Android java.lang.RuntimeException: Unable to instantiate activity ComponentInfo
<p>Ok guys this doesn't make sense to me at all and I don't understand why I am getting this error in my app. I have registered the activity class in the android manifrest xml.. </p>

<pre><code>java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.mobile.batteryhelper/com.mobile.batteryhelper.Battery}:
java.lang.ClassNotFoundException: Caused by: java.lang.ClassNotFoundException: com.mobile.batteryhelper.Battery in loader dalvik.system.PathClassLoader[/mnt/asec/com.mobile.batteryhelper-1/pkg.apk]
</code></pre>

<p>Here is the androidmanifest.xml. Yes the .Battery class extends Activity also.</p>

<pre><code>&lt;application android:icon="@drawable/icon" android:label="@string/app_name"&gt;
    &lt;activity android:name=".Battery"
              android:label="@string/app_name"
               android:screenOrientation="portrait"&gt;
        &lt;intent-filter&gt;
            &lt;action android:name="android.intent.action.MAIN" /&gt;
            &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
        &lt;/intent-filter&gt;
    &lt;/activity&gt;
</code></pre>
