适用于Android的CoAP示例

Question

I'm trying to build a CoAP server in android, and i's using californium's example.

https://github.com/curioustechizen/Californium/tree/4ace5b85974a0646aaaa6ab43c9314d1c5a438e1

But I got error with Http.java in package ch.ethz.inf.vs.californium.layers

it shows

The type org.apache.http.entity.ContentType  cannot be resolved. It is indirectly referenced from required .class files

I'm thinking the problem is about the wrong .jar file the library I imported is like this:

apache-mimne4j.core-0.7.2.jar californium-0.18.7-final.jar commons-codec-1.6.jar commons-io-2.4.jar commons-logging-1.1.1.jar google-http-client-1.10.3-beta.jar google-oauth-client-1.10.1-beta.jar gson-2.1.jar guava-11.0.1.jar httpclient-4.2.1.jar httpclient-4.3.2.jar httpcore-nio-4.2.1.jar jsr305-1.3.9.jar junit-3.8.1.jar junit-4.8.1.jar mockito-core-1.8.5.jar

hope anyone can tell me whats the problem or how to fix it, and also ask to some open source about CoAP's android example.

Answer 1

I think you are missing a http-components jar there. Do you use maven?

Please note: your fork is too old (2 years). You can find the actual Californium version at https://eclipse.org/californium/ It does not have android support but I see your fork only removes a lot of files and adds an android manifest at most - so it could be done too.
