I was running my app with vscode using Android emulator or my phone, however all of a sudden vscode could not identify any device or emulator that I connect (no devices). phone is in debug mode or even the android emulator. Also When I try starting the emulator I get this warning
Seems like adb
can't be found. Have you updated or moved the (Android) SDK recently?
You may want to check your platform-tools folder in your Android SDK and if necessary, download the tools again (see this answer).
