copied!<blockquote> <p>once the user selects particular mail client,I need to show his inbox</p> </blockquote> <p>There is no standard <code>Intent</code> structure for showing an email inbox. There are many, many email apps for Android, each of which can do this however they wish.</p> <p>The best you can hope to do is:</p> <ul> <li><p>Create an <code>ACTION_SENDTO</code> <code>Intent</code> with a <code>mailto:</code> <code>Uri</code></p></li> <li><p>Use that <code>Intent</code> with <code>PackageManager</code> and <code>queryIntentActivities()</code> to find all activities that support this, and hope that they are actually from email clients</p></li> <li><p>Find out the applications associated with those activities, from the <code>ResolveInfo</code> you get back from <code>queryIntentActivities()</code></p></li> <li><p>Use <code>getLaunchIntentForPackage()</code> on <code>PackageManager</code> to find some likely "front door" activity for each of the applications</p></li> <li><p>Create your own chooser-style dialog to allow the user to choose one of those applications</p></li> <li><p>Call <code>startActivity()</code> on the <code>Intent</code> they chose</p></li> </ul> <p>However:</p> <ul> <li><p>This may include non-email apps, as I am welcome to write an app that offers to support <code>mailto:</code> <code>Uri</code> values with <code>ACTION_SENDTO</code></p></li> <li><p>The "front door" activities of these apps are not necessarily the inbox</p></li> </ul> <blockquote> <p>he can select the particular email and he can send that email</p> </blockquote> <p>I have no idea what this means.</p> <blockquote> <p>To open email clients i have used this particular code</p> </blockquote> <p>Note that your code has two flaws:</p> <ol> <li><p>You are using an invalid MIME type (plain text is <code>text/plain</code>, not <code>plain/text</code>)</p></li> <li><p>You are not supplying a prompt for the chooser</p></li> </ol>
