Hi! I have a code working at all. It runs everything and finds sketch’s data. The only error is a deprecated method, but it is underlined yellow, then I think it should not affect.
It says Sketch launched on the device, but on my phone it appears a fast flash and then a black screen when the app is opened.
Thank you very much

sure about your permissions???
Hi @akenaton. I’m not sure about permissions. I know I accepted them when installing Android sdk, but should I check them elsewhere? Thank you.

i asked that because normally this kind of “flash” is resulting from the permissions which were not asked on runtime: the os try to open its permission window but very fastly closes…
