'If' condition is true but 'else' is being executed

The if condition is true but the code in else snippet gets executed.

enter image description here

I have already tried restarting the Eclipse, it didn't help.

It seems there are two problems.

Problem 1:

First problem was with getCurrentPosition() method of the MediaPlayer

mediaPlayer.stop();
mediaPlayer.getCurrentPosition(); // The current position in milliseconds

In the above code, the second line returns 8549 while the mediaPlayer was stopped already. I was asuming that after stoping the media player, the getCurrentPosition method will return zero milliseconds.

Problem 2:

The second problem (which is actually the answer to this post) was with the debugger. It seems its a bug in debugger.

mPlayer.getCurrentPosition() // value in debugger is 0 (as shown in the screenshot in OP)
mPlayer.getCurrentPosition() == 0 // value in debugger is true (as shown in the screenshot in OP)

But when I log the exact same thing in logcat, it gives different results:

Log.d("pos", mPlayer.getCurrentPosition()+""); // prints a non-zero value in log, in my case 8549
Log.d("con", String.valueOf( mPlayer.getCurrentPosition() == 0 ) ); // prints a false value in log

Which clearly shows why the else code snippet was being executed and why we should not blindly rely on the debugger sometimes :-P

Summary

Whenever you see such dramatic behaviour in debugger, try logging the variables in logcat. (Credit goes to Wakim, because his comment gave me the direction)

have you tried

mPlayer.getCurrentPosition().equals("0")

also try placing the codes in if block in else block (vice versa)
