These steps are so annoying and error-prone, I am creating a documentation for myself, should I have to deal with this piece of shit ever again.

Enable Developer Mode

Go to Settings / About Device / Version and tap Build number 10 times.

Go to Settings / System Settings / Developer options and make sure USB debugging is turned on.

Plugging your phone in

Plug in your phone. MAKE SURE TO SELECT USB FILE TRANSFER / ANDROID AUTO and not just “USB charging”, otherwise the developer tools won’t connect.

A popup should appear, select “always accept”.

Run this from your terminal:

$ adb devices
List of devices attached
47d81c93  device

Running your app from Android Studio

Now the “OnePlus IN2023” device should appear in the list of Running Devices in your Android Studio. You should be able to run your app now.

Workarounds

Previously there was a need to specify proper udev permissions in order for adb to access your device. That should no longer be necessary. Still, if adb is saying no permissions, make sure that:

• Your user is in the plugdev group, by running groups in terminal
• Locate your phone via lsusb, then create an udev rule:

$ sudo vi /etc/udev/rules.d/51-android.rules
SUBSYSTEM=="usb", ATTR{idVendor}=="22b8", ATTR{idProduct}=="2e81", MODE="0666", GROUP="plugdev"

$ sudo udevadm control --reload-rules
