    <p>I am trying to avoid using onDestroy and want to keep this as simple as possible, but when I exit the program, I get a Force Close error. Not sure why. Here is the code for the main part of the application. Any suggestions?</p> <p><strong>Main Application Code</strong></p> <pre><code> public class Quotes extends Activity implements OnClickListener { ProgressDialog dialog; private WebView webview; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); WebView adsview = (WebView) findViewById(R.id.ads); adsview.getSettings().setJavaScriptEnabled(true); adsview.loadUrl("http://www.dgdevelco.com/quotes/androidad.html"); SharedPreferences SP = PreferenceManager.getDefaultSharedPreferences(getBaseContext()); String q = SP.getString("appViewType","http://www.dgdevelco.com/quotes/quotesandroidtxt.html"); String c = SP.getString("appRefreshRate","20"); webview = (WebView) findViewById(R.id.scroll); webview.getSettings().setJavaScriptEnabled(true); webview.setWebViewClient(new QuotesWebView(this)); webview.loadUrl(q); ScheduledExecutorService timer = Executors.newSingleThreadScheduledExecutor(); timer.scheduleAtFixedRate(new Runnable() { @Override public void run() { webview.reload(); } }, 10, Long.parseLong(c),TimeUnit.SECONDS); findViewById(R.id.refresh).setOnClickListener(this); } @Override public void onPause(){ super.onPause(); } @Override public void onResume(){ super.onResume(); } public void onClick(View v){ switch(v.getId()){ case R.id.refresh: webview.reload(); break; } } @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.menu, menu); MenuItem about = menu.getItem(0); about.setIntent(new Intent(this, About.class)); MenuItem preferences = menu.getItem(1); preferences.setIntent(new Intent(this, Preferences.class)); return true; } } </code></pre> <p><strong>LogCat</strong></p> <pre><code> 07-04 13:34:55.011: INFO/DevicePushListener(1415): Connection State Changed: NetworkInfo: type: WIFI[], state: CONNECTED/CONNECTED, reason: (unspecified), extra: (none), roaming: false, failover: false, isAvailable: true 07-04 13:34:55.011: WARN/WindowManager(1314): Attempted to add application window with unknown token HistoryRecord{40c40f50 com.dge.quotes/.Quotes}.

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).
