<p>Vector Asset Studio helps you add material icons
and import Scalable Vector Graphic (SVG) files into your app project as a drawable resource.
Compared to raster images, vector drawables can reduce the size of your app and be resized without
loss of image quality. They help you to more easily support different Android devices with varying
screen sizes and resolutions because you can display one vector drawable on all of them. </p>

<h2 id="about">About Vector Asset Studio</h2>

<p>Vector Asset Studio adds a vector graphic to the project as an XML file that describes the image.
Maintaining one XML file can be easier than updating multiple raster graphics at various resolutions.</p>

<p>Android 4.4 (API level 20) and lower doesn't support vector drawables. If your minimum API level
is set at one of these API levels, Vector Asset Studio also directs Gradle to generate raster images
of the vector drawable for backward-compatibility. You can refer to vector assets as
{@link android.graphics.drawable.Drawable} in Java code or <code>@drawable</code> in XML code; when
your app runs, the corresponding vector or raster image displays automatically depending on the API
level.</p>


<h3 id="types">Supported vector graphic types</h3>

<p>The Google material design specification provides <a href="http://www.google.com/design/icons" class="external-link">material icons</a>
that you can use in your Android apps. Vector
Asset Studio helps you choose, import, and size material icons, as well as define opacity and the
Right-to-Left (RTL) mirroring setting.</p>

<p>Vector Asset Studio also helps you to import your own SVG files. SVG is an XML-based open
standard of the World Wide Web Consortium (W3C). Vector Asset Studio supports the essential
standard, but not all features. When you specify an SVG file, Vector Asset Studio gives immediate
feedback about whether the graphics code is supported or not. If the SVG code is supported, it
converts the file into an XML file containing {@link
android.graphics.drawable.VectorDrawable} code.</p>

<h3 id="when">Considerations for SVG files</h3>

<p>A vector drawable is appropriate for simple icons. The
<a href="http://www.google.com/design/icons" class="external-link">material icons</a> provide good
examples of the types
of images that work well as vector drawables in an app. In contrast, many app launch icons do have
many details, so they work better as raster images.</p>

<p>The initial loading of a vector graphic can cost more CPU cycles than the corresponding raster
image. Afterward, memory use and performance are similar between the two. We recommend that you
limit a vector image to a maximum of 200 x 200 dp; otherwise, it can take too long to draw.</p>

<p>Although vector drawables do support one or more colors, in many cases it makes sense to color
icons black (<code>android:fillColor="#FF000000"</code>). Using this approach, you can add a
<a href="{@docRoot}training/material/drawables.html#DrawableTint">tint</a> to the vector drawable
that you placed in a layout, and the icon color changes to the tint color. If the icon color
isn't black, the icon color might instead blend with the tint color.</p>

<h3 id="apilevel">Vector drawable support at different API levels</h3>

<p>Android 5.0 (API level 21) and higher provides vector drawable support. If your app has a
minimum API level that is lower, Vector Asset Studio adds the vector drawable file to your
project; also, at build time, Gradle creates Portable Network Graphic (PNG) raster images at various
resolutions. Gradle generates the PNG densities specified by the Domain Specific Language (DSL)
<a href="http://google.github.io/android-gradle-dsl/1.4/com.android.build.gradle.internal.dsl.ProductFlavor.html#com.android.build.gradle.internal.dsl.ProductFlavor:generatedDensities" class="external-link">generatedDensities</a> property
in a <code>build.gradle</code> file. To generate PNGs, the build system requires Gradle 1.4.0 or higher.</p>

<p>For Android 5.0 (API level 21) and higher, Vector Asset Studio supports all of the {@link
android.graphics.drawable.VectorDrawable} elements. For backward compatibility with Android 4.4 (API
level 20) and lower, Vector Asset Studio supports the following XML elements:</p>

<div class="wrap">
  <div class="cols">
    <div class="col-1of2">

<p><code>&lt;vector></code></p>
<ul>
  <li><code>android:width</code></li>
  <li><code>android:height</code></li>
  <li><code>android:viewportWidth</code></li>
  <li><code>android:viewportHeight</code></li>
  <li><code>android:alpha</code></li>
</ul>

</div>


<div class="col-1of2">

<p><code>&lt;path></code></p>
<ul>
  <li><code>android:pathData</code></li>
  <li><code>android:fillColor</code></li>
  <li><code>android:strokeColor</code></li>
  <li><code>android:strokeWidth</code></li>
  <li><code>android:strokeAlpha</code></li>
  <li><code>android:fillAlpha</code></li>
</ul>

</div>

</div>
</div>

<p>Only Android 5.0 (API level 21) and higher supports dynamic attributes, for example, <code>android:fillColor="?android:attr/colorControlNormal"</code>.</p>

<p>You can change the XML code that Vector Asset Studio generates, although it’s not a best practice.
Changing the values in the code should not cause any issues, as long as they’re valid and static. If
you want to add XML elements, you need to make sure that they’re supported based on your minimum API
level.</p>

<p>For Android 5.0 (API level 21) and higher, you can use the {@link
android.graphics.drawable.AnimatedVectorDrawable} class to animate the properties of {@link
android.graphics.drawable.VectorDrawable}. For more information, see
<a href="{@docRoot}training/material/animations.html#AnimVector">Animating Vector Drawables</a>.</p>

<h2 id="running">Running Vector Asset Studio</h2>

<p>Follow these steps to start Vector Asset Studio:</p>

<ol>
  <li>In Android Studio, open an Android app project.</li>
  <li>In the <em>Project</em> window, select the
  <a href="{@docRoot}sdk/installing/create-project.html#ProjectView">Android view</a>.</li>
  <li>Right-click the <strong>res</strong> folder and select <strong>New</strong> >
  <strong>Vector Asset</strong>.</li>
  <p>Some other project views and folders have this menu item as well.</p>
  <p>Vector Asset Studio appears.</p>
  <img src="{@docRoot}images/tools/vas-materialicon.png" />
  <li>If a <em>Need newer Android plugin for Gradle</em> dialog appears instead, correct
  your Gradle version as follows.</li>
    <ol type="a">
      <li>Select <strong>File</strong> > <strong>Project Structure</strong>.</li>
      <li>In the <em>Project Structure</em> dialog, select <strong>Project</strong>.</li>
      <li>In the <strong>Android Plugin Version</strong> field, change the Gradle version to
      <strong>1.4.0</strong> or higher, and click <strong>OK</strong>.</li>
      <p>Gradle syncs the project.</p>
      <li>In the <a href="{@docRoot}sdk/installing/create-project.html#ProjectView">Android view</a>
      of the <em>Project</em> window, right-click the <strong>res</strong> folder and select
      <strong>New</strong> > <strong>Vector Asset</strong>.</li>
      <p>Vector Asset Studio appears.</p>
    </ol>
  <li>Continue with <a href="#importing">Importing a Vector Graphic</a>.</li>
</ol>

<h2 id="importing">Importing a Vector Graphic</h2>

<p>Vector Asset Studio helps you to import a vector graphics file into your app project. Follow one
  of the following procedures:</p>
<ul>
  <li><a href="#materialicon">Adding a material icon</a></li>
  <li><a href="#svg">Importing an SVG file</a></li>
</ul>

<h3 id="materialicon">Adding a material icon</h3>

<p>After you <a href="#running">open Vector Asset Studio</a>, you can add a material icon as follows:</p>

<ol>
  <li>In Vector Asset Studio, select <strong>Material Icon</strong>.</li>
  <li>Click <strong>Choose</strong>.</li>
  <li>Select a material icon and click <strong>OK</strong>.</li>
  <p>The icon appears in the <strong>Vector Drawable Preview</strong>.</p>
  <li>Optionally change the resource name, size, opacity, and Right-To-Left (RTL) mirroring setting:
    <ul>
      <li><strong>Resource name</strong> - Type a new name if you don’t want to use the default name.
      Vector Asset Studio automatically creates a unique name (adds a number to the end of the name)
      if that resource name already exists in the project. The name can contain lowercase
      characters, underscores, and digits only.</li>
      <li><strong>Override default size from material design</strong> - Select this option if you
      want to adjust the size of the image. When you type a new size, the change appears in the
      preview area.</li>
      <p>The default is 24 x 24 dp, which is defined in the
      <a href="http://www.google.com/design/icons" class="external-link">material design</a>
      specification. Deselect the checkbox to return to the default.</p>
      <li><strong>Opacity</strong> - Use the slider to adjust the opacity of the image. The change
      appears in the preview area.</li>
      <li><strong>Enable auto mirroring for RTL layout</strong> - Select this option if you want a
      mirror image to display when the layout is right to left, instead of left to right. For
      example, some languages are read right to left; if you have an arrow icon, you might want to
      display a mirror image of it in this case. Note that if you’re working with an older project,
      you might also
      need to add <code>android:supportsRtl="true"</code> to your app manifest. Auto-mirroring is
      supported on Android 5.0 (API level 21) and higher only.</li>
    </ul>
  <li>Click <strong>Next</strong>.</li>
  <li>Optionally change the module and resource directory:</li>
   <ul>
      <li><strong>Target Module</strong> - Select a module in the project where you want to add the
      resource. For more information, see
      <a href="{@docRoot}sdk/installing/create-project.html#CreatingAModule">Creating an Android Module</a>.</li>
      <li><strong>Res Directory</strong> - Select the resource source set where you want to add the
      vector asset: <code>src/main/res</code>, <code>src/debug/res</code>, <code>src/release/res</code>,
      or a user-defined source set. The main source set applies to all build variants, including
      debug and release. The debug and release source sets override the main source set and apply
      to one version of a build. The debug source set is for debugging only. To define a new source
      set, select <strong>File</strong> > <strong>Project Structure</strong> > <strong>app</strong> >
      <strong>Build Types</strong>. For example, you could define a beta source set and create a
      version of an icon that includes the text "BETA” in the bottom right corner. For more information, see
      <a href="{@docRoot}tools/building/configuring-gradle.html#workBuildVariants">Working with Build Variants</a>.</li>
    </ul>
    <p>The <strong>Output Directories</strong> area displays the vector image and the directory
    where it will appear.</p>
  <li>Click <strong>Finish</strong>.</li>
  <p>Vector Asset Studio adds an XML file defining the vector drawable to the project in the
  <code>app/src/main/res/drawable/</code> folder. From the
  <a href="{@docRoot}sdk/installing/create-project.html#ProjectView">Android view</a> of the <em>Project</em>
  window, you can view the generated vector XML file in the <strong>drawable</strong> folder.</p>
  <li>Build the project.</li>
  <p>If the minimum API level is Android 4.4 (API level 20) and lower, Vector Asset Studio generates
  PNG files. From the <a href="{@docRoot}sdk/installing/create-project.html#ProjectView">Project view</a>
  of the <em>Project</em> window, you can view the generated PNG and XML files in the
  <code>app/build/generated/res/pngs/debug/</code> folder.</p>
  <p>You should not edit these generated raster files, but instead work with the vector XML file. The
  build system regenerates the raster files automatically when needed so you don’t need to maintain
  them.</p>
</ol>

<h3 id="svg">Importing a Scalable Vector Graphic (SVG)</h3>

<p>After you <a href="#running">open Vector Asset Studio</a>, you can import an SVG file as follows:</p>

<ol>
  <li>In Vector Asset Studio, select <strong>Local SVG file</strong>.</li>
  <p>The file must be on a local drive. If it’s located on the network, for example, you need to
  download it to a local drive first.</p>
  <li>Specify an <strong>Image file</strong> by clicking <strong>…</strong> .</li>
  <p>The image appears in the <strong>Vector Drawable Preview</strong>.</p>
  <p>However, if the SVG file contains unsupported features, an error appears at the bottom left of
  Vector Asset Studio, as shown in the following figure.</p>
  <img src="{@docRoot}images/tools/vas-svgerror.png" />
  <p>In this case, you can’t use Vector Asset Studio to add the graphics file. Click
    <strong>More</strong> to view the errors. For a list of supported elements, see
  <a href="#apilevel">Vector Drawable Support at Different API Levels</a>.</p>
  <li>Optionally change the resource name, size, opacity, and Right-To-Left (RTL) mirroring setting:</li>
    <ul>
      <li><strong>Resource name</strong> - Type a new name if you don’t want to use the default
      name. Vector Asset Studio automatically creates a unique name (adds a number to the end of the
      name) if that resource name already exists in the project. The name can contain lowercase
      characters, underscores, and digits only.</li>
      <li><strong>Override default size from material design</strong> - Select this option if you
      want to adjust the size of the image. After you select it, the size changes to the size of the
      image itself. Whenever you change the size, the change appears in the preview area.</li>
      <p>The default is 24 x 24 dp, which is defined in the
      <a href="http://www.google.com/design/icons" class="external-link">material design</a>
      specification. Deselect the checkbox to return to the default.</p>

  <a href="{@docRoot}sdk/installing/create-project.html#ProjectView">Android view</a> of the <em>Project</em>
  window, you can view the generated vector XML file in the <strong>drawable</strong> folder.</p>
  <li>Build the project.</li>
  <p>If the minimum API level is Android 4.4 (API level 20) and lower, Vector Asset Studio generates
  PNG files. From the <a href="{@docRoot}sdk/installing/create-project.html#ProjectView">Project view</a>
  of the <em>Project</em> window, you can view the generated PNG and XML files in the

  <p>You should not edit these generated raster files, but instead work with the vector XML file. The
  build system regenerates the raster files automatically when needed so you don’t need to maintain
  them.</p>
</ol>

<h2 id="layout">Adding a Vector Drawable to a Layout</h2>

<p>In a layout file, you can set any icon-related widget, such as {@link android.widget.ImageButton},
{@link android.widget.ImageView}, and so on, to point to a vector asset. For example, the following
layout shows a vector asset displayed on a button:</p>

<img src="{@docRoot}images/tools/vas-layout.png" />

<p>Follow these steps to display a vector asset on a widget, as shown in the figure:</p>

<ol>
  <li>Open a project and <a href="#running">import a vector asset</a>.</li>
  <li>In the <a href="{@docRoot}sdk/installing/create-project.html#ProjectView">Android view</a> of
  the <em>Project</em> window, double-click a layout XML file, such as <code>content_main.xml</code>.</li>
  <li>Click the <strong>Design</strong> tab to display the
  <a href="{@docRoot}sdk/installing/studio-layout.html">Layout Editor</a>.</li>
  <li>Drag the {@link
android.widget.ImageButton} widget from the <em>Palette</em> window onto the Layout Editor.</li>
  <li>In the <em>Properties</em> window, locate the <strong>src</strong> property of the
  <code>ImageButton</code> instance and click <strong>…</strong> .</li>
  <li>In the <em>Resources</em> dialog, select the <strong>Project</strong> tab, navigate to the
    <strong>Drawable</strong> folder, and select a vector asset. Click <strong>OK</strong>.</li>
  <p>The vector asset appears on the <code>ImageButton</code> in the layout.</p>
  <li>To change the color of the image to the accent color defined in the theme, locate the
  <strong>tint</strong> property in the <em>Properties</em> window and click <strong>…</strong> .</li>
  <li>In the <em>Resources</em> dialog, select the <strong>Project</strong> tab, navigate to the
  <strong>Color</strong> folder, and select <strong>colorAccent</strong>. Click <strong>OK</strong>.</li>
  <p>The color of the image changes to the accent color in the layout.</p>
</ol>

<p>The <code>ImageButton</code> code should be similar to the following:</p>

<pre>
&lt;ImageButton
  android:id="@+id/imageButton"
  android:src="@drawable/ic_build_24dp"
  android:tint="@color/colorAccent"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_below="@+id/textView2"
  android:layout_marginTop="168dp" />
</pre>

<h2 id="referring">Referring to a Vector Drawable in Code</h2>

<p>You can normally refer to a vector drawable resource in a generic way in your code, and when
your app runs, the corresponding vector or raster image displays automatically depending on the API
level:</p>

<ul>
  <li>In most cases, you can refer to vector assets as <code>@drawable</code> in XML code or
    {@link android.graphics.drawable.Drawable} in Java code. </li>
  <p>For example, the following layout XML code applies the image to a view:</p>
<pre>
&lt;ImageView
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:src="@drawable/myimage" />
</pre>
  <p>The following Java code retrieves the image as a {@link android.graphics.drawable.Drawable}:</p>
<pre>
Resources res = {@link android.content.Context#getResources()};
Drawable drawable = res.{@link android.content.res.Resources#getDrawable(int) getDrawable}(R.drawable.myimage);
</pre>
  <li>Occasionally, you might need to typecast the drawable resource to its exact class, such as
  when you need to use specific features of the {@link android.graphics.drawable.VectorDrawable}
  class. To do so, you could use Java code such as the following:</li>
<pre>
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
   VectorDrawable vectorDrawable =  (VectorDrawable) drawable;
} else {
   BitmapDrawable bitmapDrawable = (BitmapDrawable) drawable;
}
</pre>
</ul>


<h2 id="code">Modifying XML Code Generated by Vector Asset Studio</h2>

<p>You can modify the vector asset XML code, but not the PNGs and corresponding XML code generated
at build time. However, we don't recommended it. Vector Asset Studio makes sure that the vector
drawable and the PNGs match, and that the manifest contains the proper code. If you add code that's
<a href="#apilevel">not supported</a> on Android 4.4 (API level 20) and lower, your vector and PNG
images might differ. You also need to make sure that the manifest contains the code to support your
changes.</p>

<p>Follow these steps to modify the vector XML file:</p>

<ol>
  <li>In the <em>Project</em> window, double-click the generated vector XML file in the
  <strong>drawable</strong> folder.</li>
  <p>The XML file appears in the editor and <em>Preview</em> windows.</p>

  <img src="{@docRoot}images/tools/vas-codepreview.png" />

  <li>Edit the XML code based on what’s supported by the minimum API level:</li>
    <ul>
      <li>Android 5.0 (API level 21) and higher - Vector Asset Studio supports all of the
      {@link android.graphics.drawable.Drawable} and
      {@link android.graphics.drawable.VectorDrawable} elements. You can add XML elements and
      change values.</li>
      <li>Android 4.4 (API level 20) and lower - Vector Asset Studio supports all of the
      {@link android.graphics.drawable.Drawable} elements and a subset of the
      {@link android.graphics.drawable.VectorDrawable} elements. See
      <a href="#apilevel">Support at Different API Levels</a> for a list. You can change values in
      the generated code and add XML elements that are supported. Dynamic attributes aren't
      supported.</li>
   </ul>
  <p>For example, if you didn’t select the RTL option in Vector Asset Studio but realize you now
  need it, you can add the <a href="{@docRoot}reference/android/R.attr.html#autoMirrored">autoMirrored</a>
  attribute later. To view the RTL version, select <strong>Preview Right-to-Left Layout</strong> in
  the <img src="{@docRoot}images/tools/vas-rtlmenu.png" style="vertical-align:sub;margin:0;height:17px" alt="" />
  menu of the <em>Preview</em> window. (Select <strong>None</strong> to remove the RTL preview.)</p>
<img src="{@docRoot}images/tools/vas-rtl.png" />
  <p class="note"><strong>Note:</strong> If you’re working with an older project, you might need to
  add <code>android:supportsRtl="true"</code> to your app manifest. Also, because
  <code>autoMirrored</code> is a dynamic attribute, it's supported on Android 5.0 (API level 21) and
  higher only.</p>
  <li>Build the project and check that the vector and raster images look the same.</li>
  <p>Remember that the generated PNGs could display differently in the <em>Preview</em> window than
  in the app due to different rendering engines and any changes made to the vector drawable before a
  build. If you add code to the vector XML file created by Vector Asset Studio, any features
  unsupported in Android 4.4 (API level 20) and lower don't appear in the generated PNG files. As a
  result, when you add code, you should always check that the generated PNGs match the vector
  drawable. To do so, you could double-click the PNG in the
  <a href="{@docRoot}sdk/installing/create-project.html#ProjectView">Project view</a> of the <em>Project</em>
  window; the left margin of the code editor also displays the PNG image when your code refers to
  the drawable.</p>
  <img src="{@docRoot}images/tools/vas-imageincode.png" />
</ol>


<h2 id="delete">Deleting a Vector Asset from a Project</h2>

<p>Follow these steps to remove a vector asset from a project:</p>

<ol>
  <li>In the <em>Project</em> window, delete the generated vector XML file by selecting the file and
  pressing the <strong>Delete</strong> key (or select <strong>Edit</strong> > <strong>Delete</strong>).</li>
  <p>The <em>Safe Delete</em> dialog appears.</p>
  <li>Optionally select options to find where the file is used in the project, and click
  <strong>OK</strong>.</li>
  <p>Android Studio deletes the file from the project and the drive. However, if you chose to search
  for places in the project where the file is used and some usages are found, you can view them and
  decide whether to delete the file.</p>
  <li>Select <strong>Build</strong> > <strong>Clean Project</strong>.</li>
  <p>Any auto-generated PNG and XML files corresponding to the deleted vector
  asset are removed from the project and the drive.</p>
</ol>

<h2 id="apk">Delivering an App Containing Vector Drawables</h2>

<p>When your minimum API level includes Android 4.4 (API level 20) or lower, you have corresponding
  vector and raster images in your project. In this case, you have two options for delivering your
  APK files:</p>

<ul>
  <li>Create one APK that includes both the vector images and the corresponding raster
    representations. This is the easiest solution.</li>
  <li>Create separate APKs for different API levels. When you don’t include the corresponding
    raster images in the APK for Android 5.0 (API level 21) and higher, the APK can be much smaller in
    size. For more information, see <a href="{@docRoot}google/play/publishing/multiple-apks.html">Multiple APK Support</a>.</li>
