Android Question FTP Server implemented

[jcmartini]

I tried to use the example given in:

https://www.b4x.com/android/forum/t...mplemented-with-socket-and-asyncstreams.74320

For me it does not work. Connection seems to be ok with a windows client (Winscp), but the the list of files and directories cannot be done with the following message:
"Unknown command: PORT".
I also changed in the manifest file the targetSdkVersion to 33. I don't know of this error is coming from my change. Is somebody has an idea on how to correct this example ?

Moved to the questions forum.

Looks like you are connecting in active mode instead of passive mode. Change your client configuration.

Thanks, it works... Except that I only see the directories of the phone, not any file. For example "Camera/DCIM" is empty. What Did I wrong ?

your app do not have direct access to this folders if you are using a higher targetsdk

What do you mean ? I tried it with sdk 29, it does not list anay directory. In sdk 30, it list only directories, not any file. Which version should I use ?

If this is a non-Google Play app then you can set targetSdkVersion to 28 and request the external storage permission at runtime.

android.jar / targetSdkVersion / minSdkVersion

There are several versioned components that affect the compilation process and the runtime behavior of our apps. The purpose of this tutorial is to explain the differences between them and help you choose which version to use. Each Android version is mapped to an api level. You can see this...
