I have created one service and broadcast receiver to get telephony state.
Below is my code :
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
final IntentFilter filter = new IntentFilter();
filter.addAction(ACTION_OUT);
filter.addAction(ACTION_IN);
if (br_call == null) {
br_call = new CallBr();
registerReceiver(br_call, filter);
}
return super.onStartCommand(intent, flags, startId);
}
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ACTION_IN)) {
if ((bundle = intent.getExtras()) != null) {
state =bundle.getString(TelephonyManager.EXTRA_STATE);
Log.d("tag", "state ::" + state);
if (!wasRinging) {
if(state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
inCall=bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
wasRinging = true;
Toast.makeText(context, "IN : " + inCall, Toast.LENGTH_LONG).show();
}
}
if(state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)){
if (wasRinging) {
Toast.makeText(context, "ANSWERED", Toast.LENGTH_LONG).show();
if (recorder == null) {
File sampleDir = new File(Environment.getExternalStorageDirectory(), "/RecordingDemo");
if (!sampleDir.exists()) {
sampleDir.mkdirs();
}
String file_name = inCall;
try {
audiofile = File.createTempFile(file_name, ".amr", sampleDir);
} catch (IOException e) {
e.printStackTrace();
}
String path = Environment.getExternalStorageDirectory().getAbsolutePath();
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);
recorder.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(audiofile.getAbsolutePath());
try {
recorder.prepare();
recorder.start();
recordstarted = true;
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
wasRinging = false;
Toast.makeText(context, "REJECT || DISCONNECT", Toast.LENGTH_LONG).show();
if (recordstarted) {
try {
recorder.stop();
recordstarted = false;
} catch (RuntimeException e) {
e.printStackTrace();
}
}
}
}
}
if (intent.getAction().equals(ACTION_OUT)) {
if ((bundle = intent.getExtras()) != null) {
outCall = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Toast.makeText(context, "OUT : " + outCall, Toast.LENGTH_LONG).show();
}
}
}
}
I am facing below two issues
1) i have printed log in code for different states, but all states are printing multiple times and audio file is also created multiple times for same call.
2) if once i kill the app and start again, many times it wont record any calls. i have to add new build only.
Finally, I have found a solution. Please try following code.
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent == null || !ACTION.equals(intent.getAction())) {
return super.onStartCommand(intent, flags, startId);
}
String state = intent.getStringExtra(STATE);
String phoneNo = intent.getStringExtra("android.intent.extra.PHONE_NUMBER");
Log.d("tag", "state: " + state + " phoneNo: " + phoneNo);
if (OUTGOING.equals(state)) {
fileNamePrefix = "mob_no_s" + phoneNo + "mob_no_d" + OUTGOING_CALL_SUFFIX;
} else if (INCOMING.equals(state)) {
fileNamePrefix = "mob_no_s" + phoneNo + "mob_no_d" + INCOMING_CALL_SUFFIX;
} else if (BEGIN.equals(state)) {
if (SecurePreferences.getBooleanPreference(this, Constants.PREF_RECORD_CALLS)) {
try {
startRecording();
} catch (IOException e) {
e.printStackTrace();
}
}
} else if (END.equals(state)) {
try {
stopRecording();
} catch (IOException e) {
e.printStackTrace();
}
} else if (STORAGE.equals(state)) {
if ("mounted".equals(Environment.getExternalStorageState())) {
prepareAmrDir();
} else {
isMounted = false;
}
if (!isInRecording) {
stopSelf();
}
}
return START_STICKY;
}
public Context getContext() {
return cntx;
}
private void stopRecording() throws IOException {
updateNotification(Boolean.valueOf(false));
if (isInRecording) {
isInRecording = false;
try {
recorder.stop();
recorder.release();
recorder = null;
} catch (IllegalStateException e) {
e.printStackTrace();
}
releaseWakeLock();
if (SecurePreferences.getBooleanPreference(this, Constants.PREF_SAVE_RECORDING)) {
Intent intent = new Intent(this, AutoRunReceiver.class);
intent.putExtra("absolutepath", amr.getAbsolutePath());
sendBroadcast(intent);
}
stopSelf();
Log.d("tag", "call recording stopped");
}
}
