When developing Android applications, it involves network access, often requiring network state checks to provide users with the necessary reminders. It is generally possible to complete the work by Connectivitymanager.Connectivitymanager has four main tasks:1, monitor the status of mobile phone network (including Gprs,wifi, UMTS, etc.)2, mobile phone status change, send broadcast3, when a network connection fails to failover4.

Permission required: Android. Permission. access_network_state
Common Methods:
1. getallnetworkinfo () // obtain all network connection information
2. getactivenetworkinfo () // get the information of the network that is being connected.
3. getnetworkinfo

In our work, we often need to use the network and check the network status is essential. This is a tool class for checking the current network status. It can be directly pasted in the past:

Sometimes we need to implement the conversion of cmwap and cmnet access methods. I have encountered this problem myself. After going online and searching for information, I can modify the apn table through a program to change the access method, however, after the switch, I tested it. It took about 6 to 8 seconds. I said it was 4 seconds on the Internet. I don't know how they
