One android app to control another app
<p>I currently have an android app in the market which has a free and pro version of the app. The pro app doesn't provide any functionality it is just an unlock app which enables extra features from within the pro app. </p>

<p>What I want to be able to is to allow the user from the free app to enable SMS messaging that when a certain message arrives it wipes the content of the free app. However, I do not want to enable the SMS permission on the free as this may put people off as it is a password app, so what I want to do is the following:</p>

<ol>
<li>The user, from the free app enables the sms check</li>
<li>The pro app has permission to check SMS messages and if the app settings from the free app enables this sms check, then the pro app checks for when a message arrives with particular criteria</li>
<li>If the pro app finds the matching critera, then the pro triggers the free app to remove all content of the app, i.e. all data within the apps preferences and database.</li>
</ol>

<p>Is this possible and if so how could it be done, couldn't find anything on Google, probably using the incorrect keywords!</p>
