Back from launcher icon in ActionBar

Question

I am creating ActionBar using android-support-v7-appcompat. In action bar I have up navigation from logo enabled and its working fine on device with API level 17. But when I run my app on API level 10 device its not working. Please help me. Thanks in advance.

Using following code in activity-

private ActionBar ab;
ab = getSupportActionBar();
ab.setDisplayHomeAsUpEnabled(true);

In Manifest file-

<activity
 android:name=".History"
 android:screenOrientation="portrait"
 android:theme="@style/Theme.Styled"
 android:parentActivityName=".MainActivity">

ActionBar is not supported for below API 11 level.Thats why you are getting error.Read this documentation.

To make your code work in lower version, you have to use android-support-v7-appcompat instead of ActionBar.Read the below blog about how to migrate from ActionBar to android-support-v7-appcompat.

EDIT : you can download and setup the support library as mentioned here

Below is my explanation based on your updated code,

-To enable up navigation in beginning in Android 4.1 (API level 16), you can declare the logical parent of each activity by specifying the android:parentActivityName attribute in the element.

-If your app supports Android 4.0 and lower, include the Support Library with your app and add a <meta-data> element inside the . Then specify the parent activity as the value for android.support.PARENT_ACTIVITY, matching the android:parentActivityName attribute like below example,

 <activity
        android:name="com.example.myfirstapp.DisplayMessageActivity"
        android:label="@string/title_activity_display_message"
        android:parentActivityName="com.example.myfirstapp.MainActivity" >
        <!-- Parent activity meta-data to support 4.0 and lower -->
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.example.myfirstapp.MainActivity" />
    </activity>
