[android-developers] NullPointerException ... arrrggghhh ... newbie LOST!

[KinnMirr]

When I run below activity, I get an exception. I've wrapped the exception 
in an AlertDialog. Here's what the dialog shows.
*  null
  null
  null
  java.lang.NullPointerException
*
Where do I even START looking for a problem?
I've commented-out everything I can think of and the exception still 
happens.
ar! 
I'm a newbie and I'm stumped!
Here's the Activity
AlertDialog marked with  

import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class EncDocRetrieve extends Activity {
  Button retrieveDoc;
  //EditText DocName;
  @Override
  public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
  setContentView(R.layout.activity_enc_doc_retrieve);
  retrieveDoc = (Button) findViewById(R.id.btnRetrieveDoc);
  retrieveDoc.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
  //DocName = (EditText) 
findViewById(R.id.edtextDocUserName);
  Intent intent = new 
Intent(EncDocRetrieve.this,
  DecryptKeyGet.class);
  
//intent.putExtra(android.content.Intent.EXTRA_TEXT, DocName
  //.getText().toString());
  startActivity(intent);
}
  });
  } catch (Exception e) {
AlertDialog.Builder dialog = new 
AlertDialog.Builder(this);
dialog.setTitle(Opps Exception);
String err = e.getLocalizedMessage() + \n + 
e.getCause() + \n  + e.getMessage() + \n + e.toString();
dialog.setMessage(err);
dialog.setNeutralButton(Cool, null);
dialog.create().show();
}
  }
  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_enc_doc_retrieve, 
menu);
return true;
  }
}

[android-developers] Re: how to set two spinners with different strings and icons?

[KinnMirr]

First ... the program is only doing EXACTLY what you're telling it to do. 
Believe that.
 
So, somewhere you're telling it to do the same thing twice.
 
Check that each spinner has a different ID
Check your population routines target two different spinner ID.
 
Then, look close at every line of code ... like it was the first time you 
wrote it and go through the PROGRAMMING again in your head.
 
If that doesn't work ... you better just post the Activity and Layout here 
for others to look at.
Maybe we can see something you're overlooking!
