chose the equals function to start, because this is the simplest and most convenient, only the Init method inside the two calls, will not affect the other places:, in the last side of the execution of the Equals method, R0 as the register of the return data, which is deposited in the judgment result, as long as the R0 deposit immediately 1, you can return the same judgment results, then began to consult arm's instruction machine code (ARMV7-M Architecture Application level Reference Manual), qu

Android applications connected to IOT generally start with the welcome interface to check the network status and synchronize the background server. If the network status is unavailable, the user must be notified that the current network is unavailable, the following describes how to implement this function. Public s
