Hello there @Sumitbera!
The build URL You sent us is a different build I think for this is a time out on a custom step called bitrise-step-update-jira-issue-field
but for the testing issue I would recommend this tutorial on the Virtual Device Test for Android tutorial of ours.
https://devcenter.bitrise.io/testing/device-testing-for-android/
as far as experience goes, this practice is much more reliable than avd manager.
