Hi everyone:
When I was learning how to parse XML data described in the Android tutorial
(http://developer.android.com/training/basics/network-ops/xml.html), I found an
error in the sample file provided.
This error appears in the Android Manifest file and it is related with the
class name.
Those are the original lines:
<activity
android:name="com.example.networkusage.NetworkActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Since the default package is "com.example.android.networkusage", Android cannot
find the right class and the follow error appears:
08-14 16:28:24.435 E/AndroidRuntime(23879): java.lang.RuntimeException: Unable
to instantiate activity
ComponentInfo{com.example.android.networkusage/com.example.networkusage.NetworkActivity}:
java.lang.ClassNotFoundException: com.example.networkusage.NetworkActivity in
loader
dalvik.system.PathClassLoader[/data/app/com.example.android.networkusage-2.apk]
There are two way to fix this error. The first one is add the full path, which
is:
<activity
android:name="com.example.android.networkusage.NetworkActivity"
....
The second one is simply lfet the activity name (starts with dot):
<activity
android:name=".NetworkActivity"
....
