Android Question Error FilePicker

[Israel Gallegos]

Hi! I Am using Filepicker on my project, based in this library
https://www.b4x.com/android/forum/threads/filepicker-with-pickvisualmedia-in-android-13.149217/

I added the JAVA code included in the example.
I added the additional libraries included in the example.

My Android Version is 14 (Tablet)
TargetSDK: 33

But I get the following Error

Any idea?

This java code has not any problem. don't know how you are using the code in your project.

 

[Erel]

You should use ContentChooser. See this example: [B4X] TextEditor - Save and load external files
