start audio clip in background in android at a particular time

start audio clip in background in android at a particular time - android

I am creating an android app in which I want to put clock ticking sound in the background and that too for last few seconds.
the audio is for 21 sec and i too want it to be played in last 21 seconds of the timer. The actual timer is running for 2 minutes.
I was trying the following code :
public void onTick(long millisUntilFinished) {
// TODO Auto-generated method stub
millis = millisUntilFinished;
if(millis == 21000){
mp1.start();
}
hms = String.format("%02d:%02d",
TimeUnit.MILLISECONDS.toMinutes(millis) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
TimeUnit.MILLISECONDS.toSeconds(millis) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));
timer.setText(hms);
}
where mp1 is :
mp1 = MediaPlayer.create(AnimalMain.this,R.raw.tick_tock);
But nothing is getting played. Also, I am getting the error in the log cat as :
should have subtitle controller already set
I tried many of the stackoverflow links with the same issue but could not resolve it using them. Please Help.
For any reference, please see the entire code here:

}

It can be done by simply adding delay instead of checking timer value in the OnTick() which will not work. The delay can be added in the following way :
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
// Do something after 5s = 5000ms
mp1.start();
mp1.setLooping(true);
}
}, 100000);
put the delay after which you want to start the audio in background and it worked in my case.

Android Realtime Signal not smooth using graphview library

Iam trying to plot realtime signal from arduino to my android tablet. I've using a potentiometer for testing purpose and ADC sampling rate is 256Hz.
My issue is that the graph plotted on the android app is not smooth. The serial communication is working properly but the plotting is not very good.It feels like the App is lagging and it lags further as the data gets plotted.
Below is the app image

You need to enable bidirectional text direction.
As usual click Window > Preferences > General > Globalization > Enable bidirectional support. Don't forget to restart your eclipse for it to take effect.

Why does my application crash sometimes?

All,
I would greatly appreciate some help. We have a system that is being sent data at 2 Hz (every 0.5 sec). My application is supposed to start acquiring this data upon the press of a "start" button through a handler, and upon pressing the "stop" button, the user can choose to save the data collected. If save is chosen, a new activity is SUPPOSED to be started, however, my application crashes. The error message:
java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.String.indexOf(int)' on a null object reference

Any thoughts on this? I'm completely out of ideas on what is causing this to crash... something with the bluetooth connectivity, maybe?
Thanks,
John

fromBluetooth is null, and you can't call indexOf(...) on a null String.
You must therefore ensure that fromBluetooth isn't null (good) or handle the case where fromBluetooth is null (better) (e.g. if (fromBluetooth != null) execute logic).
Enjoy

Replace your code
if(fromBluetooth!=null){
tempString = fromBluetooth.substring(fromBluetooth.indexOf('\t')+1);
}
with
fromBluetooth.substring(fromBluetooth.indexOf('\t')+1);
because you not checking string is null or not and directly findvalue using indexOf();

change the direction of chapters typing

I want to change direction of typing letter from Left To RIGHT
this is Image of this game
this is image of the game:
http://img11.hostingpics.net/pics/357754Capturedcran20150407103535.png
Normally when i type letter it will be in left case , I want to change it to right case

DatagramSocket.receive only receives the first two Datagrams

I am sending some data to an android application over UDP. Therefore i created the following UDPReceiver-Class:
package com.example.urowatch;
import java.net.*;
import java.nio.ByteBuffer;
import java.io.*;
public class UDPReceiver extends Thread
{
private DatagramSocket m_Socket;
private int m_BufferSize;
private Boolean m_End = false;
private int m_TotalLength;
private int m_Received;
private byte[] m_Buffer;
private byte[] m_Result;
private Boolean m_IsNewResult = false;
private float m_Progress;
private int m_ImageCount = 0;
private int m_FrameErrors = 0;
public UDPReceiver(String name, int port, int bufferSize) throws IOException
{
super(name);
m_Socket = new DatagramSocket(port);
m_BufferSize = bufferSize;
m_Socket.setBroadcast(true);
m_Socket.setReceiveBufferSize(m_BufferSize);
}
public void run()
{
while(!m_End)
{
try
{
byte[] buf = new byte[m_BufferSize];
DatagramPacket packet = new DatagramPacket(buf, buf.length);
m_Socket.receive(packet);
ProcessData(packet);
}
catch (IOException e)
{
if (!m_Socket.isClosed())
e.printStackTrace();
}
}
}
private void ProcessData(DatagramPacket packet)
{
if (packet.getLength() == 4)
{
ByteBuffer bb = ByteBuffer.wrap(packet.getData());
m_TotalLength = bb.getInt();
if (m_Received != 0)
m_FrameErrors++;
m_Received = 0;
m_Buffer = new byte[m_TotalLength];
}
else if (m_Buffer != null && m_Received != m_TotalLength)
{
int length = packet.getLength();
System.arraycopy(packet.getData(), 0, m_Buffer, m_Received, length);
m_Received += length;
m_Progress = 100 * (float)m_Received/(float)m_TotalLength;
if (m_Received == m_TotalLength)
{
m_Result = new byte[m_TotalLength];
System.arraycopy(m_Buffer, 0, m_Result, 0, m_TotalLength);
m_IsNewResult = true;
m_ImageCount++;
m_Received = 0;
}
}
}
public Boolean IsNewResult()
{
return m_IsNewResult;
}
public byte[] GetResult()
{
m_IsNewResult = false;
return m_Result;
}
public float GetProgress()
{
return m_Progress;
}
public float GetRatio()
{
return 100 * (float)m_ImageCount / (float)m_FrameErrors;
}
public void stopServer()
{
m_End = true;
if (m_Socket != null)
m_Socket.close();
}
}
And i am using this class like this:
package com.example.urowatch;

m_ImageView1 = (ImageView)findViewById(R.id.imageView1);

m_Context = this;
m_DF = new DecimalFormat("00.00");
}
/**

return true;
}
#Override

switch (item.getItemId()) {
case android.R.id.home:

NavUtils.navigateUpFromSameTask(this);
return true;
}
return super.onOptionsItemSelected(item);
}
private static Handler MyHandler = new Handler()
{
#Override
public void handleMessage(Message msg)
{
if (msg.what == 100)
{
float[] infos = (float[])msg.obj;
m_TextView1.setText("Empfange Bild: " + m_DF.format(infos[0]) + "% (FrameErrors: " + m_DF.format(infos[1]) + "%)");

{
byte[] b = (byte[])msg.obj;
m_TextView1.setText("Empfange Bild: 100,00%");
m_ImageView1.setImageBitmap(BitmapFactory.decodeByteArray(b, 0, b.length));
}
else if (msg.what == 102)
{
AlertDialog.Builder b = new AlertDialog.Builder(m_Context);
b.setTitle("Fehler");
b.setMessage("Es ist folgende Exception aufgetreten:\n" + (Exception)msg.obj);
b.setNeutralButton("OK", null);
b.show();
}
}
};
#Override
public void onBackPressed() {
super.onBackPressed();
if (m_Receiver != null)
m_Receiver.stopServer();
finish();
}
#Override

}
#Override

{
try {

m_Receiver.start();
} catch (IOException e1)
{
// TODO Auto-generated catch block

}
// Thread thread = new Thread()

Toast.makeText(getBaseContext(), "Runing Thread", Toast.LENGTH_SHORT).show();

// } catch (InterruptedException e) {

super.onResume();
}
public void buttonClick(View v)
{
Update();
}
private void Update()
{
if (m_Receiver != null)
{
if (m_Receiver.IsNewResult())
{
byte[] b = m_Receiver.GetResult();
MyHandler.sendMessage(MyHandler.obtainMessage(101, b));
}
else
{
float[] infos = new float[2];
infos[0] = m_Receiver.GetProgress();
infos[1] = m_Receiver.GetRatio();
MyHandler.sendMessage(MyHandler.obtainMessage(100, infos));
}
}
}
}
As you see i want to check the status of the UDPReceiver-Object (Is there a new complete byte[] ready?) by a thread. To update the GUI, the thread has to send a Message to MyHandler which will update the GUI.
In the moment i have to to click a button to raise the buttonClick-Event. Later on i want to do this in the commented thread-structure.
Now, here's my problem:
I start the Activity and everything works fine. Then i am starting to send ONE packet manually with my UDP-Sender (which works, i validated it with a C#-UDP-Receiver). The first packet get received fine. Then i send the second packet which get received, too. But from now on, my breakpoint at m_Socket.receive(packet); wont get hit anymore!
I have NO idea what this behaviour causes and it is very important for me to make this application work.
Please, if you have ANY Idea or just a guess, please let me know.
