Cheers, Lia.- Hide quoted text - - Show quoted text - My application relies on dynamic loading of classes using PathClassLoader as well. My main concern is the permissions that are going to be set on /data/ dalvic-cache in a target device, such as the new HTC G1 phone. If the permissions are the same as in the emulator, very high chance that users will not be able to shell in an issue chmod 777 commands (can't expect users to perform such tasks either). This would render our application inoperable. I am going to do some more research, try and find out what the permissions on the /data/dalvic-cache in HTC G1 will be. If I find out any info, I'll post it in this blog. Cheers, MoggoDude --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

Thanks Lia, it seems to be working. Is this a bug in the SDK or intentionally?
