Floating Action Button causing error and crashing application

Question

When using the floating action button, my Android application crashes and throws an error. When I remove it, my application runs successfully, but I'd rather use the floating action button if I can.

This is my complete error log:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.supriya.hithere/com.example.supriya.hithere.MainActivity}: android.view.InflateException: Binary XML file line #32: Error inflating class android.support.design.widget.FloatingActionButton

Answer 1

Make sure you are using AppCompatActivity instead of Activity, and AppCompat theme.

<style name="Base.AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

If you are using any attributes like backgroundTint or borderWidth for the FAB, make sure you are using app namespace.

app:backgroundTint="@color/accent_color"
app:borderWidth="0dp"
