title: android multiple activity declaration in manifest
body: <p>I have a main activity. From it, I am calling 2 other sub activities called FacebookLogin and Twitterlogin. I am using the following code in AndroidManufest.xml: </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.examples.Kikin" android:versionCode="1"
  android:versionName="1.0"&gt;
  &lt;!-- THIS IS THE BEGINNING OF SHARING LINKS FROM THE BROWSER --&gt;
  &lt;application android:icon="@drawable/kikinlogo"
      android:label="@string/app_name" android:debuggable="true"&gt;
      &lt;activity android:name=".Kikin" android:label="@string/app_name"&gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.MAIN" /&gt;
              &lt;category android:name="android.intent.category.LAUNCHER"/&gt;
          &lt;/intent-filter&gt;
          &lt;intent-filter android:label="@string/app_name"&gt;
              &lt;action android:name="android.intent.action.SEND" /&gt;
              &lt;category android:name="android.intent.category.DEFAULT" /&gt;
              &lt;data android:mimeType="text/plain" /&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
      &lt;activity android:name=".FacebookLogin" android:label="@string/app_name"&gt;
          &lt;intent-filter android:label="@string/app_name"&gt;
              &lt;action android:name="android.intent.action.SEND" /&gt;
              &lt;category android:name="android.intent.category.DEFAULT" /&gt;
          &lt;!--    &lt;data android:mimeType="image/png" /&gt; --&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
      &lt;activity android:name=".TwitterLogin" android:label="@string/app_name"&gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.VIEW"&gt;&lt;/action&gt;
              &lt;category android:name="android.intent.category.DEFAULT"&gt;&lt;/category&gt;
              &lt;category android:name="android.intent.category.BROWSABLE"&gt;&lt;/category&gt;
              &lt;data android:scheme="yourapp" android:host="twitt"&gt;&lt;/data&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
  
  &lt;/application&gt;
  &lt;uses-sdk android:minSdkVersion="8" /&gt;
  &lt;uses-permission android:name="android.permission.READ_CONTACTS" /&gt;
  &lt;uses-permission android:name="android.permission.INTERNET" /&gt;
  </code></pre>
  
  <p> 
  Am i doing it right?
  Should i nest the FacebookLogin and TwitterLogin activities in the main <strong><em></strong> activity?
  The aforesaid 2 classes are in the package com.examples.<strong></em></strong>.
  <strong>*</strong> is the same wherever used.</p>
