404 Error starting TicTacToe (Android) sample against Google App Engine (Java) sample project

Question

I installed the backend of the Android application and the Google App Engine, as shown in these two projects:

• Android Engine Engine>
• Java App Engine Backend Project

When I click on the TicTacToe field button that launches the request, I get 404 error: "Not found"

04-09 23:11:51.115: W/TicTacToe(26247): GetComputerMoveTask: 404 Not Found 04-09 23:11:51.115: W/TicTacToe(26247): Not Found 

This is exactly what https: // myappname .appspot.com / _ah / api / shows "Not Found" in the browser.

Here is what I did:

• Created an api project on the App Engine console
• An Android client id was created there with com.google.devrel.samples.ttt as a package that contains my SHA1-fingerprint debugging keys
• Web Client ID Created
• Integrated Android project in eclipse. Updated DEFAULT_ROOT_URL in Tictactoe.java to "https: // myappname .appspot.com / _ah / api /"
• Updated AUDIENCE value in ClientCredentials.java, replacing the string "your_web_client_id" with the generated web client-id from step 3
• Integrated the backend project in Java in eclipse. Updated app value in appengine-web.xml for myappname
• Updated values ​​in /spi/Ids.java to display web client id and android-client-id from step 2 and 3
• Updated google.devrel.samples.ttt.CLIENT_ID value in war / js / render with web client id
• The backend for google is deployed. Works great - it opens https: // myappname .appspot.com / page that displays the correct page after deployment (servlet)
• An Android application has been deployed and tried to take a step in TicTacToe. The application crashes.

I think his very suspicious my DEFAULT_ROOT_URL is set to "https: // myappname .appspot.com / _ah / api /" in my Android application, whereas on these pages only "Not Found" is displayed in the browser.

What's going on here?

Thanks in advance

Answer 1

Try testing your API at https://your_app_id.appspot.com/_ah/api/tictactoe/v1/ and see if it does what you want.

Research this link: https://github.com/GoogleCloudPlatform/appengine-endpoints-tictactoe-android/blob/master/app/src/main/java/com/google/api/services/tictactoe/Tictactoe.java

Lines 60-74

https://github.com/GoogleCloudPlatform/appengine-endpoints-tictactoe-java/blob/master/src/com/google/devrel/samples/ttt/spi/BoardV1.java

Lines 29-31

I suspect you have the wrong API URL, and diving into the code seems obvious that the above URL is correct.

Answer 2

I don’t know where you get the instructions for step 4 (in your list), but see the Installation Instructions in the Android project, step 2, what you need to do:

Update the DEFAULT_ROOT_URL value in src/com/appspot/api/services/tictactoe/Tictactoe.java to indicate where you are using the Tic Tac Toe backend (based on the Java backend example).

And the place in your case is "https: // myappname .appspot.com /".
