    <p>*Solved I just had to publicly declare my webview variable for my back button class to work correctly. Thanks for the help</p> <p>I've got a unique setup with the webview class and everything I've googled I've gotten nowhere. </p> <p>I'm using buttons to launch webview's and I'm getting the issue that when I press the back button to return to my main app screen it will just kill the app. I have added some code in at the bottom to try and fix my issue but it has not worked.</p> <p>btw the below code has been updated to what is currently working for me.</p> <pre><code>package my.android.test; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.webkit.WebView; import android.widget.Toast; public class MobileAppActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } WebView wb; public void onMyButtonClick01(View view) { Toast.makeText(this, "Pay your dues here!", Toast.LENGTH_SHORT).show(); wb = new WebView(this); wb.loadUrl("http://www.link1.html"); setContentView(wb); } public void onMyButtonClick02(View view) { Toast.makeText(this, "Re-Sign here!", Toast.LENGTH_SHORT).show(); wb = new WebView(this); wb.loadUrl("http://www.link2.html"); setContentView(wb); } public void onBackPressed () { if(wb != null) { if(wb.canGoBack()) { wb.goBack(); } else { setContentView(R.layout.main); wb = null; } } else { super.onBackPressed(); } } } </code></pre>

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.

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