android - How to get application package name or UID which is trying to bind my service from onBind function?

Question

I have a service in an application, and I can reach this service from different applications. And when applications are tried to bind this service I want to know which application is trying to bind my service in onBind function, but I can't get the package name or UID of this application in onBind function.

Is it possible to get the application name or UID which is trying to bind my service in onBind function?

Answer 1

You can use the following to determine the calling application.

 String callingApp = context.getPackageManager().getNameForUid(Binder.getCallingUid());

It's important to note the JavaDoc for getCallingUid() which says:

Return the Linux uid assigned to the process that sent you the current transaction that is being processed. This uid can be used with higher-level system services to determine its identity and check permissions. If the current thread is not currently executing an incoming transaction, then its own uid is returned.
