Error inflating class com.sothree.slidinguppanel.SlidingUpPanelLayout

Question

I'm using umano's SlidingUpPanel library in my project, but when I tried to run the app, an InflateException was raised.

android.view.InflateException: Binary XML file line #1: Error inflating class com.sothree.slidinguppanel.SlidingUpPanelLayout

This is my layout

<com.sothree.slidinguppanel.SlidingUpPanelLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/bg_main"
    android:layout_gravity="bottom">

    <CalendarView
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <!-- other layout -->
    </RelativeLayout>
</com.sothree.slidinguppanel.SlidingUpPanelLayout>

And this is my gradle dependencies

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile('com.google.android.gms:play-services:6.1.71') {
        exclude module: 'support-v4'
    }
    compile 'com.sothree.slidinguppanel:library:3.0.0'
    compile 'com.google.guava:guava-collections:r03'
    compile 'com.roomorama:caldroid:1.1.8'
}

What did I do wrong?

As per earlier comment:

Based on what I can see, it looks like you may have forgotten to set the mandatory attribute android:gravity="bottom|top" (choose one), or perhaps you mixed it up with the currently set android:layout_gravity="bottom" attribute?

The correct gravity attribute should be set somewhat like this:

<com.sothree.slidinguppanel.SlidingUpPanelLayout 
    ...
    android:gravity="bottom"
    ...
>

...

</com.sothree.slidinguppanel.SlidingUpPanelLayout>
