Command Used

adb -s emulator-5554 shell getevent | ./adb-event-mirror.main.kts emulator-5556 --debug

Can you run adb -s emulator-5556 shell getevent -p and paste that output? It contains the input device mapping on the second emulator. Right now touch is being mapped to input10 but that doesn't appear to be the right device.

EDIT: Sorry, I did close the emulators, and just reopened them to get this data. Do I need to run the ./adb-event-mirror.main.kts command again with --debug?

Ah okay it's a logic problem. Thanks. Will fix tomorrow.

Sounds great! Thanks 👍

And in case I'm dumb and don't spot the problem again tomorrow:

The problem is we're comparing "event10" and "event8" lexicographically which means "event10" incorrectly sorts lower than "event8" but we want the lowest numeric value, not which sorts lowest in string form.

Ok I have the fix, but I'm going to try to land testing first so I can script up a bunch of test cases to prevent regression.

I retried the script with latest update, however I still have same result as before. Sorry, if you are in the process of releasing new version with additional instruction that I may have missed.

Here is my AVD list

➜  adb-event-mirror git:(trunk) emulator -list-avds
Android_TV_1080p_API_28
Android_TV_1080p_API_Q
Nexus_4_API_25_Slow
Nexus_5X_API_25
Nexus_5_API_23
Nexus_5_API_25_Slow_Network
Nexus_5_API_29
Nexus_9_API_25

Pixel_3_API_30 <<------------ emulator-5554
Pixel_3_API_30_Mirror <<----- emulator-5556
Pixel_3_XL_API_R
Pixel_API_25

Here are relevant logs taken with latest update

Let me know if there are some changes in command that should be used to execute. Thanks 🙏

Out of curiosity I created another set of emulators. I already had Nexus_5_API_23 so I created Nexus_5_API_23_Mirror and it worked. ✅

I am not sure what is wrong with Pixel_3_API_30* emulators. Is it the position?

Here is my updated AVD list.

➜  adb-event-mirror git:(trunk) emulator -list-avds                                                                    
Android_TV_1080p_API_28
Android_TV_1080p_API_Q
Nexus_4_API_25_Slow
Nexus_5X_API_25
Nexus_5_API_23
Nexus_5_API_23_Mirror
Nexus_5_API_25_Slow_Network
Nexus_5_API_29
Nexus_9_API_25
Pixel_2_API_29
Pixel_2_XL_API_29
Pixel_3_API_30
Pixel_3_API_30_Mirror
Pixel_3_XL_API_R
Pixel_API_25

UPDATE: I have created another set of emulators Pixel_2_XL_API_30*, but this time without google play store. And it worked (even though bit slow on drags).

So, I am guessing, something is happening with "Google Play" emulators.
