Android设备无法连接到本地主机

Question

I am developing an app for Android. I have been happily developing it for a while, connecting the phone to the PC using a USB, using 192.168.xx as the address the code points to log in, etc.

I started my IDE a couple of hours before, and without changing a single comma anywhere, I receive an Exception:

• I have checked the server is up
• My phone is connected to the same wifi the PC with the server is
• Internet permission is in my manifest
• I do have Internet, since I am writing this here
• My phone has Internet, since I have been accessing the internet with him, via the same WiFi
• Did ipconfig to make sure the IP is correct

i am getting mad... any help? Thank you!

A very weird thing happened. When I did ipconfig I would swear over the most sacred thing on earth i saw 192.168.1.4. I did it more than one time, always saying 192.168.1.4. After posting this question I did it again...and it showed 192.168.1.3. i changed it in the Android app and now i am able to access server.

Is there some time between an IP has changed and the ipconfig shows it? Because im SURE it said 192.168.1.4 the first 3 times I did it...
