As i have re-written this several times now. It is very nasty.
Im testing on a DroidX where everything i use to record a call is
coming back empty. Anyone know why or a fix?
My recording class:
[code]
package com.call.tests;

{
try
{
//recorder = new MediaRecorder();
if(incomingNumber.length() == 0)
incomingNumber = "noNumber";
Date dateNow = new Date ();
SimpleDateFormat dateformat = new
SimpleDateFormat("_kms_yyyyMMdd");
StringBuilder now = new
StringBuilder( dateformat.format( dateNow ) );
path = incomingNumber + now.toString();
Log.d("TEST", "NEW PATH: " + path);
String longPath = sanitizePath(path, false);
File directory = new File(longPath).getParentFile();
if (!directory.exists() && !directory.mkdirs()) {
Log.d("TEST", "Path to file could not be created.");
} else {
Log.d("TEST", "Path exists.");
}
rawRecorder = findAudioRecord();
rawRecorder.startRecording();
recording = true;
recordingThread = new Thread(new Runnable() {
@Override
public void run() {
writeAudioDataToFile();
}
},"AudioRecorder Thread");
