I have taken the easy way, I have joined the two extensions.
Now the extension is called com.KIO4_Pdf.aix, if you use the blocks that end in 10 (Create10, AddPage10 and Finish10) the files will be created in ASD, these blocks are appropriate to Android> = 10.

Using the GetApi block, you can get the Android version of the device.
You can download the extension from:
