Hello venkat,

If I have some final values I prefer to store them in a public Interface. Sample from AndNav:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

public interface Constants {
 
        /** Overall DebugTag for whole AndNav. */
 
        public final String DEBUGTAG = "ANDNAV_DEBUGTAG";
 
        /** Shall be used if only one SubActivity is closed.*/
 
        public final int SUBACTIVITY_RESULTCODE_UP_ONE_LEVEL = 0;
 
        /** Shall be used if a chain of SubActivities is to be closed.*/
 
        public final int SUBACTIVITY_RESULTCODE_CHAINCLOSE = SUBACTIVITY_RESULTCODE_UP_ONE_LEVEL + 1;
 
        /** Shall be used to go back one level in the dialog-process. */
 
        public final int SUBACTIVITY_RESULTCODE_SUCCESS = SUBACTIVITY_RESULTCODE_CHAINCLOSE + 1;
 
}

Hello venkat,

you want a closer description :?:

I don't know what to explain more

You create new Interface, define some finals in there and use them somewhere in other Activities, like this:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

                                try{
 
                                        /* Parse the caption to an Integer. */
 
                                        int i = Integer.parseInt(theCaption);
 
                                        /* And append it to the zipCodeEditText. */
 
                                        SDZip.this.zipCodeEditText.getText().append("" + i);
 
                                }catch(NumberFormatException nfe){
 
                                        Log.e(Constants.DEBUGTAG, "numberPadGrid-onItemClick", nfe);
 
                                }
