Error:(105) Error parsing XML: unbound prefix

Question

i got 3 errors on my projects :

First and Second Error :

First: Error:(105) Error parsing XML: unbound prefix

<com.melnykov.fab.FloatingActionButton
    android:id="@+id/fabButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginBottom="24dp"
    android:layout_marginRight="24dp"
    android:src="@drawable/ic_action_new"
    app:fabSize="normal"
    app:layout_anchor="@id/profileListView"
    android:elevation="2dp"
    android:layout_marginEnd="41dp"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true"
    fab:fab_colorNormal="@color/colorFloatActionButton"
    fab:fab_colorPressed="@color/colorFloatActionButton"
    fab:fab_colorRipple="@color/colorRipple" />

Second Error : Error:(105) Error parsing XML: unbound prefix

<com.melnykov.fab.FloatingActionButton
    android:id="@+id/fabButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginBottom="24dp"
    android:layout_marginRight="24dp"
    android:src="@drawable/ic_action_new"
    app:fabSize="normal"
    app:layout_anchor="@id/profileListView"
    android:elevation="2dp"
    android:layout_marginEnd="41dp"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true"
    fab:fab_colorNormal="@color/colorFloatActionButton"
    fab:fab_colorPressed="@color/colorFloatActionButton"
    fab:fab_colorRipple="@color/colorRipple" />

Third Errror :

Error:Execution failed for task ':app:processDebugResources'.

com.android.ide.common.process.ProcessException: Failed to execute aapt

I think the package name is wrong for the Floating Action Button, check it and change the package name accordingly — Rakshit Nawani, Sep 27 '16 at 18:59

The direct errors indicate undeclared namespace prefixes. Make sure you have the following on the root element of your XML file:

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

(Or choose one of app and fab and use consistently.)

Note, however, that com.melnykov.fab.FloatingActionButton is deprecated.

You really should use FloatingActionButton instead.
