<p>I am developing torch. I have developed widget with a single button. If you click on that button it turns on torch and if you click again it turns off torch. BUT when torch is ON and user pressed Power button to turn off screen it also turns off the torch. So I want to check if device has gone to sleep mode while torch was on, can someone help me ?</p> <p>here is my code to turn torch on and off in widget</p> <pre><code>public void onReceive(Context context, Intent intent) { Log.d("torchWidget", "onReceive"); final String action = intent.getAction(); if(AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) { final int appWidgetId = intent.getExtras().getInt( AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID); if(appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) { this.onDeleted(context, new int[] { appWidgetId }); } } else{ if(intent.getAction().equals(ACTION_WIDGET_RECEIVER)) { String msg = "null"; try{ msg = intent.getStringExtra("msg"); msg = "Flash Turned On"; } catch(NullPointerException e) { Log.e("Error", "msg = null"); } if(Constants.isFlashOnWidget){ Constants.isFlashOnWidget = false; Toast.makeText(context, "Flash turned OFF", Toast.LENGTH_SHORT).show(); Intent serviceIntent = new Intent(context.getApplicationContext(), BackgroundService.class); context.stopService(serviceIntent); } else { Constants.isFlashOnWidget = true; Intent serviceIntent = new Intent(context.getApplicationContext(), BackgroundService.class); context.startService(serviceIntent); } } super.onReceive(context, intent); } </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.
