Android Spring Integration

I am facing an issue while trying to use the spring android framework. I have tried the samples according to this link. Actually I can't get it to work. Because when I try to import the spring-android-rest-template-1.0.0.M1.jar and spring-android-commons-logging-1.0.0.M1.jar it gives an error saying

Conversion to Dalvik format failed with error 1

Therefore I was not able to complete the sample program.

I have downloaded the the jar files separately. It gives no开发者_StackOverflow errors in the code. But a top level error is generating.

Why is this error occurring, has anyone else got the same issue ?

I was getting the same error too, used the solution noted here: "Conversion to Dalvik format failed with error 1" on external JAR removing all libraries from build path, clean and rebuild, then adding just the spring-android-rest-template-1.0.0.BUILD-SNAPSHOT.jar
