How to merge two applications?
<p>I am developing an Answering Machine application.</p>

<p>Basically it has to automatically accept the call, give a voice message and start recording the call.</p>

<p>I have designed an application to automatically answer to calls and another application to record calls. Individually both the apps work fine. But after i merged them the application crashes.</p>

<p>I saw a an example here :<a href="http://stackoverflow.com/questions/7950677/combine-2-android-apps">Combine 2 android apps</a>. I merged the apps same way but still the application crashes.</p>

<p>How can I properly merge my apps?</p>
