Hi,

I've been trying to run screenshot tests on Firebase test lab however i am running into this error:

Someone had similar issue before based on this thread. The solution mentioned in that thread by @xiphirx is to run these commands: adb shell settings put global hidden_api_policy_p_apps 1 adb shell settings put global hidden_api_policy_pre_p_apps 1 adb shell settings put global hidden_api_policy 1 // this is for Q+

However, i don't have access to adb on firebase. Was anyone able to bypass this issue and get screenshot tests working on Firebase Test Lab?

I think this problem occurs for API >=28 because when i test it with Galaxy S7 edge, API Level 23 on Firebase Test Lab, it works.

Yeah this is because of restrictions on hidden API access / reflection. Unfortunately I don't have much of a solution for you outside of those adb commands :(

I think at some point it would make sense to re-evaluate and see if all of the reflection is necessary in the library.
