I managed to create an application in Blackberry that plays audio file, but it will only plays one file. I try to use a for loop to play a few audio files.
I managed to play it, but it did not play the whole sound of the audio files, it just play the first audio files and second for a few seconds, and stop playing after that. The files that played also play the sound overlap each other which should not be happening.
How to play the full sound of the audio files one after another in Blackberry without stopping?
Here is my code for the application that I created with the for loop:
package mypackage;
import javax.microedition.media.Manager;
import javax.microedition.media.MediaException;
import javax.microedition.media.Player;
import java.lang.Class;
import javax.microedition.rms.RecordStore;
import java.io.InputStream;
import java.io.ByteArrayInputStream;
import net.rim.device.api.media.protocol.ByteArrayInputStreamDataSource;
import net.rim.device.api.system.*;
import net.rim.device.api.ui.*;
import net.rim.device.api.ui.component.*;
import net.rim.device.api.ui.container.MainScreen;
import net.rim.device.api.ui.extension.container.*;
import net.rim.device.api.ui.UiApplication;
import java.io.IOException;
public class PlayMedia extends UiApplication{
/**
* Entry point for application
* @param args Command line arguments (not used)
*/
public static void main(String[] args){
PlayMedia theApp = new PlayMedia();
theApp.enterEventDispatcher();
}
public PlayMedia()
{
pushScreen(new PlayMediaScreen());
}
/**
* A class extending the MainScreen class, which provides default standard
* behavior for BlackBerry GUI applications.
*/
final class PlayMediaScreen extends MainScreen
{
/**
* Creates a new PlayMediaScreen object
*/
PlayMediaScreen()
{
String test1 = "Test(2seconds).mp3";
String test2 = "Test(2seconds)2.mp3";
String test3 = "Test(2seconds)3.mp3";
String test4 = "Test(2seconds)4.mp3";
String test5 = "blind_willie.mp3";
String mp3 = null;
for(int i=0;i<5;i++){
if(i == 0){
mp3 = test1;
}
else if(i == 1){
mp3 = test2;
}
else if(i == 2){
mp3 = test3;
}
else if(i == 3){
mp3 = test4;
}
else if(i == 4){
mp3 = test5;
}
play(mp3);
}
}
private void play(String mp3){
Player p = null;
InputStream stream = (InputStream)this.getClass().getResourceAsStream("/" + mp3);
try {
//p = Manager.createPlayer(source);
p = Manager.createPlayer(stream, "audio/mpeg");
p.realize();
p.prefetch();
//testing
System.out.println("Creating Players!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
System.out.println("The mp3 is " + mp3 + "!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
//testing
System.out.println("IO Exeception!!!!!!!!!!!!!!!!1 " + e);
//testing
System.out.println(p);
} catch (MediaException e) {
// TODO Auto-generated catch block
e.printStackTrace();
//testing
System.out.println("Media Exeception!!!!!!!!!!!!!!!!1" + e);
//testing
System.out.println(p);
}
/*
* Best practice is to invoke realize(), then prefetch(), then start().
* Following this sequence reduces delays in starting media playback.
*
* Invoking start() as shown below will cause start() to invoke prefetch(0),
* which invokes realize() before media playback is started.
*/
try {
p.start();
} catch (MediaException e) {
// TODO Auto-generated catch block
e.printStackTrace();
//testing
System.out.println("Media Exeception for starting!!!!!!!!!!!!!!!!1" + e);
//testing
System.out.println(p);
}
/*try {
p.stop();
} catch (MediaException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}*/
//p.deallocate();
//p.close();
}
}
}
Finally I get it, this is my code. 😀
