onConfigurationChanged not called (Android 2.2)
<p>I already found a bunch of similar problems related with this topic and I knew the solution was to append "screenSize" to the android:configChanges attribute(please refer to <a href="http://stackoverflow.com/questions/5620033/onconfigurationchanged-not-getting-called">onConfigurationChanged not getting called</a> if you're interested). But it does not work for my situation.</p>

<p>My application was build on Android 2.2(API level 8) and the device is installed with 2.3.
Any clues? Thank you in advance.</p>

<pre><code>&lt;application android:icon="@drawable/icon" android:label="@string/app_name"
         android:debuggable="true"&gt;
        &lt;activity android:name="com.erlinyou.Erlinyou"
                  android:label="@string/app_name"                  
                  android:configChanges="orientation"&gt;                  
                  android:launchMode="singleInstance"&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;
&lt;/application&gt;
