Android How to check device/tablet support calling functionality
<p>In my app there is a calling functionality. On click of "Call" button, app will launch the phone dialer with phone number. </p>

<p>Now if any of the device/tablet is not having the calling functionality, in that case i want to check this</p>

<pre><code>if(isSupportCalling) 
      //launch dialer
else 
     //show message
</code></pre>

<p>inorder to avoid any application crash.</p>

<p>As this permission will only allow android play to make it visible and able to download/install the app on device/tablet which don't support calling functionality.</p>

<pre><code>&lt;uses-feature 
        android:name="android.hardware.telephony" 
        android:required="false"/&gt;
</code></pre>

<p>As i had seen very few threads on SO related to this, but didn't find a reliable way to this.</p>
