title: Why android:installLocation="internalOnly" is not working?
body: <p>In my manifest file I have given <code>installLocation="internalOnly"</code> in the manifest tag and below in my upper part of manifest: </p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.flexsin.classified"
  android:versionCode="1"
  android:versionName="1.0" 
  android:installLocation="internalOnly" &gt;

              &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;

  <p>I have send a mail with APK and when i clicked on Install button, it shows me, 
      " The  attachment could not be downloaded because the SD card is missing or not
      mounted".
      My question is why it is showing this message, when I want my apk to install on Phone
      memory.</p>
  
  <pre><code>Phone mem available space=50Mb
  Phone model: Samsung GT-S5570
  </code></pre>
  
  <p>PS: device does not have SD card. </p>
