Why am I required to do manually when before I didn't need to?

Hello!

2 months or so ago I had managed to setup appium + UIAutomator2. I just needed to install the driver (via NPM) and everything magically worked.

Today, I spent a few hours trying to understand why I kept getting the following error:

[debug] [Instrumentation] INSTRUMENTATION_STATUS: Error=Unable to find instrumentation info for: ComponentInfo{io.appium.uiautomator2.server.test/androidx.test.runner.AndroidJUnitRunner}
[debug] [Instrumentation] INSTRUMENTATION_STATUS: id=ActivityManagerService

[debug] [Instrumentation] 	at com.android.internal.os.RuntimeInit.main(RuntimeInit.java:355)
[debug] [Instrumentation] The process has exited with code 1

I managed to fix it by downloading this repository and following its steps (gradle clean assemble + manually install the 2 apks).

My question is: why is this now required for the automation to work when before all was nice and easy?

Also, I was planning to use appium and Browserstack but if I wouldn't be able to install the 2 apks manually every time. So, I must find a better solution.

Is this a bug somewhere else or is the new "workflow"?

It is not required, no.

It's not clear that there is a bug. Make sure you have the latest version of Appium 2 and then try this with your device connected to clear everything out and upgrade the driver to the latest version:

appium driver run uiautomator2 reset
appium driver update uiautomator2

Hello @jlipps,

Thanks for the reply.

Here is the output of those commands:

ok, try the latest uiautomator2 driver. it was not correctly exporting the reset script before.
