Question

I am building an app with Android 2.3.3 API. I need to recognize the change in orientation and perform some action. So I added the following in Android Manifest,

android:configChanges="orientation|keyboardHidden

And I override the method

public void onConfigurationChanged(Configuration newConfig)

It works perfect on Android 2.3.3. But when I install the same app (built with 2.3.3 API) on a 4.1.2, onConfigurationChanged() is not invoked. I searched online for solution and people suggest to add the following in android manifest.

 android:configChanges="orientation|keyboardHidden|screenSize"

If I build the app with above statement and built with 4.1.2 API, It works perfect on 4.1.2 device. But I cannot install it on 2.3.3. 2.3.3 API doesn’t have “screenSize” option. So to support both, what should I do?

Thanks, Karthik

Hi Look at mine AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="10" 
    android:maxSdkVersion="16"/>

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity 
        android:name=".ConfigrationTask"
        android:configChanges="orientation|keyboardHidden"
        >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>

    </activity>
</application>
