And this is my AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

        </intent-filter>
     </activity>
    </application>

    </manifest>

And this is my activity.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/RelativeLayout1"
android:layout_width="match_parent"

android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.sagarappproject.MainActivity" >

<TextView
    android:id="@+id/TextView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"

    android:layout_marginLeft="32dp"
    android:layout_marginTop="32dp"
    android:text="@string/hello_world" />
</RelativeLayout>

Answer 1

It seems others have had the same problem. Change android:targetSdkVersion to 19 , as shown here

Answer 2

See the answer here .

It states that

You cannot combine swipe dismissal and the action bar

as an sdk problem.

The answer tells you to change the target sdk version to 19

It also points out that

Do not mess up with API Level and Platform, as Android Virtual Device. With Level 19+ and Platform 4.2.2+ set on ADV everything runs as it should.

Answer 3

The problem is that your emulator uses 4.4W API wich is android Wear. This means you cannot use the ActionBar on that emulator, becuase it uses the Wear framework. Try changing the emulator API level to 19 or 21. It should work then.
