this main_activity_actions.xml

<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@+id/action_add" android:icon="@drawable/ic_add" android:title="add" android:showasaction="always" /> </menu>

please help cant figure out what's wrong !

since activity extends actionbaractivity using appcompat back upwards library.

so alter

<menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:yourapp="http://schemas.android.com/apk/res-auto" > <item android:id="@+id/action_add" android:icon="@drawable/ic_add" android:title="add" yourapp:showasaction="always" /> ... </menu>

quoting docs

notice showasaction attribute above uses custom namespace defined in tag. necessary when using xml attributes defined back upwards library, because these attributes not exist in android framework on older devices. must utilize own namespace prefix attributes defined back upwards library.
