Solution 1

You need to look into doing standard IO with java.
There are System.in System.out and System.err please read about them here: Java IO: System.in, System.out, and System.err[^].

Java

System.out.println("Debug output");

[Modification]
I found this bit on SO where it says in one solution that in android System.out and System.err are redirected to /dev/null, effectively sending all your output into nirvana. Please read the details on SO: Is there a way to print to the console in an Android app?[^]

There is also an promising link sending you to this site: http://developer.android.com/tools/help/adb.html#logcat[^]

Thanks, tried, but its don't works for me, and I don't know why...

What exactly do you mean by "console". It looks as if this is an android application so what console exactly are you talking about?

I modified my solution as I found some relevant information about standard IO redirection on android.
Please see the modifications.

Cheers!

Console what I see in Eclipse.

Open the Logcat window in Eclipse and you will see it, if you don't, change your filter level on Logcat (I don't remember how off the top of my head, but if you Google for "logcat eclipse" you should find some information).
