Question by Samuel014 · Aug 25, 2019 at 01:59 PM · errorandroid builderror buildandroid sdkadb

Build Project to Android Error: Unable to start ADB server.

Hello, When I try to build my Unity project to my android device, it gives the error: Unable to start ADB server. Please make sure the Android SDK is installed and is properly configured in the Editor. See the Console for more details. I have the Android SDK, NDK and JDK all set up. I have looked up for the error, but I really can't find a solution. I'm in Unity 2019.3.0a11, is it possible I have this error because I'm in an alpha version? Does anyone have a link with the steps to build Unity projects to Android? Or does anyone know how to fix this error?

Thanks in case

Around this same time, I also started getting this error. I installed Unity 2019.2.2 and everything was fine the first day. I went home and installed there on a new PC and it worked there. Came back to my office and this error started.

I tried upgrading today to 2019.2.3 and still receive the same error. I'm not sure if Windows is blocking the program or if it has something to do with Android Studio.

I can run ADB manually.

you are getting the same adb server error? i think that in 2019 there is a togle of "use unity sdk" or something like that (i have never used that version) in the prference window, untogle and go to the path where you know you have sdk installed, also i would try starting the server manually, using for example "adb start-server" in case you are getting the same error that should fix it and maybe give you a new one if something is wrong with your sdk, also some of the build tools versions dont work well with unity, the next step i would go is to install a version a bit older of that folder

For Oculus Quest builds you may need to close the Oculus Developer Hub or Sidequest (or both). This worked for me.
