AndroidManifest XML file

Adding Activity to Android Project


I followed the Tab Layout Tutorial on Android Developers (http://developer.android.com/resources/tutorials/views/hello-tabwidget.html), but couldn't get the tabs to work.


When you add activity classes to the project, you must and the activity to the android manifest (AndroidManifest.xml) file.


Example:
public class SecondTab extends Activity {
...
}


must have the following line in the AndroidManifest.xml file

<activity android:name=".SecondTab" />

Adding uses-permission


Must be in the manifest portion of the xml file


Example:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.???.???"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
    ...
    </application>
    <uses-permission android:name="android.permission.INTERNET" />
</manifest>
