How to output messages to the Eclipse console when developing for Android

Question

How can I print messages  like a flag  to the Eclipse console  or log  when developing and debugging an Android app

System out println   also outputs to LogCat  The benefit of using good old System out println   is that you can print an object like System out println object  to the console if you need to check if a variable is initialized or not    Log d  Log v  Log w etc methods only allow you to print strings to the console and not objects  To circumvent this  if you desire   you must use String format

Rather than trying to output to the console  Log will output to LogCat which you can find in Eclipse by going to  Window- Show View- Other   - Android- LogCat  Have a look at the reference for Log   The benefits of using LogCat are that you can print different colours depending on your log type  e g   Log d prints blue  Log e prints orange  Also you can filter by log tag  log message  process id and or by application name  This is really useful when you just want to see your app s logs and keep the other system stuff separate

Log v  blah    blah blah      You need to add the android Log view in eclipse to see them  There are also other methods depending on the severity of the message  error  verbose  warning  etc
