Hello venkat,

System.out.println is not working on Android, but there is sth at least same powerful 'replacement':
The so called 'LogCat'.

If you are using Eclipse, then you can goto Windows-> Show View -> Android -> LogCat.
- It should be visible in the DDMS-View by default

How to get to the DDMS-View (B if A is not visible):

If you are using the Command-Line:
- Browse the tools directory of your Android-SDK and...
- use: ` adb logcat `

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

android.util.Log: 
   Log.v (for verbose) 
   Log.d (for debug) 
   Log.i (for info) 
   Log.w (for warnings) 
   Log.e (for errors)
Parsed in 0.030 seconds,  using GeSHi 1.0.8.4

Usage in your code:

Using java Syntax Highlighting

private static final String TAG = "MyActivity";
Log.v(TAG, "index=" + i);
Parsed in 0.033 seconds,  using GeSHi 1.0.8.4

Hope I could help.

Hello rmeph,

I assume that you want to get the Text typed within the EditText, right :?:

So you need to extract the Text out of the EditText first:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

private static final String TAG = "MyActivity";
private EditText firstnameText;
 
firstnameText = (EditText) findViewById(R.id.firstname);
 
String s = firstnameText.getText().toString();
Log.v(TAG, "firstnameText =" + s );
Parsed in 0.035 seconds,  using GeSHi 1.0.8.4

Or did it show nothing in the LogCat :?:

(Really nothing or just not the one Log.v(...) from above :?:

)

Is there any other solutions to do that "easy java task" coz it works but on the log cat there are too many information lines in addition with the thing you want to display.

Hello LW,

Use Filters to control/filter the LogCat-Output:
