Intent crashes my app

I am currently trying to call another activity via a OptionsMenuItem using Intent. I have 2 layouts. The 1st layout has a EditText with a string that is retrieved from a database. The 2nd layout also have a EditText which is empty. The OptionsMenuItem is in the 1st layout. Whenever I click on the MenuItem, it is supposed to call up the 2nd layout and extract the text from the 1st layout into the EditText in the 2nd layout, but instead it crashes. I tried using the ActivityResult way but I still can't get it to work. Hope you guys can help me out.

This is my java code where the intent is for the main activity with the 1st layout:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    super.onCreateOptionsMenu(menu);

    // Build the menus that are shown when editing.
    if (mState == STATE_EDIT) {
        menu.add(0, REVERT_ID, 0, R.string.menu_revert)
                .setIcon(android.R.drawable.ic_menu_revert);
        if (!mNoteOnly) {
            menu.add(0, DELETE_ID, 0, R.string.menu_delete)
                    .setIcon(android.R.drawable.ic_menu_delete);
            menu.add(1, ADD_ID, 1, R.string.add_namespace);
            menu.add(2, MENU_ITEM_ADD, 2, R.string.menu_add)开发者_JS百科;
        }

    // Build the menus that are shown when inserting.
    } else {
        menu.add(0, DISCARD_ID, 0, R.string.menu_discard)
                .setIcon(android.R.drawable.ic_menu_delete);
            menu.add(1, ADD_ID, 1, R.string.add_namespace);
    }

    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle all of the possible menu actions.
    switch (item.getItemId()) {
    case DELETE_ID:
        deleteNote();
        finish();
        break;
    case DISCARD_ID:
        cancelNote();
        break;
    case REVERT_ID:
        cancelNote();
        break;
    case ADD_ID:
     addNamespace();
     break;
    case MENU_ITEM_ADD:
     testActivity();
         break;
    }
    return super.onOptionsItemSelected(item);
}
private final void testActivity()
{
 Intent i = new Intent(this, TitleEditor.class);
 startActivityForResult(i, STATIC_INTEGER_VALUE);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
 super.onActivityResult(requestCode, resultCode, data);

 switch(requestCode)
 {
  case(STATIC_INTEGER_VALUE):
  {
   if(resultCode == Activity.RESULT_OK)
   {
    newTextTemplate = (EditText) findViewById(R.id.smsTemplate);
String newTemplate = data.getStringExtra(TitleEditor.PUBLIC_STATIC_STRING_IDENTIFIER);
    newTextTemplate.setText(newTemplate);
   }
   break;
  }
 }
}

This is my java code with the 2nd layout:

public class TitleEditor extends Activity implements View.OnClickListener {

    private static final String[] PROJECTION = new String[] {
            NotePad.Notes._ID, // 0
            NotePad.Notes.TITLE, // 1
            NotePad.Notes.TEMPLATE, // 2
    };

    private static final int COLUMN_INDEX_TITLE = 1;
    private static final int COLUMN_INDEX_TEMPLATE = 2;

    private Cursor mCursor;

    private EditText mToContacts;
    private EditText mFromTemplate;

 public static final String PUBLIC_STATIC_STRING_IDENTIFIER = null;

    private Uri mUri;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.title_editor);

        mUri = getIntent().getData();

        mCursor = managedQuery(mUri, PROJECTION, null, null, null);

        mFromTemplate = (EditText) this.findViewById(R.id.smsTemplate);
        mFromTemplate.setOnClickListener(this);

        Button b = (Button) findViewById(R.id.ok);
        b.setOnClickListener(this);


    }

    public void onClick(View v) {
     Intent resultIntent = new Intent();
  resultIntent.putExtra(PUBLIC_STATIC_STRING_IDENTIFIER, NoteEditor.smsTemplate);
  setResult(Activity.RESULT_OK, resultIntent);
        finish();
    }
}

Quick question, did you register the 2nd activity within your manifest? If not, that'll crash the application every time it would be invoked.

This question is closed. I accidentally found the answer to solve this error. It seems that 2 lines of my code is interfering with creating the 2nd activity. Thanks people ^^
