Google App Engine Cloud Endpoints Pr@blem Marker - > Generate App Engine Error on clean Android Project

Question

I created a clean Android Application A then I right clicked on it and selected Google->Generate App Engine That caused this:

and the error description is that:

Description Resource    Path    Location    Type
There was a problem generating the API metadata for your Cloud Endpoints classes: com.google.api.server.spi.tools.ClientLibGenerator$Language   A-AppEngine     Unknown Google App Engine Cloud Endpoints Problem Marker

How to fix this?

Answer 1

After checking out a lot of posts I finally fixed this error, though I have no clue why it is happening:

• Right click on the project
• Properties-->Builders
• Uncheck the Google App Engine Project Validator.
• Then clean the project.
• Then check the Google App Engine Project Validator again.
• Then left click the project,
• Go to Project-->Build Project.
• Done.

Anyone can explain this?

Answer 2

The true answer is: Download older App Engine 1.93 even if you should 1.94.

Answer 3

I had this problem a while back with an android app and the accepted solution worked.

Right now I have the same problem with a GWT/GAE app. (GAE 1.9.9)

The only way I can stop it is revert to a backup. On replacing the (irrelelevant) code changes the problem has not so far not reappeared.
