Apps HashMap Population

[try2learn]

Hello all, have been struggling with this and am rather frustrated with my lack of ability.
Basically I would like to populate my hashMap with words read in from a dictionary file. I have about seven different versions of this attempt.

package ie.gmit;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.HashMap;
import java.util.Map;

import android.app.Activity;

public class DictionaryMap extends Activity {

	
	Map wordMap= new HashMap();
	
	public void load() throws Exception{
		InputStream is = getResources().openRawResource(R.raw.dictionary);
		try {
			BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF8")); 

			String next;
			while ((next = br.readLine()) != null) { 
				String word=next;
				int wlength=word.length();
				wordMap.put(wlength, word); 
				
				//Collection wCollection=wordMap.values();
				
				//Iterator wordItr=wCollection.iterator();
			}

		} catch (Exception e) {
			throw new Exception("[ERROR] Encountered a problem reading the dictionary. " + e.getMessage());		
		}
		((DictionaryMap) wordMap).getWordMap();
	}
	public int size(){
		return wordMap.size();
	}
	
	public Map getWordMap(){
		return wordMap;
	}
}

I have tried to search that hashmap but am unsure how far the program is getting if anywhere at all.

package ie.gmit;

import java.util.Map;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class WordSearch extends Activity {
	
	@Override
	public void onCreate(Bundle savedInstanceState)  {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		try {
			init();
		} catch (Exception e) {
			//aaaaaaaaahhhh
		}
	}
	
	public void init() throws Exception{
		
		DictionaryMap dictionary = new DictionaryMap();
		dictionary.load();
		//Toast.makeText(getApplicationContext(), "init started", Toast.LENGTH_LONG).show();
		
		final Map wordMap=dictionary.getWordMap();
		
		final String searchTerm="@+id/txtsearchClue";
		final int searchTermLength=searchTerm.length();
		Button btnSearch=null;
		
		btnSearch = (Button)  findViewById(R.id.btnSearch);
		btnSearch.setOnClickListener(new View.OnClickListener() {
	        public void onClick(View v) {
	        	if(wordMap.containsKey(searchTermLength)){
	        		if(wordMap.containsValue(searchTerm)){
	        			Toast.makeText(getApplicationContext(), "Found", Toast.LENGTH_LONG).show();
	        		}
	        	}else
	        		Toast.makeText(getApplicationContext(), "key not Found", Toast.LENGTH_LONG).show();
	        	
	        }
		});
	}

}

Is this even the right way to go about setting up my map?
any help would be much appreciated.

I took a quick gander and didn't see anything directly wrong. I suggest it would help alot if you didn't try catch the init(); call in your activity. This way the application will force close and your LogCat will show you a stack trace of exactly what went wrong. If you post that stack trace here I'll be willing to take a more detailed look at it.
