Android12 emulator fails due to 'Error retrieving device density'

[sleekweasel]

Describe the bug

bundletool 1.8.0 doesn't seem to work with Android 12 emulator.

Bundletool version(s) affected
Version: 1.8.0 (downloaded from https://github.com/google/bundletool/releases)

Stacktrace
$ java -jar Downloads/bundletool-all-1.8.0.jar get-device-spec --device-id emulator-5554 --output foo.json
[BT:1.8.0] Error: Error retrieving device density. Please try again.
java.lang.IllegalStateException: Error retrieving device density. Please try again.

To Reproduce
Steps to reproduce the behavior.

1. Download Android 12 (Google APIs, not playstore) and use Android Studio to create default emulator
2. Run java -jar Downloads/bundletool-all-1.8.0.jar get-device-spec --device-id emulator-5554 --output foo.json
3. It complains about retrieving density.
4. Same thing happens when trying to install an APKS file, but get-device-spec is simpler to report.

Expected behavior

It retrieves density.

Known workaround

Nope.

Environment:
OS: Linux timblenovo 5.4.0-81-generic #91~18.04.1-Ubuntu SMP Fri Jul 23 13:36:29 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
$ adb version
Android Debug Bridge version 1.0.41
Version 31.0.3-7562133
Installed as /home/tim/Android/Sdk/platform-tools/adb

Additional context

I've reproduced similar behaviour on our test system (with a rather older version of bundletool, and with the 1.8.0 version) and my colleague has independently reproduced it on her machine.

Incidentally, where are the latest sources for ddmlib, and is there a way to contribute patches to it if we find the problem?

Thanks.

Android12 lacks the device density property. Reported here:
