I am currently working on an Android application that allows you to watch streaming video in a VideoView. I have a method for allowing you to select one of four streams via a switch statement. That is working correctly and the code for that is as follows:
public void playStream(int position) {
switch (position) {
case 0:
streamOn = true;
streamPos = 0;
logString = "M";
posSelected = "0";
break;
case 1:
streamOn = true;
streamPos = 1;
logString = "J";
posSelected = "1";
break;
case 2:
streamOn = true;
streamPos = 2;
logString = "B";
posSelected = "2";
break;
case 3:
streamOn = true;
streamPos = 3;
logString = "N";
posSelected = "3";
break;
default:
break;
}
checkStreamLink(position);
Log.wtf(logString, posSelected);
Log.wtf(logString, streamURL);
}
What is not working correctly is that in this method for selecting the stream, I have a call to another method ( checkStreamLink(); ) that runs a thread. Depending on which stream you have selected, the thread will call another method that opens up a webpage, reads a line of text, and then sets that text to a String streamURL. The code for those two methods is as follows:
public void checkStreamLink(final int position) {
Thread thread = new Thread(new Runnable() {
@Override
public void run() {
try {
switch (position) {
case 0:
streamURL = getStreamLink("LINK 0 GOES HERE");
break;
case 1:
streamURL = getStreamLink("LINK 1 GOES HERE");
break;
case 2:
streamURL = getStreamLink("LINK 2 GOES HERE");
break;
case 3:
streamURL = getStreamLink("LINK 3 GOES HERE");
break;
default:
break;
}
}
catch (Exception e) {
e.printStackTrace();
}
}
});
thread.start();
}
public String getStreamLink (String textSource) {
URL streamURL;
String errorParsingURL = "ERROR PARSING URL";
try {
streamURL = new URL(textSource);
BufferedReader bufferReader = new BufferedReader(new InputStreamReader(streamURL.openStream()));
String StringBuffer;
String stringText = "";
while ((StringBuffer = bufferReader.readLine()) != null) {
stringText += StringBuffer;
}
bufferReader.close();
return stringText;
}
catch (MalformedURLException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
}
return errorParsingURL;
}
The issue I'm having is that the String streamURL is returning null on its first use as evidenced by the Log statements I have included. Each time you select a stream after that, the String streamURL returns the text that you should have received the previous time you select a stream. I cannot seem to figure out why this is happening and I would appreciate any assistance.
