Android. System.out.println() doesn't work. What is the proper method to write?

Question

I used to write something like System.out.println(...); for tracing the information in Java.

But it doesn't write any messages to my IDE console, when I use it for programming for Android. What is the proper way to write to standard output stream?

I've always used the log functions though there might be a better way.

yeah, the system out is either through the screen or through your logcat. Read up on the DDMS – Stagleton Dec 20 '11 at 18:37

System.out.println() messages will come in the Logcat window in Eclipse, it wont come in Console window.
For Android it is better to use Log functions.

You must the android.util.Log class. This class ptint the logs in the LogCat view of Eclipse.

Log.v("SOMETAG", "Message for the log");
