Android Studio 看不到所有设备

Question

a few days ago there was no problem when I used my device to run the application. but suddenly when I plug the usb into my device android studio displays no device and I try to replace another device but still not detected in android studio even though in the file explorer device is detected. I tried using the same device and same usb on another laptop and it was detected. I've tried several answers like install adb but it still didn't work

Answer 1

Could you tap adb devices on your cmd and check if you see your plugged devices.

If not please check if u correctly check the developer options "Enable USB debugging" from your device.

Answer 2

Please check:

• Developer mode is on;

• USB debugging: enable;

• Verify apps over USB is off;

• only charging this device via USB - is off;

• switch USB computer connection to PTP mode or to File Transfer mode;

• ensure that you are applyed fingerprinting keys in popup window after connection new device to your computer;

• your USB-cable is real Data-Cable (not only for charging);

Answer 3

您的ADB drivers与您的设备不兼容，您需要安装Universal ADB drivers或尝试open google ADB drivers （某些电话公司不支持 google ADB 驱动程序）。
