[android-developers] Re: Access a Service across multiple Applications
Thanks a lot Mark! And sorry about the package thingy... Since the names were the same i thought they were the same packages. Making a new package with the SAME NAME as the AIDL was in in the previous application and copying the AIDL file in to that package solves the problem. Thanks again for the help. Cheers! Prafull.

You copy the AIDL file, put it in the same package as in the old project, and use it in your new project. In the links I provided earlier, you will see that the IScript AIDL file resides in both projects. > Here Mark has given some examples, but am not very clear as to how the > same interface will be used "across" applications.

They are two separate Android applications, with two separate APK files, two separate manifests, two separate source trees, and two separate copies of the same AIDL file in the same package. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 3.0 Available! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Access a Service across multiple Applications
Hi,
A li'l update since the last post, the problem regarding the
SecurityException is now resolved(i had to put intent-filters in the
manifest where the Service was defined) but now another problem
regarding the interface has risen. The interface (AIDL) for
communication between the activity and the service is defined in
another package in another application. How can i now access this SAME
interface for communicating with the service from my new application?
Any pointers? I searched through the forum and found this thread
http://groups.google.com/group/android-developers/browse_thread/thread/71ebbb00d6e2b67c/814f65ba19b5e33e?lnk=gst&q=unable+to+bind+to+a+service#814f65ba19b5e33e
Here Mark has given some examples, but am not very clear as to how the
same interface will be used "across" applications. The examples above
have the client in another package and the service in the other but
both packages in the SAME application. I also understand having access
to the service across applications the way i want poses a huge
security risk but we intend to build a very robust design to counter
those security threats.
Thanks,
Prafull.

[android-developers] Re: Access a Service across multiple Applications
Hi,
I have been trying out the same things that you mentioned in your
post. I've created a service from an application and on the
"onDestroy()" of that application i'm "unbinding" the service. Now
when i want to "bind" to the same service from another application, i
get a SecurityException. The actual error log is as below.
04-20 11:38:40.231: ERROR/AndroidRuntime(228): Caused by:
java.lang.SecurityException: Not allowed to bind to service Intent
{ cmp=aexp.dualservice/.DualService }

Is it because while defining my service i have given the package name
of that application and now when i'm trying to "bind" to the service
from another app. its giving me a SecurityException that i'm accessing
something from another package altogether?
Thanks,
Prafull.
