I have installed Bridge on my phone.
I have activated Wireless connection on it.
I have connected in B4A my phone with Tool-B4A Bridge-Connect
I have run my application in Debug(rapid) mode to test it.

It has worked fine until today.
Now, with the same process, instead of run apk installation on phone return this error:
libcore.io.ErrnoException: recvfrom failed: ECONNRESET (Connection reset by peer)
I noticed that B4A-bridge indicates "disconnected" for a few moments.

i already have:
- uninstalled app from phone
- cleaned phone (after uninstall) with CleanMaster
- used in B4A Tools-Clean project
- tryed to use other compiling mode (for example "Debug legacy")
- checked that wi-fi works properly
- restarted PC and phone too
With AVD works slowly but work

How can i solve this problem?
Thank you

You should enable USB debug mode, connect the device with a USB cable, install the device USB driver (Google your device model with ADB) and disconnect B4A-Bridge.

I do:
1. enable USB debug mode
2. connect the device with usb cable
3. install the device USB derive

but don't solved this problem:(

my problem solved with this work :
1. I uninstall the B4A from own computer then re install it.
2. when I install it and press F2 , I should install the B4A Designer in own device.

I have a question : why I should install B4A Designer ?
