How to rectify the errors in the autogenerated IMarketBillingService.java file?

Question

I am trying to implement In app billing service in my Andorid application.

I\'ve added the IMarketBillingService.aidl file to my project in

Answer 1

Project-->clean and build may solve it as well

Answer 2

You might try to use default compile options.

1. Right-click (or Control-Click) the project and select "Properties"
2. Select "Java Compiler"
3. Uncheck "Enable Project Specific Settings"

Eclipse will prompt to re-compile and it should be all good.

Answer 3

Was also getting numerous errors in the generated IInAppBillingService.java. I tried many, many suggested solutions without success. Finally a variant of Zedifire's method worked on my Eclipse SDK. (these steps are from memory - try around until it works!)

1. turned off >Project>Build Automatically
2. deleted the /gen files
3. THEN went to >Window>Preferences>Java>Compiler and found that somehow compliance level had defaulted to 1.5
4. changed compliance back to level 1.7
5. >Project>Clean
6. >Project>Build All (still errors!)
7. Right clicked on project window >android tools>fix project properties

VOILA -the generated files finally compiled without the errors!

The reason is, that Java 1.5 does not support overriding interface methods. https://stackoverflow.com/a/212642/1283492 From Java 1.6 onwards it is allowed. Thus as already stated by easycheese, one needs to put Java 1.6 or higher in the java compiler settings of the project properties.
