Pop up dialog no matter what the user is doing

I hope this isn't a duplicate of a similar question but haven't been able to find anything that helped me.

I'm creating a simple egg timer, and it works very well. Though I am struggling one thing. When the timer runs out, an alarm starts and an activity shown as a dialog pops up. Though this happens only if the app i open. If I open another app and the alarm goes off nothing happens.

So my question is, how do I make the dialog pop up no matter what the user is doing?

At the moment my method for displaying the dialog looks like this:

private void ShowTimesUp(){
    Intent dialogIntent = new Intent(getBaseContext(), TimesUpDialog.class);
    dialogIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivityForResult(dialogIntent, 1);
}

and the manifest looks like this:

    <activity android:name=".Home"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>

    <activity android:name=".TimesUpDialog" android:theme="@android:style/Theme.DeviceDefault.Dialog"></activity>

Try this: 

public static final int TIMEOUT = 60 * 1000;

...

Intent dialogIntent = new Intent(getBaseContext(), TimesUpDialog.class);
    dialogIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

PendingIntent intent = PendingIntent.getActivity(YourApplication.getInstance().getBaseContext(), 0,
            dialogIntent, dialogIntent.getFlags());

AlarmManager mgr = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC, System.currentTimeMillis() + TIMEOUT, intent);

I think you will not need any other timer logic.

P.S.: I did not test this, hope it helps.

Edit: a possible solution for the question mentioned in below comment

Now I am just wondering if it is possible to get a result from the intent started by the AlarmManager?

The above code should be changed to this: 

Intent startApplicationIntent = new Intent(getBaseContext(), MainActivity.class);
    dialogIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startApplicationIntent.putExtra(START_DIALOG, true);

PendingIntent intent = PendingIntent.getActivity(YourApplication.getInstance().getBaseContext(), 0,
            startApplicationIntent, startApplicationIntent.getFlags());

AlarmManager mgr = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC, System.currentTimeMillis() + TIMEOUT, intent);

Now in your MainActivity's onStart() method you could do the following: 

boolean startDialog = getIntent().getBooleanExtra(START_DIALOG, false);
if (startDialog) {
    Intent dialogIntent = new Intent(MainActivity.this, TimesUpDialog.class);
    startActivityForResult(dialogIntent, REQUEST_CODE_CONSTANT);
}

Where START_DIALOG is a String constant defining an intent extra value's key and MainActivity is the Launcher activity.

Hope this works for you.
