Inside your activity

getSupportActionBar().setDisplayHomeAsUpEnabled(true); getSupportActionBar().setDisplayShowHomeEnabled(true);

@Override
public boolean onSupportNavigateUp() {
 onBackPressed();
 return true;
}

In the manifest xml, set this attribute for the activity from where you want to navigate up:

android:parentActivityName="com.example.MainActivity"

Set the value to the activity you want to navigate back to.

Add this meta data tag for supporting android versions 4.0 or lower:

<meta-data
        android:name="android.support.PARENT_ACTIVITY"
        android:value="com.example.myfirstapp.MainActivity" />

For information at: Providing Up Navigation

Note: Since you have used ActionBar object, make sure you are using the right one, that is android.support.v7.app.ActionBar

try using a custom toolbar in activity.xml

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbarLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

1- set your toolbar

Toolbar toolbar = findViewById(R.id.toolbar);

2- setup your icon

if (toolbar != null) {
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);

}

3- override this method

@Override
public boolean onSupportNavigateUp() {
    onBackPressed();
    return true;
}
