| 15 | Binder is used in Android for both communication between processes, |
| 16 | and remote method invocation. |
| 17 | |
| 18 | This means one Android process can call a method/routine in another |
| 19 | Android process, using Binder to identify, invoke and pass arguments |
| 20 | between said processes. |

| 27 | Default value for the binder.devices parameter. |
| 28 | |
| 29 | The binder.devices parameter is a comma-separated list of strings |
| 30 | that specifies the names of the binder device nodes that will be |
| 31 | created. Each binder device has its own context manager, and is |
| 32 | therefore logically separated from the other devices. |

| 40 | applications in a mixed environment. |

| 43 | earlier). |
| 44 | |
| 45 | Note that enabling this will break newer Android user-space. |
