Answer 1

ANDROID STUDIO

if you are using ANDROID STUDIO...... use this fix

add

xmlns:compat="http://schemas.android.com/tools"

in menu tag instead of

xmlns:compat="http://schemas.android.com/apk/res-auto "

in menu tag.

Answer 2

you must choose an API 14 with version of 4.0 or grater because any version below 4.0 does not contain in its package the showAsAction attribute

Answer 3

I had this problem when I forgot to add appcompat-v7:+ to my project dependencies. You can do it like this in build.gradle:

dependencies {
  compile 'com.android.support:appcompat-v7:+'
}

And this is because I had the following in my menu.xml:

xmlns:app="http://schemas.android.com/apk/res-auto"

and

app:showAsAction="never"

When I removed the xmlns:app namespace and just used android:showAsAction="never", I didn't need the appcompat-v7 library anymore.

Answer 4

Are you sure you are looking in the right *.xml file? You seem to look for "showAsAction" in layout xmls, but it's parameter for the menu. Look rather into .../menu/your_activity.xml

The problem you are dealing with is connected with using target less than 4.0 and/or API less than 14.

So,

a) change those parameters,

b) change the value of showAsAction from "never" to "ifRoom".

Answer 5

This happens if you have used the resourceidentifier "ShowAsAction" in your XML. This feature is available only from ver11 i guess. If you are trying to run the same on a lower API version this errror is produced. SOLUTION ->> Right click the project > Properties > Android> Build Target > Choose something greater than API 11

Answer 6

The right answer is to use

android:showAsAction="ifRoom"

instead where android is

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