HelloWebView Sample: java.lang.SecurityException: Permission Denial

Question

Hey Folks,

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

http://developer.android.com/resources/tutorials/views/hello-webview.html

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. Tim

my main xml is:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<WebView
    android:id="@+id/webview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>
</LinearLayout> 

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"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".HelloWebView" android:label="@string/app_name"
 android:theme="@android:style/Theme.NoTitleBar">
    </activity> 

</application>

Actual console output:

Answer 1

Hi Tim this exception is related to API Version, for example I use Android 1.5 so I add to my AndroidManifest.xml file

<uses-sdk android:minSdkVersion="3" />

check your messages output...

[2010-06-04 07:57:34 - HelloWebView] WARNING: Application does not specify an API level requirement! 
[2010-06-04 07:57:34 - HelloWebView] Device API version is 7 (Android 2.1)
