Android-Get the phone status

Whether it is a call or call, the system broadcast will send the corresponding message, we can listen to the broadcast to get the phone status.

First, configure your own broadcastreceiver in the manifest file and declare the permissions.

<Cycler Android: Name = ". filter. phonestatreceiver "> <br/> <intent-filter> <br/> <action Android: Name =" android. intent. action. phone_state "/> <br/> <action Android: Name =" android. intent. action. new_outgoing_call "/> <br/> </intent-filter> <br/> </Cycler> </P> <p> <uses-Permission Android: Name =" android. permission. read_phone_state "> </uses-Permission> <br/> <uses-Permission Android: Name =" android. permission. process_outgoing_cils "> </uses-Permission>
Handle it in your own broadcastreceiver
