Android Question Cannot detect USB stick on Raspberry Pi3

[prokli]

Running the code shown next on my tablet (Android 9) the code works perfectly.
After calling the function "hdd" keeps memory- and USB stick storage location

Dim hdd As List
Dim rp1 As RuntimePermissions

Sub GetExtMemory()
hdd = rp1.GetAllSafeDirsExternal("")  

End Sub

But running this code on Raspberry I just get the memory location (SD card)
OS is "LineageOS 16". May be this is an issue of this certain OS and does not depend of any permission?!
I don't know.

Try with ExternalStorage.

I tried to implement ExternalStoarge as demonstated here:

Entire example fails on RPi3

Entire example fails on RPi3

This is not a useful statement. We cannot help you based on this information.

Okay, let me try to explain!
I compiled and installed next program to the RPi3:
https://www.b4x.com/android/forum/t...access-sd-cards-and-usb-sticks.90238/#content
When I start the "ExternalStorage" app I get the picture shown next. Clicking on "Pick folder" opens the browser app which is provided by LineagOS as default app.
Nothing else happens

Can you choose a folder with this app?

 

[prokli]

No, Erel! This is not possible. Does the device need root permission??

 

[Erel]

It is not related to root permission. I guess that this feature is not implemented properly on the RPi3.

Try to find the file path yourself and access it directly. It will not work on regular Android devices but might work here.
