    <p>When I compile it, there is no error showing in the Eclipse IDE. But When I run it, it keeps crashing. Why? </p> <p>I don't know what to do since there are no errors showing. It just run and crush before it starts.</p> <pre><code>public class MainActivity extends Activity implements OnClickListener, OnInitListener { private TextToSpeech tts; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); tts = new TextToSpeech(this, this); this.initializeTextToSpeech("Hello World"); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } @Override protected void onDestroy() { if (tts != null) { tts.stop(); tts.shutdown(); } super.onDestroy(); } @Override public void onInit(int status) { // TODO Auto-generated method stub if (status == TextToSpeech.SUCCESS) { tts.setLanguage(Locale.getDefault()); } else { tts = null; Toast.makeText(this, "Failed to initialize TTS engine.", Toast.LENGTH_SHORT).show(); } Log.d("onINIT", "started"); } @Override public void onClick(View v) { // TODO Auto-generated method stub } public void initializeTextToSpeech(String str) { if (tts != null) { String text = str; if (text != null) { if (!tts.isSpeaking()) { tts.speak(text, TextToSpeech.QUEUE_FLUSH, null); } } } } } </code></pre> <p>Here my LogCat:</p> <pre><code>12-21 01:53:07.698: I/Process(1467): Sending signal.

    1. COShow us your LogCat. That's how you debug something like this. It is crashing because it is executing code that is technically correct (can compile), but will still crash your app.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
