    <p><br> i want my application to play a sound whenever the user makes an input the EditText field. Hopefully this will create the illusion that the keyboard makes the sound whenever a key is pressed.</p> <p>My code for this specific event lookes like this:</p> <pre><code>package com.textField.android; </code></pre> <p>public class textField extends Activity {</p> <pre><code>@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final EditText edittext = (EditText) findViewById(R.id.edittext); final MediaPlayer mp = MediaPlayer.create(getBaseContext(), R.raw.pistol); edittext.addTextChangedListener(new TextWatcher() { public void afterTextChanged(Editable s) { } public void beforeTextChanged(CharSequence s, int start, int count, int after) { } public void onTextChanged(CharSequence s, int start, int before, int count) { mp.start(); mp.setOnCompletionListener(new OnCompletionListener() { @Override public void onCompletion(MediaPlayer mp) { mp.release(); } }); } </code></pre> <p>}); } }</p> <p>I can install and open the application just fine, and i can enter ONE letter and it plays the sound, but when pressing a second letter the application crashes. I don't know what's wrong. Rotating my device plays the sound aswell no matter how many times i do it. So when rotating back it plays the sound again. But then pressing a key the application crashes WITHOUT playing the sound.<br> Can someone help me get this right? That would be very much appreciated :)</p>

    1. COTry to add some LogCat output from the crash. This is vital for finding out what causes the crash.

    3. COAhh, LogCat is so so so important! It will list the exceptions you are getting that led to your crash. http://stackoverflow.com/questions/3280051/how-to-enable-logcat-in-eclipse covers enabling LogCat. Then you can check the LogCat window when you crash - it even allows you to filter by E (Exceptions or Errors, not sure). Someone can probably figure out this issue without LogCat output, but you will want it set up for later no matter what. http://developer.android.com/reference/android/util/Log.html is worth checking out too.

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.
