    <p>I have an app that is very simple - it turns bluetooth on and off according to whether it's plugged in.</p> <p>The app right now is also very simple in terms of UI - there is 1 button on there, that allows you to turn bluetooth on and off if you want.</p> <p>I actually have this working, and have figured out how to update the button, but, I would like to update my UI only if the app is in the foreground - so, if I plug in my phone, and i'm NOT in my app, I <em>don't</em> want my app to pop up and update the UI - I only want the UI to change if the app was open when I plugged in the phone.</p> <p>I've tried the following code, and it does find the app in the running apps list, but it opens the app no matter what - i.e., it'll open the app and update my UI whether it was open before or not.</p> <pre><code> ActivityManager activityManager = (ActivityManager) context.getSystemService( Context.ACTIVITY_SERVICE ); List&lt;RunningAppProcessInfo&gt; appProcesses = activityManager.getRunningAppProcesses(); for(RunningAppProcessInfo appProcess : appProcesses){ if(appProcess.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND){ Log.i("Foreground App", appProcess.processName); if(appProcess.processName.equals("vermel.BluetoothOn")) { //update UI } } } </code></pre> <p>What am I doing wrong? Please bear in mind, I'm a fresh newbie in both Java and Android, and would highly appreciate details explanation, as opposed to a link to the android development documentation ;)</p> <p>Thanks for reading!</p>

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).
