  <p>Here is manifest.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.appname.android"
      android:versionCode="3"
      android:versionName="1.0" &gt;
      &lt;uses-sdk android:minSdkVersion="7" /&gt;
      &lt;uses-permission android:name="android.permission.INTERNET"/&gt;
      &lt;application
          android:icon="@drawable/ic_launcher"
          android:label="@string/app_name"&gt;
          &lt;activity
              android:name=".ITCutiesReaderAppActivity"
              android:label="@string/app_name" &gt;
              &lt;intent-filter&gt;

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