Android Studio: Rendering Problems with CoordinatorLayout

Question

When I set a CoordinatorLayout as my root element I get the following error when Android Studio is rendering a preview.

java.lang.NoClassDefFoundError: Could not initialize class android.support.design.widget.CoordinatorLayout     at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)     at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39)     at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27)     at java.lang.reflect.Constructor.newInstance(Constructor.java:513)     at org.jetbrains.android.uipreview.ViewLoader.createNewInstance(ViewLoader.java:413)     at org.jetbrains.android.uipreview.ViewLoader.loadView(ViewLoader.java:105)     at com.android.tools.idea.rendering.LayoutlibCallback.loadView(LayoutlibCallback.java:177)     at android.view.BridgeInflater.loadCustomView(BridgeInflater.java:214)     at android.view.BridgeInflater.createViewFromTag(BridgeInflater.java:142)     at android.view.LayoutInflater.inflate(LayoutInflater.java:482)     at android.view.LayoutInflater.inflate(LayoutInflater.java:385)     at com.android.layoutlib.bridge.impl.RenderSessionImpl.inflate(RenderSessionImpl.java:413)     at com.android.layoutlib.bridge.Bridge.createSession(Bridge.java:321)     at com.android.ide.common.rendering.LayoutLibrary.createSession(LayoutLibrary.java:350)     at com.android.tools.idea.rendering.RenderTask$2.compute(RenderTask.java:497)     at com.android.tools.idea.rendering.RenderTask$2.compute(RenderTask.java:485)     at com.intellij.openapi.application.impl.ApplicationImpl.runReadAction(ApplicationImpl.java:894)     at com.android.tools.idea.rendering.RenderTask.createRenderSession(RenderTask.java:485)     at com.android.tools.idea.rendering.RenderTask.render(RenderTask.java:590)     at org.jetbrains.android.uipreview.AndroidLayoutPreviewToolWindowManager.doRender(AndroidLayoutPreviewToolWindowManager.java:644)     at org.jetbrains.android.uipreview.AndroidLayoutPreviewToolWindowManager.access$1700(AndroidLayoutPreviewToolWindowManager.java:79)     at org.jetbrains.android.uipreview.AndroidLayoutPreviewToolWindowManager$7$1.run(AndroidLayoutPreviewToolWindowManager.java:586)     at com.intellij.openapi.progress.impl.CoreProgressManager$2.run(CoreProgressManager.java:152)     at com.intellij.openapi.progress.impl.CoreProgressManager.registerIndicatorAndRun(CoreProgressManager.java:452)     at com.intellij.openapi.progress.impl.CoreProgressManager.executeProcessUnderProgress(CoreProgressManager.java:402)     at com.intellij.openapi.progress.impl.ProgressManagerImpl.executeProcessUnderProgress(ProgressManagerImpl.java:54)     at com.intellij.openapi.progress.impl.CoreProgressManager.runProcess(CoreProgressManager.java:137)     at org.jetbrains.android.uipreview.AndroidLayoutPreviewToolWindowManager$7.run(AndroidLayoutPreviewToolWindowManager.java:581)     at com.intellij.util.ui.update.MergingUpdateQueue.execute(MergingUpdateQueue.java:320)     at com.intellij.util.ui.update.MergingUpdateQueue.execute(MergingUpdateQueue.java:310)     at com.intellij.util.ui.update.MergingUpdateQueue$2.run(MergingUpdateQueue.java:254)     at com.intellij.util.ui.update.MergingUpdateQueue.flush(MergingUpdateQueue.java:269)     at com.intellij.util.ui.update.MergingUpdateQueue.flush(MergingUpdateQueue.java:227)     at com.intellij.util.ui.update.MergingUpdateQueue.run(MergingUpdateQueue.java:217)     at com.intellij.util.concurrency.QueueProcessor.runSafely(QueueProcessor.java:238)     at com.intellij.util.Alarm$Request$1.run(Alarm.java:351)     at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:439)     at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303)     at java.util.concurrent.FutureTask.run(FutureTask.java:138)     at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:895)     at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:918)     at java.lang.Thread.run(Thread.java:695) 

My layout file looks like this

<?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout      xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     android:id="@+id/main_content"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:fitsSystemWindows="true">      <android.support.design.widget.AppBarLayout         android:id="@+id/appbar_layout"         android:layout_width="match_parent"         android:layout_height="@dimen/detail_backdrop_height"         android:fitsSystemWindows="true"         android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">          <android.support.design.widget.CollapsingToolbarLayout             android:id="@+id/collapsing_toolbar"             android:layout_width="match_parent"             android:layout_height="match_parent"             android:fitsSystemWindows="true"             app:contentScrim="?attr/colorPrimary"             app:expandedTitleMarginEnd="64dp"             app:expandedTitleMarginStart="48dp"             app:layout_scrollFlags="scroll|exitUntilCollapsed">              <ImageView                 android:id="@+id/img"                 android:layout_width="match_parent"                 android:layout_height="match_parent"                 android:fitsSystemWindows="true"                 android:adjustViewBounds="true"                 android:scaleType="centerCrop"                 app:layout_collapseMode="parallax" />              <android.support.v7.widget.Toolbar                 android:id="@+id/toolbar"                 android:layout_width="match_parent"                 android:layout_height="?attr/actionBarSize"                 app:layout_collapseMode="pin"                 app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />          </android.support.design.widget.CollapsingToolbarLayout>      </android.support.design.widget.AppBarLayout>      <android.support.v7.widget.RecyclerView         android:id="@+id/detail_recyclerview"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_below="@id/appbar_layout"         android:layout_marginTop="-25dp"         android:background="@color/background_light"         android:paddingTop="36dp"         android:scrollbars="vertical"         app:layout_behavior="@string/appbar_scrolling_view_behavior" />      <android.support.design.widget.FloatingActionButton         android:id="@+id/fab"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignParentEnd="true"         android:layout_below="@id/appbar_layout"         android:layout_gravity="bottom|end"         android:layout_marginEnd="16dp"         android:layout_marginTop="-32dp"         android:src="@android:drawable/ic_menu_call"         app:layout_scrollFlags="scroll|exitUntilCollapsed" /> </android.support.design.widget.CoordinatorLayout> 

Here is my build.gradle

apply plugin: 'com.android.application'  android {     compileSdkVersion 22     buildToolsVersion "21.1.2"      defaultConfig {         applicationId "com.godine"         minSdkVersion 21         targetSdkVersion 22         versionCode 1         versionName "1.0"     }     buildTypes {         release {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }     }     lintOptions {         abortOnError false     } }    dependencies {     compile fileTree(dir: 'libs', include: ['*.jar'])     compile 'com.android.support:cardview-v7:22.2.0'     compile 'com.android.support:recyclerview-v7:22.2.0'     compile 'com.android.support:design:22.2.0'     compile 'com.android.support:appcompat-v7:22.2.0'      ... } 

Does anyone have an idea what might be wrong here?

Edit As @deniz already mentioned in an answer the preview works with the newest update of the Android Studio

Answer 1

This is a known issue in the Android Open Source Project Issue Tracker:

https://code.google.com/p/android/issues/detail?id=175595

The unfortunate workaround described by the Android project member is:

Workarounds: Try rendering with M preview using AS v1.3 preview OR use FrameLayout for designing and change to android.support.design.widget.CoordinatorLayout while debugging.

Answer 2

Update android studio to latest version (beta) 1.3 beta version.Menu -> 'Check for updates'

If you are not able to find the beta update change android studio settings(Updates), then update that patch and render with M preview

Try Renderring your preview using Android M preview.
