Remarks
Sets the work source for this thread.
All the following binder calls on this thread will use the provided work source. If this is called during an on-going binder transaction, all the following binder calls will use the work source until the end of the transaction.
The concept of worksource is similar to WorkSource. However, for performance reasons, we only support one UID. This UID represents the original user responsible for the binder calls.
#restoreCallingWorkSource(long) must always be called after setting the worksource.
A typical use case would be
long token = Binder.setCallingWorkSourceUid(uid);
try {
// Call an API.
} finally {
Binder.restoreCallingWorkSource(token);
}
The work source will be propagated for future outgoing binder transactions executed on this thread.
