[android-developers] Re: How to access a AIDL service from different packages?

Hi Priyank,

Problem belong this step:
>I have exported this in the source code of the application as
>import com.VMService;

you don't need to do this step because because aidl generate Java interface, refer: http://developer.android.com/tools/building/index.html

i guest your error come because class com.VMService not available during runtime,
although in compile and packaging time is OK because it using difference class
(I not sure about order in compile time and runtime)

Best Regards,

Hi,
I am kind of facing a similar problem with my project.
I have an existing project which has 2 parts. Services module and
Application module.
The VMService.aidl file is in a package in the services. When the
service module is compiled, the generated VMService.java file appears
in the /gen folder.

I have exported this in the source code of the application as
import com.VMService;

But I am still getting run time errors during the launch of the
application.
The LogCat logs show this:
Could not find class com.VMService
06-30 17:33:11.248: ERROR/dalvikvm(460): Could not find class
'com.VVMService', referenced from method
com.samsung.vvmapp.VMApplication.onActivityResult

06-30 17:33:11.457: ERROR/AndroidRuntime(460):
java.lang.NoClassDefFoundError: com.VMService

Please let me know what wrong I am doing.
Thanks,
Priyank
