    <p>I want to enable/disable the data connection programmatically. I've used the following code:</p> <pre><code>void enableInternet(boolean yes) { ConnectivityManager iMgr = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE); Method iMthd = null; try { iMthd = ConnectivityManager.class.getDeclaredMethod("setMobileDataEnabled", boolean.class); } catch (Exception e) { } iMthd.setAccessible(false); if(yes) { try { iMthd.invoke(iMgr, true); Toast.makeText(getApplicationContext(), "Data connection Enabled", Toast.LENGTH_SHORT).show(); } catch (IllegalArgumentException e) { // TODO Auto-generated catch block dataButton.setChecked(false); Toast.makeText(getApplicationContext(), "IllegalArgumentException", Toast.LENGTH_SHORT).show(); } catch (IllegalAccessException e) { // TODO Auto-generated catch block Toast.makeText(getApplicationContext(), "IllegalAccessException", Toast.LENGTH_SHORT).show(); e.printStackTrace(); } catch (InvocationTargetException e) { // TODO Auto-generated catch block dataButton.setChecked(false); Toast.makeText(getApplicationContext(), "InvocationTargetException", Toast.LENGTH_SHORT).show(); } } else { try { iMthd.invoke(iMgr, true); Toast.makeText(getApplicationContext(), "Data connection Disabled", Toast.LENGTH_SHORT).show(); } catch (Exception e) { dataButton.setChecked(true); Toast.makeText(getApplicationContext(), "Error Disabling Data connection", Toast.LENGTH_SHORT).show(); } } } </code></pre> <p>It's working without any errors in the emulator but, I'm getting "InvocationTargetException" when I try to run it on a real device. I'm using API level 8 to build the application.</p>

Guidance
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).
