I am developing an application which enables user to make a voice call within a LAN (WI-FI) by streaming a raw pcm audio stream.
but I am unable to play the audio track being received
here is my receiver code:
private AudioTrack speaker;
public void startReceiving() {
Thread receiveThread = new Thread (new Runnable() {
#Override
public void run() {
try {
DatagramSocket socket = new DatagramSocket(1127);
Log.d("VR", "Socket Created");
byte[] buffer = new byte[256];
//minimum buffer size. need to be careful. might cause problems. try setting manually if any problems faced
int minBufSize = AudioRecord.getMinBufferSize(sampleRate, channelConfig, audioFormat);
speaker = new AudioTrack(AudioManager.STREAM_MUSIC,sampleRate,channelConfig,audioFormat,minBufSize,AudioTrack.MODE_STREAM);
speaker.play();
while(status==true) {
try {
DatagramPacket packet = new DatagramPacket(buffer,buffer.length);
socket.receive(packet);
Log.d("VR", "Packet Received");
//reading content from packet
buffer=packet.getData();
Log.d("VR", "Packet data read into buffer");
//sending data to the Audiotrack obj i.e. speaker
speaker.write(buffer, 0, minBufSize);
Log.d("VR", "Writing buffer content to speaker");
} catch(IOException e) {
Log.e("VR","IOException");
}
}
speaker.play();
} catch (SocketException e) {
Log.e("VR", "SocketException");
}
}
});
receiveThread.start();
}
and here is my sender code:
public void startStreaming()
{
Thread streamThread = new Thread(new Runnable(){
#Override
public void run()
{
try{
DatagramSocket socket = new DatagramSocket();
Log.d("VS", "Socket Created");
byte[] buffer = new byte[minBufSize];
Log.d("VS", "Buffer created of size " + minBufSize);
Log.d("VS", "Address retrieved");
recorder = new AudioRecord(MediaRecorder.AudioSource.MIC,sampleRate,channelConfig,audioFormat,minBufSize);
Log.d("VS", "Recorder initialized");
recorder.startRecording();
InetAddress IPAddress = InetAddress.getByName("192.168.0.101");
byte[] sendData = new byte[1024];
byte[] receiveData = new byte[1024];
while (status==true)
{
DatagramPacket sendPacket = new DatagramPacket(sendData, sendData.length, IPAddress, 1127);
socket.send(sendPacket);
}
} catch(UnknownHostException e) {
Log.e("VS", "UnknownHostException");
} catch (IOException e) {
Log.e("VS", "IOException");
e.printStackTrace();
}
}
});
streamThread.start();
}
I cant use SIP , its just a plain audio streaming.
can any one help me with this please
thanks.
You have two issues:
Your receiver thread doesn't seem to play... it is always in the loop and never reaches speaker.play().
Your sending thread never sends any data... For example:
recorder.read(sendData, 0, sendData.length);

l want to send live camera from phone 1 to phone 2 via wifi. What is the easiest way to do this ?
I Can sending my voice from phone 1 to phone 2 successful. but I can not send live camera to phon2.
I found " libstreaming " and " Sipdroid " that Used for communication stream(audio or live camera ) Between two devices. But I do not understand them And it is very difficult.
Is there an easier way to do it ?

I'm developing voice chat App.streaming voice between client and server.
i had tried with Datagramsocket but has a lota problems.
I'M trying with Tcp this time. but i couldn't transfer data.what's wrong with my code?
client :
public void startStreaming() {
Thread streamThread = new Thread(new Runnable() {
#Override

DatagramPacket packet;
final InetAddress destination = InetAddress.getByName(target.getText().toString());

i think the problem is transfering the voice.
please give me your best help
client side :
BufferedWriter input;
while(status == true) {
int bufferReadResult = recorder.read(buffer, 0, buffer.length);
dos.write(buffer,0,bufferReadResult);
dos.flush();
}
I have searched and found a code of voice streaming or audio calling between two android phones on simple sockets. I have implemented this , but this code is not working. I am unable to hear any voice.

I debugged the code , and packets are successfully transmitting and speaker.play() is also called. But there is no Voice
I have implemented this code in a single application and activity. With two Buttons Start Listening and Start Streaming
getMinBufferSize() may not be the same for AudioRecord and AudioTrack (learned that the hard way). Make sure you are using the larger of the two.
Everything is working fine for me... just want to ask that how to send packets on public IP like 119.43.214.5. I have made two apps and they can send packets on localhost Client have got the IP Address of server app. Just the problem is that IP is a public IP and client is not sending data on that app.
I'm trying to broadcast a audio file from my android device via udp to the local wifi and have the clients on the local network listen to it via VLC's network streaming option. I can broadcast it and recieve it on anydevice connected to the network if i use my own recieve code, But i want VLC to be able to play it. Is ther any specific encoding or formatting that needs to be done before I send the datagram packet?
My sending code
public void SendAudio()
{
Thread thrd = new Thread(new Runnable() {
#Override

{
Log.e(LOG_TAG, "start send thread, thread id: "

Once again, using this i can send this from one android device and listen from another just fine using the recieve code ive given, but i want to play it using vlc's get network stream command and listen to h77p://#:port and get the audio playing.
Tnx again :)
You can use the code from this tutorial:
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
try {
AudioManager audio = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
audio.setMode(AudioManager.MODE_IN_COMMUNICATION);
AudioGroup audioGroup = new AudioGroup();
audioGroup.setMode(AudioGroup.MODE_NORMAL);
AudioStream audioStream = new AudioStream(InetAddress.getByAddress(getLocalIPAddress ()));
audioStream.setCodec(AudioCodec.PCMU);
audioStream.setMode(RtpStream.MODE_NORMAL);
//set receiver(vlc player) machine ip address(please update with your machine ip)
audioStream.associate(InetAddress.getByAddress(new byte[] {(byte)192, (byte)168, (byte)1, (byte)19 }), 22222);
audioStream.join(audioGroup);
} catch (Exception e) {
Log.e("----------------------", e.toString());
e.printStackTrace();
}
}
public static byte[] getLocalIPAddress () {
byte ip[]=null;
try {
for (Enumeration en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
NetworkInterface intf = en.nextElement();
for (Enumeration enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
InetAddress inetAddress = enumIpAddr.nextElement();
if (!inetAddress.isLoopbackAddress()) {
ip= inetAddress.getAddress();
}
}
}
} catch (SocketException ex) {
Log.i("SocketException ", ex.toString());
}
return ip;
}
I need to show data to a TextView from a serial Bluetooth.
But when i connect my application with the serial device, it did connected but suddenly went forced closed. The logcat shows nothing so I don't know what's wrong.
This is the code when application listens the inputstream while connected:
public void run() {
Log.i(TAG, "BEGIN mConnectedThread");
byte[] buffer = new byte[1024];
int bytes;
while (true) {
try {
// Read from the InputStream
bytes = mmInStream.read(buffer);
//mEmulatorView.write(buffer, bytes);
mTextView.append(new String(buffer));
// Send the obtained bytes to the UI Activity
//mHandler.obtainMessage(BlueTerm.MESSAGE_READ, bytes, -1, buffer).sendToTarget();
String a = buffer.toString();
mTextView.setText(a);
a = "";
} catch (IOException e) {
Log.e(TAG, "disconnected", e);
connectionLost();
break;
}
}
}
and TextView mTextView = (TextView) findViewById(R.id.dataTerm);
and on the layout:
<TextView
android:id="#+id/dataTerm"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
So does anyone know what went wrong?
Any answers are so helpful, thanks..
The code that finally work
On the main file, in my case named FinalSetting:
On the Activity method, declare:
//Layout View
private static TextView mTextView;
On the onCreate(Bundle savedInstanceState) method declare the textview:
mTextView = (TextView) findViewById(R.id.dataTerm);
On the Handler method:
case MESSAGE_READ:
byte[] readBuf = (byte[]) msg.obj;
//mEmulatorView.write(readBuf, msg.arg1);
// construct a string from the valid bytes in the buffer
String readMessage = new String(readBuf, 0, msg.arg1);
//mConversationArrayAdapter.add(mConnectedDeviceName+": " + readMessage);
mTextView.setText(readMessage);
break;
On the BluetoothService.java file:
Let's just straight to the method
//This thread runs during a connection with a remote device.
//It handles all incoming and outgoing transmissions.
private class ConnectedThread extends Thread {
private final BluetoothSocket mmSocket;
private final InputStream mmInStream;
private final OutputStream mmOutStream;
public ConnectedThread(BluetoothSocket socket) {
Log.d(TAG, "create ConnectedThread");
mmSocket = socket;
InputStream tmpIn = null;
OutputStream tmpOut = null;
// Get the BluetoothSocket input and output streams
try {
tmpIn = socket.getInputStream();
tmpOut = socket.getOutputStream();
} catch (IOException e) {
Log.e(TAG, "temp sockets not created", e);
}
mmInStream = tmpIn;
mmOutStream = tmpOut;
}
public void run() {
Log.i(TAG, "BEGIN mConnectedThread");
byte[] buffer = new byte[1024];
//final byte[] buffer = new byte[1024];
int bytes;
// Keep listening to the InputStream while connected
while (true) {
try {
// Read from the InputStream
bytes = mmInStream.read(buffer);
//Send the obtained bytes to the UI Activity
mHandler.obtainMessage(FinalSetting.MESSAGE_READ, bytes, -1, buffer).sendToTarget();
} catch (IOException e) {
Log.e(TAG, "disconnected", e);
connectionLost();
break;
}
}
}
/**
* Write to the connected OutStream.
* #param buffer The bytes to write
*/
public void write(byte[] buffer) {
try {
mmOutStream.write(buffer);
// Share the sent message back to the UI Activity
mHandler.obtainMessage(FinalSetting.MESSAGE_WRITE, buffer.length, -1, buffer).sendToTarget();
} catch (IOException e) {
Log.e(TAG, "Exception during write", e);
}
}
public void cancel() {
try {
mmSocket.close();
} catch (IOException e) {
Log.e(TAG, "close() of connect socket failed", e);
}
}
}
After you connect to the serial Bluetooth device, the data will show up on the TextView.
Hope this help :D
Seems like you are trying to modify mTextView in a non-UI thread which is illegal and might be the reason for FC (if not any other issue). However you can achieve this as below:
Change this:
mTextView.append(new String(buffer));
To this:
mTextView.post(new Runnable() {
#Override
public void run() {
mTextView.append(new String(buffer));
}
});
