Unable to connect to my android device via ADB

Question

Sorry for the nooby question, I am having trouble sorting this out using the web.

I am trying to simply connect my device to my pc via adb to debug my application.

My device is rooted. Adb debugging is enabled. I downloaded an adb running application and started ADB.

Now i am trying adb connect ip:5555. and keep on getting "unable to connect to ip:5555" ...

Same happend when i try to connect via usb.

c:\>adb connect 192.168.20.191:5555
unable to connect to 192.168.20.191:5555

Help...?

EDIT: C:>adb devices List of devices attached 06fecaa1 unauthorized

Answer 1

Launching Cordova

1. Open Node.js / CMD
2. Point to "the directory where you have located your source folder" >>> C:\Projects\RJX
3. Enable Wifi
4. Turn on Developer Option under settings
5. Enable / Check USB Debugging Option under settings (Google if cannot find this option)
6. Enable / Check the MTP Option under settings (Google if cannot find this option)

ADB Commands

adb kill-server
adb start-server
//plug off cable from mobile and plug in again if you connected your device earlier
//Uninstall the application from mobile if you already installed. (if necessary)
adb tcpip 5555
adb connect "ip" //adb connect 192.192.2.128
adb devices //to check device details
cordova run android --device

if this steps are not worked, try to close the cmd and do it again. Sometimes it needs some refresh. **Android devices version 4.0.4 and after should be no problem if you follow these steps.

I will assume you are able to understand adb connect / ip's etc I won't bore you with that

but there are two lame "gotcha's"

THE GENYMOTION GOTCHA

genymotion WRECKS a lot of this sometimes.. I am sorry but it does.. it has a "I know what I am doing I am taking over" mentality.. sadly it doesn't know what it's doing :-P often you have to turn off genymotion for the adb->usb to work.. basically connect phone FIRST ... make sure it's there in eclipse (adb kill-server / start server if needs be ), then AND ONLY THEN then genymotion AFTER

THE OOPS [/facepalm] GOTCHA

check that your phone it isn't in Windows merely as a "Camera" - go to My Computer and look. If it looks like this pic it's that you're not running Samsung Kies(/disabled because it's annoying) the phone still goes "blub bling" when you plug it in, it may be connected via wifi so have a LAN ip but it is NOT really "connected" to ur PC. instead run/download/update this (with phone disconnected) then make sure Kies is happy AND MAKE SURE MTU is enabled
