Android Application development: Telephone listening and recording code example _android

Executing in OnCreate:

Copy Code code as follows:

public void OnCreate () {
Super.oncreate ();
LOG.I ("TAG", "service Started");

Monitor the caller status of the phone
Telephonymanager Telmanager = (Telephonymanager) This
. Getsystemservice (Context.telephony_service);
Register a listener to monitor the status of the phone
Telmanager.listen (New Myphonestatelistener (),
Phonestatelistener.listen_call_state);
}

Implement Myphonestatelistener:

Copy Code code as follows:

Private class Myphonestatelistener extends Phonestatelistener {
Mediarecorder Recorder;
File Audiofile;
String PhoneNumber;

public void oncallstatechanged (int state, String incomingnumber) {
Switch (state) {
Case TELEPHONYMANAGER.CALL_STATE_IDLE: * * without any State
if (recorder!= null) {
Recorder.stop (); Stop burning
Recorder.reset (); Re-set
Recorder.release (); Burn complete Make sure you release resources
}
Break
Case Telephonymanager.call_state_offhook: * * When the phone is picked up

try {
Recorder = new Mediarecorder ();
Recorder.setaudiosource (MediaRecorder.AudioSource.MIC); Set up audio capture original
Recorder.setoutputformat (MediaRecorder.OutputFormat.THREE_GPP); Content output Format
Recorder.setaudioencoder (MediaRecorder.AudioEncoder.AMR_NB); Audio encoding Mode

Recorder.setoutputfile ("/sdcard/myvoice.amr");
Audiofile = new File (
Environment.getexternalstoragedirectory (),
PhoneNumber + "_" + System.currenttimemillis ()
+ ". 3gp");
Recorder.setoutputfile (Audiofile.getabsolutepath ());
LOG.I ("TAG", Audiofile.getabsolutepath ());

Recorder.prepare (); Expected preparation
Recorder.start ();

catch (IllegalStateException e) {
E.printstacktrace ();
catch (IOException e) {
E.printstacktrace ();
}

Break
Case telephonymanager.call_state_ringing: * * When the phone came in
PhoneNumber = Incomingnumber;
Break
Default
Break
}
Super.oncallstatechanged (state, Incomingnumber);
}
}

Through the continuation of the two corresponding steps that can be implemented through the server to the telephone monitoring work, in Call_state_idle stateless (that is, idle state), Call_state_offhook phone call (that is, suspended), call_state_ringing The phone comes in (that is, when the call) executes in these several states.
