[protobuf] Re: NoClassDefFoundError Android
SOLVED! The problem was not a protocol buffers problem, however a more general problem in ADT after updating. The jars was not copied to the device. For people experincing the same, have a look at: http://stackoverflow.com/questions/1334802/how-can-i-use-external-jars-in-an-android-project http://stackoverflow.com/questions/2247998/noclassdeffounderror-eclipse-and-android Best and thanks Kasper Revsbech Den tirsdag den 8. maj 2012 09.25.37 UTC+2 skrev Kasper Revsbech: Hi all I have a mind wrapping problem using protocol Buffers on Android. I among other commands defined a request in my .proto file: http://pastebin.com/B4htQeRm In my communication I do as follows: Protocol.request.Builder r = Protocol.request.newBuilder(); However on run time I get the error: java.lang.NoClassDefFoundError dk.revsbech.client.Protocol$request I have now trie with at bunch of jar files both pre compiled and manually compiled both with and withouut Maven, both with and without the LITE_RUNTIME optimization.

[protobuf] Re: NoClassDefFoundError
Just another case of RTFM^^ Thank you very much for the help. Jubei ps. Btw isn't it strange to have to use source from a tarball to compile a compiler (protoc) which one must then use to compile more source from that same tarball? Is it OS related?

[protobuf] Re: NoClassDefFoundError
Thank you for your response. Unfortunately I'm not sure what descriptor.proto is. I never had to compile that before. What would I do with the output of compiling that file?
