Is Android's Binder implementation always non-blocking for "void method"-calls without parameters?

Question

Will IPC "void method"-calls without any parameters block the current thread/process? Or will the kernel just pause the caller-process/thread until the call finishes because the called process may do further IPC callbacks?

No, depends on the definition of the specific AIDL declaration of the function. If the AIDL defines the function as one way, then it's non-blocking, otherwise it's blocking.
