How to dismiss/close class 0 message dialogs in Android
<p>Is there any way to dismiss/close/cancel or at least <em>programatically/automatically</em> anwer the <strong>class 0 messages</strong> also called <strong>flash messages</strong> in android?  </p>

<p>Class 0 Message dialog:</p>

<p>I have gone through the following forums but no definitive answer is given.</p>

<ul>
<li>androidforums.com/threads/class-0-zero-messages.331720/</li>
<li>www.droidforums.net/threads/can-you-block-class-0-messages.281093/</li>
</ul>

<p>The following software (<strong>Notification History Pro</strong>) claims to have solved this problem.</p>

</ul>

<p>I have used the free version but it doesn't provide the "automatically close class 0/ flash message dialog" feature.
I have checked every possible answer on stackoverflow.com but they don't provide the answer to my question. </p>

<p>I have also tried the following answers on dismissing the <strong>USSD/system dialogs</strong> on android with no avail. It only works for USSD/system dialogs but not for "<strong>class 0 messages</strong>".</p>

</ul>

<p>Any help will be highly appreciated.</p>

<p><strong>UPDATE</strong>: The pro version of the Android application I referenced solves the problem. That said, I need to implement the feature in my own application. </p>
