In the previous article, I learned about the telephony class in Android.provider.
This article learns the classes in the Android.telephony package, which are the APIs that Android provides to the upper call.
A series of APIs for monitoring basic telephone information. such as network type, connection status. The tool class that operates the phone number.
Altogether 25 classes. The following describes each:
Telephonymanager
Processing the telephony information on the device, the application can use these methods to detect the status of the phone, processing the user's information type. It is also possible to register a listener to receive notification of changes in phone status. The class cannot be instantiated directly and is capable of
Context.getsystemservice (Context.telephony_service)
To obtain the instance. If you want to access protected information, you need to configure the appropriate permissions in the configuration file.
