Answer 1

I had a similar problem with another program. The problem was that another screen sharing program on my machine was opening an old ADB server, which leads to miscommunication between the program and the phone.

Answer 2

I had this problem when ADB was not authorized to access the device.
If Android Studio can initialize ADB without a device connected to your computer, then the problem is probably related to this issue.

To fix this, I started the adb server from the terminal, authorized it and the restarted Android Studio.

Answer 3

In android studio, File -> Project Structure -> Module -> Your projectname_android-> dependencies->modules sdk: (select api as android api platform), then click Apply and OK.

And do which adb output in my case /usr/local/bin/adb ls -la /usr/local/bin/adb

/usr/local/bin/adb -> <path to correct adb location which is mentioned in sdk in android studio.

After doing these steps issue was resolved.
