The "-logcat-output {file}" argument for the android emulator does not currently output logs to the file, possibly due to the emulator shutting down in the wrong way or some other error with the argument.

see e.g.: http://10.212.0.130/coin/integration/qt/qt5/tasks/1702793575_restarted in the successful android-14 testcase run, in downloads/testresults.tar.gz, the emulator_logcat_1.txt file is completely empty.
