Google App Engine Java SDK (1.7.5 or newer) Java 7 Apache MavenYou need to be familiar with development using Google App Engine and the Java runtime. 14. Create your backend API project (using Maven to do this is the easiest method), then write your API backend code. Annotate your API backend code, so classes and client libraries can be generated from it. (Alternatively, use the Google Plugin for Eclipse, which can annotate for you.) Generate the client library using Maven, or alternatively, the endpoints.sh command line tool. (Another alternative is to use the Google Plugin for Eclipse to generate the client library.) Write your client app, using the client library when making calls to the API backend. 15. 16. 17. API 18. API insert list nyaaby 19.
