You can check permissions, you just can't get its own Context because it is in another process.
The permission check functions on Context are for *you* to check whether *someone else* has a permission. The checkCalling and enforceCalling versions of these assume you are in the dispatching of an IPC call (from an IBinder, typically through an aidl interface) and check whether the uid of the caller process has the permission you are checking. The other ones let you explicitly specify the uid to check for if you are doing this elsewhere by explicitly passing in the uid/pid (retrieved from within the IPC with Binder.getCallingUid/Pid()). At the lowest level, you can use the PackageManager directly to see if a particular uid is holding a permission, and if needed map from a package name to a uid. (Though note if you are using package names, this means you must be getting that package name from the other side, and often this is not actually secure.)
