Can't connect LG G3 to Android Studio
As on Android 6.0 device & Windows 10 this worked for me. Steps 1 & 2 before attaching phone to computer.
1) Activate developers settings (Settings -> General -> About phone -> Software info -> Press 7 times "Build number" button). After that it says "Now you are an developer".
2) Go back to General settings and press "Developer options". After that find option "USB debugging" and tick that box.USB debugging
3) Attach phone to the computer via USB. Phone will ask "Allow this computer to access your phone data" "Allow". After that you should have "Tap for more USB options" -notification. Choose "Send images (PTP)"
Create "Hello World" -project as an test and try to to select deployment target again.
Make sure you enable developer options on your phone and check 'Enable USB Debugging'
On your Phone... Go to your settings: Go to "about phone" Tap on "Build Number" 7 times. This enables developer options Go to Developer options (in the settings app) Check - Enable USB DebuggingDid you make sure to install the adb drivers for your phone? Also make sure you have enabled debug mode on your device. If neither of those are the issue, maybe check here for further troubleshooting help.
When you connect your phone to your computer with Android studio running, you should see a dialog box asking for permission for your computer to debug your phone. Tap Yes and accept those permissions.
You should be set from there! Hit 'Run' in Android Studio and you should be good to go.
