My project was working fine until I exported it and installed it on my android phone.  
The previewer did its part correctly, but the exported app was not doing all the connection stuff…

What does the code do?  
Are you making a connection with another device?  
If so did you give the “CHANGE WIFI MULTICAST STATE” permission?

@Why_I_Use_Processing ===

- Can you explain better what you have done?
- Technical infos about the os running on your phone? Are you using APDE or P5?
- What do you mean by connection stuff?
- Put some relevant part of your code

Ok I solved the problem.  
I was using APDE for your information on my android phone and I just forgot ask for network access permission that was already given to the APDE’s sketch preview but not to the exported app…
