I avoid the exception with using of narrow-down variable scope.
Actually my friend suggest it me.
<previous code>
public class study004statuswithprogressbar extends Activity {
@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
switch (event.getUnicodeChar() - '0') {
case 1:
//Some Code Here
if ( progressIncrementthread.isAlive() == false )
{
progressIncrementthread.start();
}
}
ProgressThread progressIncrementthread = new
ProgressThread(uploadProgressBarHandler);
private class ProgressThread extends Thread {
}
}
<new code>
public class study004statuswithprogressbar extends Activity {
@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
switch (event.getUnicodeChar() - '0') {
case 1:
//Some Code Here
ProgressThread progressIncrementthread = new
ProgressThread(uploadProgressBarHandler);
if ( progressIncrementthread.isAlive() == false )
{
progressIncrementthread.start();
}
}
//Move it to switch
//ProgressThread progressIncrementthread = new
ProgressThread(uploadProgressBarHandler);
private class ProgressThread extends Thread {
}
}
It works!!
I think this is very smart way to avoid the problem.
But I still want to solve the problem instead of using variable scope.
Does anybody can do it?
Please suprise me. =)
