Today, I updated my Android SDK and Eciple ADT to the most recent versions (ADT Rev 22). After restarting Eclipse it is quite unhappy with the Build Paths whenever I reference custom libraries.
An example is shown in this screenshot:
My custom "Android Utilities Library" compiles fine, but everything that depends on it shows build path errors. E.g. when I investigate the build path settings for "Android URA Library" it shows me an error with the android_utilities_library.jar missing under "Android Dependencies" (which in fact is true, the libraries will be built to individual class files in bin/classes).
After reading the solution to Build path errors with library projects I tried to clean and manually build my projects in the correct order, but to no avail.
I've never dealt with this before, so I don't know how to attack the problem.
Any help is appreciated. Thx!
Installing the new Build Tools did the trick. They were not automatically included when I updated the SDK (probably need to run the update twice I guess).
I found a solution that works for me: Go to Project Properties > Build Path > Order and Export
Then you have to check each checkbox. In my case my libraries were restored
I hope it will help.
I can see that your project Android URA Library is referring to Android Utilities Library, then the problem should not relate to SDK/ADT update.
Please check:
- Project Properties of
Android URA Library, choose Project tab and make sure you addedAndroid Utilities Libraryas dependency project. Otherwise, please add it. - If the problem is still existing, then Projects \ Clean All Projects
Go to libraries and check the build path of the dependent libraries. It should be same as your projects build path.
if you have import all the Dependencies in your workSpace.maybe you can:projetc-->build all. I meet the problem,and it works well
