Why I have Android ADB offline status when connect Android device with USB debugging mode? It can detect my Android 4.2.2 Jelly Bean device but have offline status. Fear no more, there is a solution to fix this issue. Just update Android SDK Development Environment (Android SDK Tools and Android SDK Platform-tools) with Android SDK Manager to the latest version. That’s should fix it. And don’t forget to allow USB debugging access from your computer then.
