HelloWebView Sample: now using SDK 3 and getting killed

Question

Hey Folks,

Updated: I have now included the logcat file below. Looking at it it appears I am still having a permission problems (06-05 14:10:36.593) - I am guessing the same problem I am having with SDK 7

Well I was trying to get the HelloWebview example working with SDK 7 with no success (see HelloWebView Sample: java.lang.SecurityException: Permission Denial thread), so I decided just out of curiosity to back off to SDK3 to see if I could learn anything. I have been able to get all the "Layout" samples to work and decided to try something a little harder.

Unfortunately, I still cannot get the simple HelloWebView app to run. I no longer get a Permission Denial but now the app is getting killed.

Killed usually implies that there are not enough resources (memory etc.) for an application to run.... Any thoughts? Are there any other log files I can look at either on my computer or on the emulator?

The main.xml, manifest, and console output are below. Let me know if you need more information.

Thanks, Tim

main.xml:

 <?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>

mainfest file:

<uses-permission android:name="android.permission.INTERNET" />
<uses-sdk android:minSdkVersion="3" />

<application android:icon="@drawable/icon" android:label="@string/app_name">

    </activity>
    <activity android:name=".HelloWebView3" android:label="@string/app_name"

    </activity> 

</application>

Answer 1

There are any error messages you can look to. If you're using eclipse goto ddms perspective and open window logcat. (you can also directly display logcat without switching to the ddms perspective)
