how to stop react native automatically starting the emulator and not connecting to my smartphone-CodePudding

So, after testing my app on my emulator I tried to run it on my device on my phone. I have enabled the developer option with USB debugging.

whenever I type npm run android it automatically starts my emulator, even when my actual device is connected to my PC.

It would be really nice if someone point out what could be the issue.

ps. It was working fine before i started the project.

CodePudding user response：

You have to check that the device is properly connected with the PC or not.

Just run a command adb devices in terminal.

If the device is connected then it will be listed there.

Specify a simulator using the --simulator flag.
