| 16 | Binder is used in Android for both communication between processes, |
| 17 | and remote method invocation. |
| 18 | |
| 19 | This means one Android process can call a method/routine in another |
| 20 | Android process, using Binder to identify, invoke and pass arguments |
| 21 | between said processes. |

| 30 | The binder.devices parameter is a comma-separated list of strings |
| 31 | that specifies the names of the binder device nodes that will be |
| 32 | created. Each binder device has its own context manager, and is |
| 33 | therefore logically separated from the other devices. |
