** Activity (actchooseimage) Resume **
** Activity (actchooseimage) Pause, UserClosed = false **
--------- beginning of crash

There is (Android) a class named DocumentsProvider but no MtpDocumentsProvider.

From a site:
Si sente ormai parlare da anni di MTP, ma molti magari non conoscono la differenza con altri sistemi simili e il perché si utilizza così spesso. MTP significa Multimedia Transfer Protocol ed è un protocollo che mette in comunicazione due dispositivi elettronici, solitamente un computer e un dispositivo portatile. Se ne parla spesso su Android perché da Android 4.0 Ice Cream Sandwich è diventato il protocollo standard per scambiare file con il proprio PC quando lo si collega via USB.


Obviously I'm not using a USB, since I'm using an emulator, and I'm not passing files from pc to "device".

However, on @Emme Developer's real devices it works (at least the test project); this should be enough.


Thank you
