I accidentally exited out of the popup where app inventor asked for the path to adb

How can I get it back again so I can put the 开发者_如何学运维right path into it? I think this is the reason that app inventor wont connect to my phone.

If you lost the location, the instructions at Install the App Inventor Extras Software in http://appinventor.googlelabs.com/learn/setup/ should help. The locations may be changed a bit, the dev team just updated the installer.

Check out Jason's Troubleshooting ADB Path http://android.jwtyler.com/Tutorials.html

It covers resetting the path.

This conversation has a better way to get the path set on Windows http://appinventor.googlelabs.com/forum/#topic/getting-started-with-app-inventor/dRiJXp5kyBA/discussion

and this covers Linux http://appinventor.googlelabs.com/forum/#topic/getting-started-with-app-inventor/vSP0UyBvDog/discussion

You have to exit the block editor, and then restart it. (At least for me that was the only option.)

Also, the fact that my system couldn't find ADB was because I didn't have it installed!! Once I installed ADB, the pop up didn't show up.
