An example analysis of Telephonymanager class in Android _android

The examples in this article describe the methods of Telephonymanager classes in Android. Share to everyone for your reference. Specifically as follows:

The Telephonymanager class mainly provides a series of get methods for accessing state and information related to mobile communications. This includes the status and information of Mobile SIM, the status of telecom network and the information of mobile phone users. You can use these get methods in your application to obtain related data.

The object of the Telephonymanager class can be obtained by the Context.getsystemservice (Context.telephony_service) method, and it should be noted that some communication information is restricted to the permission of the application. , you need to add the appropriate permissions to it when you develop it.

All methods and descriptions for the Telephonymanager class are listed below:
