Home button missing in ActionBar

Question

I can't see the home button (icon) in the ActionBar when I create a completely new project in eclipse (Activity with ActionBar extends android support v7 app ActionBarActivity). No changes were made in the project. I'm using the new Android 5.0 sdk.

There is also no change when I set for instance

getSupportActionBar().setDisplayShowHomeEnabled(true)

Generated manifest, ic_launcher is in the correct directory:

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

<uses-sdk
    android:minSdkVersion="9"
    android:targetSdkVersion="21" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

Answer 1

I reinstalled the eclipse and android sdk again. Now it works.
