This means that you are still referencing an old version of the core library. Reinstall B4A in a new folder.

Hi Erel, thanks.. I am showing B4A to a friend.. I don´t understand.. is enough changing the directory??? Regards

 

[Erel]

Try to reinstall B4A in a different folder.

Thanks Ere, fantastic!!! I want that my friend will be a new user.. We've changed the folder and we dont´t have problems. It's running!!!
... now we have another problem.. we try to connect a motorola device (MOTO E, 4G LTE, android version 5.0.2), and in some case the device runs but in other case, we don´t get to contact. We have get to contact using b4bridge by means the IP but only in one ocasions. We have tried to repeat the proccess but we have not success. Using USB connection never we have success. The aplication does not generate error...

Have you enabled usb debug mode? Also make sure that the usb storage mode is set to PTP.

Hi,
Have you take a look if there are specific driver for Windows for your phone on the Manufacturer Website ?
Sometime the phones need a specific driver to be recognized, not all, but.
I have had already problem with some tablet.
