Unable to use material design library

Question

I would like to import a library with material elements to my project. So as in the Github instruction mentioned I have added that dependency to my grade file:

dependencies {
   compile 'com.github.rey5137:material:1.2.1'
}

Gradle syncing after that. and in the next step I have added the xml to my layout:

  <com.rey.material.widget.Spinner
            style="@style/Material.Widget.Spinner"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:rd_style="@style/Material.Drawable.Ripple.Wave"/>

Running the app gives me the issue:

Binary XML file line #35: Binary XML file line #35: Error inflating class com.rey.material.widget.Spinner

What else should I do to import that library correctly ? I have no idea what I have missed.

My xml layout file:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

    android:orientation="vertical">

Answer 1

Try this:

Open build.gradle (Module: app)

Change compile 'com.github.rey5137:material:1.2.1' to compile 'com.github.rey5137:material:1.2.1.6-SNAPSHOT'

Then after apply plugin: 'com.android.application' , put repositories { maven { url "https://oss.sonatype.org/content/repositories/snapshots" } }

Then make a Gradle sync as suggested by Android Studio.
