Android Question Detect SD card with (File.ExternalWritable = True) does not seem to work

MitchBu · Jul 1, 2019

I want to show a button only if an SD card is present, so I do:

B4X:

BtnRegisterOpen.Visible = (File.ExternalWritable = True)

Unfortunately, the button stays visible, although I removed the SD card.

Did I miss something ?

Thank you.

The "external storage" is actually internal on 99% of the devices.

You can use RuntimePermissions.GetAllSafeDirsExternal to find your app specific folder on the sd card (if one is available).

See this for more information: ExternalStorage - Access SD cards and USB sticks

That works great.

Thank you Erel
