Android – HelloWebView Sample: java.lang.SecurityException: Permission Denial


I am trying to get the HelloWebView Sample up and running (as is, with no cuustomizations) found at

I continue to get java.lang.SecurityException: Permission Denial despite all efforts. In my mind this has got to be some fundamental lack of understanding on my part (I am a newbie) or something perhaps local to my development environment (Windows XP).

I have included my main.xml, AndroidManifest.xml, and console output below.

Things tried so far:

  • different api's (6,7)
  • adding/verifying (I think :)) that "uses-permission android:name="android.permission.INTERNET""
    has the correct syntax and location in my manifest.
  • wiping emulator
  • restarting eclipse, laptop etc.
  • disabling my internet security

Any help would be greatly appreciated.

Thank you.

my main xml is:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=""

my manifest file is:

<uses-permission android:name="android.permission.INTERNET" />

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".HelloWebView"
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
    <activity android:name=".HelloWebView" android:label="@string/app_name"


Actual console output:

Best Solution

You have two entries in your manifest file for your HelloWebView activity. Try removing the second.
