Android Question Confused - External Storage

[Robert Valentino]

I have been ALWAYS able to look at and read files from a SD Card using a function cFilePicker that I put up here (my Music Program reads the MP3 files on the SD Card).

I haven't tried any writes. Just reads and copies


Do I only need the external storage access to write?

NOTES: I am using a true Micro SD Card for my tests - Most of my devices are Samsung (if that is a factor)

Yes, sure.

You need the class to get access at all.

Strange that I have been able to read without it. All my Samsung devices and even my Honda Ridgeline car stereo (Android 4.2.2)

Will make the changes and see what happens.

Thanks.

It depends on the targetsdk used

At doctor's right now, but believe I am using 5 and 29

If they are all Android 4.2 then it works. Starting from Android 6 you need to use Runtimepermissions and starting from Android 10 you´ll get no access to the external storage without using StorageAccessClass.

GR8, currently all my devices are Android 8.0 and less. But will start the change over ASAP.
Thanks
