1806204 - Android gtest run spends 7 minutes hanging before starting to run the tests

Status: NEW

(Testing :: GTest, defect, P3)

Description

[Botond Ballo [:botond]]

Attachment: Output of `mach gtest`

Steps to run

1. Do an Android device (armv7) build of mozilla-central
2. Run ./mach gtest <testname>, for example ./mach gtest APZEventResultTester.ScrollableDirections

Actual results

The test run hangs for about ~7 minutes before starting to run the tests.

I attached the complete output, but see in particular the following lines that show the 7-minute hang:

 1:08.80 adb INFO Setting run_as_package to org.mozilla.geckoview.test_runner
gtest INFO | Running Android gtest
 8:03.97 adb INFO Granting important runtime permissions to org.mozilla.geckoview.test_runner

Expected results

The test starts running more quickly.

Doesn't seem to happen in an emulator build, the interval between those two log messages is more like ~40 seconds there which seems more reasonable.

Attachment: `adb logcat` during the period of the hang

Also attaching the contents of adb logcat during the period of the hang (around 18:29 to 18:36 in the timestamps).
