            app:cornerRadius="4dp"
            />

        <info.hoang8f.widget.FButton
            android:id="@+id/btnSignIn"
            android:text="Sign In"

            app:cornerRadius="4dp"
            />

    </LinearLayout>
</RelativeLayout>

Anyone knows what is going on? I did everything just like the tutorial.

The error is pointing to line #37 in your xml file, with the button that you have given an ID of "btnSignUp":

Error inflating class info.hoang8f.widget.FButton

Did you include this dependency in your gradle.build file?

dependencies {
    compile 'info.hoang8f:fbutton:1.0.5'
}

Also, make sure that you copied the FButton.java class from Github into your project. Finally, make sure that you've set the colors in your values folder.

Try to remove the buttonColor property in FButton because the real error is

Caused by: java.lang.UnsupportedOperationException: Can't convert value at index 1 to color: type=0x5
        at android.content.res.TypedArray.getColor(TypedArray.java:463)
        at info.hoang8f.widget.FButton.parseAttrs(FButton.java:116)
        at info.hoang8f.widget.FButton.<init>(FButton.java:52)

The error is from this code:

mButtonColor = typedArray.getColor(attr, R.color.fbutton_default_color);

and the error is:

java.lang.UnsupportedOperationException: Can't convert value at index 1 to color: type=0x5

So you should make sure that your color is correct. Maybe you didn't put # in the color ...
