    <p>I've managed this in an app by using a SharedPreferences value as to whether the activity is visible or not:</p> <pre><code> @Override protected void onStart() { super.onStart(); SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this); SharedPreferences.Editor editor = preferences.edit(); editor.putBoolean("RVisibleNow",true); editor.commit(); } </code></pre> <p>and</p> <pre><code> @Override protected void onStop() { SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this); SharedPreferences.Editor editor = preferences.edit(); editor.putBoolean("RVisibleNow",false); editor.commit(); super.onStop(); } </code></pre> <p>then, yes, using a BroadcastReceiver such as:</p> <pre><code>private BroadcastReceiver receiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { String theRow = intent.getStringExtra(GCMIntentService.MESSAGE); String theQuery="SELECT * FROM listdata WHERE _id ='" + theRow + "'"; String action = intent.getAction(); if(action.equals("com.you.yourapp.UpdateList")){ ... </code></pre> <p>Oh, and in your GCM service:</p> <pre><code>public static final String BROADCAST = "com.you.yourapp.UpdateList"; public static final String MESSAGE = "com.you.yourapp.GCMIntentService.MESSAGE"; ... if(RVisibleNow){ sendBroadcast(context, message, insertOrUpdate); }else{ generateNotification(context, message, insertOrUpdate); } </code></pre> <p>In my case, with a lot of omitted code, my sendBroadcast looked like:</p> <pre><code>private void sendBroadcast(Context context, String message, String whichFunction){ String putExtraParam = "something"; Intent in = new Intent(BROADCAST); in.putExtra(MESSAGE, putExtraParam); context.sendBroadcast(in); } </code></pre> <p>Hope this helps!</p>

    1. COI'm confused about the sendBroadcast() method. I see that it only takes 2 arguments (Intent, String), but you have given 3. Can you clarify this? What is the intent supposed to be and what is the String?

    3. COThe sendBroadcast method is just my own way of passing variable values. My response has more to do with a) setting a preferences value as to whether or not your activity is visible; and then b) either generating a notification or updating your UI based on that.

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).
