Android call recording implementation

Due to System Restrictions, only the voice of the microphone can be recorded, and the voice of the other speaker cannot be recorded. You may need to change the kernel to implement two-way recording;

When the phone is connected and the phone is hung up, shake it down;

Use broadcast receiver to enable auto-start;

 

Service Code:

 

Package com. eboy. phonelistener;

Import java. Io. file;

Import Android. App. Service;
Import Android. content. context;
Import Android. content. intent;
Import Android. Media. mediarecorder;
Import Android. OS. environment;
Import Android. OS. ibinder;
Import Android. OS. vibrator;
Import Android. telephony. phonestatelistener;
Import Android. telephony. telephonymanager;
Import Android. widget. Toast;

Public class phoneservice extends Service {

@ Override
Public ibinder onbind (intent arg0 ){
// Todo auto-generated method stub
Return NULL;
}

@ Override
Public void oncreate (){
// Todo auto-generated method stub
Super. oncreate ();
Telephonymanager = (telephonymanager) getsystemservice (context. telephony_service );
Telephonymanager. Listen (New phonelistener (), phonestatelistener. listen_call_state );
}

Private final class phonelistener extends phonestatelistener {
Private mediarecorder;
Private file;
Private vibrator = (vibrator) getsystemservice (vibrator_service );

@ Override
Public void oncallstatechanged (INT state, string incomingnumber ){
Try {

Switch (state ){
Case telephonymanager. call_state_ringing: // incoming call
Break;

Case telephonymanager. call_state_offhook: // call
File = new file (environment. getexternalstoragedirectory (), incomingnumber + system. currenttimemillis () + ". 3GP ");
Mediarecorder = new mediarecorder ();
Mediarecorder. setaudiosource (mediarecorder. audiosource. Mic );
Mediarecorder. setoutputformat (mediarecorder. outputformat. three_gpp );
Mediarecorder. setaudioencoder (mediarecorder. audioencoder. amr_nb );
Mediarecorder. setoutputfile (file. getabsolutepath ());
Mediarecorder. Prepare ();
Mediarecorder. Start ();
Toast. maketext (getapplicationcontext (), "The phone is connected and the recording starts. ", Toast. length_short). Show ();
// Vibrate
Vibrator. vibrate (100 );
Break;

Case telephonymanager. call_state_idle: // call up
If (mediarecorder! = NULL ){
Mediarecorder. Stop ();
Mediarecorder. Release ();
Mediarecorder = NULL;
Toast. maketext (getapplicationcontext (), "The phone has been hung up and the recording has stopped. ", Toast. length_short). Show ();
// Vibrate
Vibrator. vibrate (100 );
}
Break;
}

} Catch (exception e ){
E. printstacktrace ();
}
}
}
}

 

 

The broadcast receiver is used for self-starting. The Code is as follows:

Package com. eboy. phonelistener;

Import Android. content. context;
Import Android. content. intent;

Public class broadcastreceiver extends Android. content. broadcastreceiver {

@ Override
Public void onreceive (context arg0, intent arg1 ){
Intent service = new intent (arg0, phoneservice. Class );
Arg0.startservice (service );
}
}
