    <p>My app consists of one activity. When i press back nothing happens, why is this? I thought it would kill the app. If I press home the app contines in the background as desired. It's just the back button that does nothing. What could I have done to affect this? </p> <p>I have read in the documentation:</p> <pre><code>public void onBackPressed () </code></pre> <p>Called when the activity has <strong>detected the user's press of the back key</strong>. The default implementation simply finishes the <strong>current activity</strong> but you can override this to do whatever you want.</p> <p>I have not overridden this.</p> <p>Here is something that has been mentioned, overriding keys:</p> <pre><code>public boolean dispatchKeyEvent(KeyEvent event) { if (event == null || event.getAction() == KeyEvent.ACTION_UP) { return false; } if(event.getKeyCode() == KeyEvent.KEYCODE_DEL){ mEntry.setOnFocusChangeListener(new OnFocusChangeListener(){ @Override public void onFocusChange(View v,boolean hasFocus){ /* When focus is lost check that the text field * has valid values. */ if (!hasFocus &amp;&amp; !mEntry.getText().toString().trim().equals("")) { mSession.appendToEmulator(cmdLeft, 0, cmdLeft.length); mSession.appendToEmulator(cmdErase, 0, cmdErase.length); Log.d(TAG, "in inner delete"); } else {mEntry.setText(" "); } } }); Log.d(TAG, "in delete in delete in delete in delete"); try { sendOverSerial("\b".getBytes("UTF-8")); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } } return super.dispatchKeyEvent(event); }; </code></pre> <p>Another snippet, from onCreate:</p> <pre><code>mEntry = (EditText) findViewById(R.id.term_entry); mEntry.setOnEditorActionListener(new TextView.OnEditorActionListener() { @Override public boolean onEditorAction(TextView v, int actionId, KeyEvent event) { /* Ignore enter-key-up events. */ if (event != null &amp;&amp; event.getAction() == KeyEvent.ACTION_UP) { return false; } </code></pre>

    3. COWell the code is a few thousand lines, I'm just wondering what ways do you know of that could have affected this? I suppose I can override it and make it finish, but it should already be doing that.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
