It seems it complain about a missing
com.google.api.server.spi.EndpointsServlet servlet defined in the
web.xml... Maybe you did not add the dependency?
Can you see if
https://cloud.google.com/endpoints/docs/frameworks/java/migrating is
helping you, especially the Gradle section?
Cheers,
Ludo

Hello,
Thank you for your response. I would suggest you to follow the link
<https://cloud.google.com/support/docs/issue-trackers> to file a
Feature Request on the support for Android Studio so our Engineering
team can further investigate. However, there is no ETA or if the
feature will be implemented.
For the deployment issue, based on the provided information, it would
be helpful to review the ‘appengine-web.xml’ to make sure all the
configuration is correct, especially the configuration about how Jetty
is started.

Hi Manpreet,
Thank you for your response. We already know that GCP does not
support Android Studio. But why? If GCP wants to compete with
AWS, Azure, Oracle, etc. it needs to move in the direction of
providing more cenvenience, not move away from convenience...
Any way, we contacted Google Cloud Platform Support at
<cloud-proactive-comms+...@google.com> but we didn't receive any
responses.
We're following this documentation:
https://cloud.google.com/appengine/docs/standard/java/sdk-gcloud-migration#migrate_config_script
Our Java Android app-engine project uses gradle and datanucleus.
(It doesn't use Maven build tool as there's no pom.xml file in our
entire project.) We have already created the cron.yaml and
index.yaml files and they work correctly from within Android Studio.

As listed on the “Migrating to the Cloud SDK-based Gradle
plugin
<https://cloud.google.com/appengine/docs/standard/java/tools/migrate-gradle#notable_differences>”
document, Android Studio is not supported. In order to run and
deploy your applications, you need to directly invoke Gradle.
Can you please shed light as to how you contacted the App
Engine Support in the past (Google Groups, Support Plan, other
community channels, ect...)? Can you also please share any
documentation that you are following? The documents will allow
us and the community to see how you are doing the migration
and why it isn’t successfully deploying.

before? Any way, when we try to deploy this app-engine
project by running the command:
>gcloud app deploy .\appengine-web.xml --version 3
--no-promote
The application fails to start with this error in the

BTW, we noticed that the size of the service which was
deployed via the gcloud command (5.4 MB) is much smaller
than the version deployed via Android Studio (38 MB).
This Java app-engine project is using gradle and datanucleus.
We have already contacted Google App Engine support couple
times, but no responses yet. Guess they're super busy with
all the issues that this botched migration has brought
with itself... What should we do now?
