| /** |
| * A convenience wrapper for INetworkMonitor. |
| * |
| * Wraps INetworkMonitor calls, making them a bit more friendly to use. Currently handles: |
| * - Clearing calling identity |
| * - Ignoring RemoteExceptions |
| * - Converting to stable parcelables |
| * |
| * By design, all methods on INetworkMonitor are asynchronous oneway IPCs and are thus void. All the |
| * wrapper methods in this class return a boolean that callers can use to determine whether |
| * RemoteException was thrown. |
