I am trying to include this Slider library into my code.

When I added this to my layout:

<SlidingLayer
    android:id="@+id/slidingLayer1"
    android:layout_width="match_parent"
    android:layout_height="@dimen/layer_height"
    android:elevation="2dip"
    android:layout_above="@+id/linearLayout"
    android:layout_alignParentStart="true">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/primary_light">

        <WebView
            android:id="@+id/authWebView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:gravity="center"
            android:drawablePadding="15dip"
            android:paddingBottom="80dp"
            android:textSize="17sp"
            android:textColor="@color/primary_text"/>

        <Button
            android:id="@+id/buttonClose"
            style="@style/ButtonRed"
            android:onClick="buttonClicked"
            android:layout_marginBottom="60dp"
            android:layout_alignParentBottom="true"
            android:layout_centerHorizontal="true"
            android:text="@string/close_button_container"/>
    </RelativeLayout>
</SlidingLayer>

and including the 

private SlidingLayer mSlidingLayer;

then, in onCreate():

setContentView(R.layout.activity_main);
initSlider();

and further in the initSlider() method:

private void initSlider() {
    mSlidingLayer = (SlidingLayer) findViewById(R.id.slidingLayer1);
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
    setupSlidingLayerPosition(prefs.getString("layer_location", "bottom"));
    setupSlidingLayerTransform(prefs.getString("layer_transform", "none"));
    setupShadow(prefs.getBoolean("layer_has_shadow", false));
    setupLayerOffset(prefs.getBoolean("layer_has_offset", false));
    setupPreviewMode(prefs.getBoolean("preview_mode_enabled", false));
}

whereas the setup* method within the initSlider() was taken from here.

But my app crashes at setcontentview in the onCreate() with this error message:

E/AndroidRuntime: FATAL EXCEPTION: main Process: com.mysliderapp, PID: 22831 java.lang.RuntimeException: Unable to start activity ComponentInfo{com.mysliderapp/com.mysliderapp.MainActivity}: android.view.InflateException: Binary XML file line #46: Error inflating class SlidingLayer at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2205) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2255) at android.app.ActivityThread.access$800(ActivityThread.java:142) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1203) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:136) at android.app.ActivityThread.main(ActivityThread.java:5118) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:515) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:794) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:610) at dalvik.system.NativeStart.main(Native Method) Caused by: android.view.InflateException: Binary XML file line #46: Error inflating class SlidingLayer at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:707) at android.view.LayoutInflater.rInflate(LayoutInflater.java:755) at android.view.LayoutInflater.inflate(LayoutInflater.java:492) at android.view.LayoutInflater.inflate(LayoutInflater.java:397) at android.view.LayoutInflater.inflate(LayoutInflater.java:353) at com.android.internal.policy.impl.PhoneWindow.setContentView(PhoneWindow.java:319) at android.app.Activity.setContentView(Activity.java:1973) at com.mysliderapp.MainActivity.onCreate(MainActivity.java:99) at android.app.Activity.performCreate(Activity.java:5275) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1087) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2169) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2255)  at android.app.ActivityThread.access$800(ActivityThread.java:142)  at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1203)  at android.os.Handler.dispatchMessage(Handler.java:102)  at android.os.Looper.loop(Looper.java:136)  at android.app.ActivityThread.main(ActivityThread.java:5118)  at java.lang.reflect.Method.invokeNative(Native Method)  at java.lang.reflect.Method.invoke(Method.java:515)  at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:794)  at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:610)  at dalvik.system.NativeStart.main(Native Method)  Caused by: java.lang.ClassNotFoundException: Didn't find class "android.view.SlidingLayer" on path: DexPathList[[zip file "/data/app/com.mysliderapp-2.apk"],nativeLibraryDirectories=[/data/app-lib/com.mysliderapp-2, /vendor/lib, /system/lib]] at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56) at java.lang.ClassLoader.loadClass(ClassLoader.java:497) at java.lang.ClassLoader.loadClass(ClassLoader.java:457) at android.view.LayoutInflater.createView(LayoutInflater.java:559) at android.view.LayoutInflater.onCreateView(LayoutInflater.java:652) at com.android.internal.policy.impl.PhoneLayoutInflater.onCreateView(PhoneLayoutInflater.java:66) at android.view.LayoutInflater.onCreateView(LayoutInflater.java:669) at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:694) at android.view.LayoutInflater.rInflate(LayoutInflater.java:755)  at android.view.LayoutInflater.inflate(LayoutInflater.java:492)  at android.view.LayoutInflater.inflate(LayoutInflater.java:397)  at android.view.LayoutInflater.inflate(LayoutInflater.java:353)  at com.android.internal.policy.impl.PhoneWindow.setContentView(PhoneWindow.java:319)  at android.app.Activity.setContentView(Activity.java:1973)  at com.mysliderapp.MainActivity.onCreate(MainActivity.java:99)  at android.app.Activity.performCreate(Activity.java:5275)  at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1087)  at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2169)  at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2255)  at android.app.ActivityThread.access$800(ActivityThread.java:142)  at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1203)  at android.os.Handler.dispatchMessage(Handler.java:102)  at android.os.Looper.loop(Looper.java:136)  at android.app.ActivityThread.main(ActivityThread.java:5118)  at java.lang.reflect.Method.invokeNative(Native Method)  at java.lang.reflect.Method.invoke(Method.java:515)  at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:794)  at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:610)  at dalvik.system.NativeStart.main(Native Method)

Change your SlidingLayer to com.wunderlist.slidinglayer.SlidingLayer in your XML layout.

When using external compontents, Android Studio usually get problems while inflating component only by name, so you need to give full package name.

<com.wunderlist.slidinglayer.SlidingLayer
    android:id="@+id/slidingLayer1"
    android:layout_width="match_parent"
    android:layout_height="@dimen/layer_height"
    android:elevation="2dip"
    android:layout_above="@+id/linearLayout"
    android:layout_alignParentStart="true">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/primary_light">

        <WebView
            android:id="@+id/authWebView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:gravity="center"
            android:drawablePadding="15dip"
            android:paddingBottom="80dp"
            android:textSize="17sp"
            android:textColor="@color/primary_text"/>

        <Button
            android:id="@+id/buttonClose"
            style="@style/ButtonRed"
            android:onClick="buttonClicked"
            android:layout_marginBottom="60dp"
            android:layout_alignParentBottom="true"
            android:layout_centerHorizontal="true"
            android:text="@string/close_button_container"/>
    </RelativeLayout>
</com.wunderlist.slidinglayer.SlidingLayer>

Of course that won't work.Logcat says:

Caused by: java.lang.ClassNotFoundException: Didn't find class "android.view.SlidingLayer"

These things are normal or something like general skills and returns your search or skills about it.Also, you could check that library's sample too:

<com.wunderlist.slidinglayer.SlidingLayer
    xmlns:slidingLayer="http://schemas.android.com/apk/res-auto"
    android:id="@+id/slidingLayer1"
    android:layout_width="@dimen/layer_width"
    android:layout_height="@dimen/layer_height"
    slidingLayer:shadowDrawable="@drawable/sidebar_shadow"
    slidingLayer:shadowSize="@dimen/shadow_size"
    slidingLayer:offsetDistance="@dimen/offset_distance"
    slidingLayer:previewOffsetDistance="@dimen/preview_offset_distance"
    slidingLayer:stickTo="top|bottom|right|left"
    slidingLayer:changeStateOnTap="true">

    …
    …
</com.wunderlist.slidinglayer.SlidingLayer>
