     27 <p>Before you publish an app on Google Play, it's important to make sure that
     28 the app meets the basic expectations of tablet users through compelling features
     29 and an intuitive, well-designed UI. </p>
     30 
     31 <p>Tablets are a growing part of the Android installed base that offers new
     32 opportunities for <a
     33 href="{@docRoot}distribute/googleplay/spotlight/tablets.html">user engagement
     34 and monetization</a>. If your app is targeting tablet users, this document helps
     35 you focus on key aspects of quality, feature set, and UI that can have a
     36 significant impact on the app's success. Each focus area is given as checklist
     37 item, with each one comprising several smaller tasks or best practices.</p>
     38 
     39 <p>Although the checklist tasks below are numbered for convenience, 
     40 you can handle them in any order and address them to the extent that you feel
     41 is right for your app. In the interest of delivering the best possible product
     42 to your customers, follow the checklist recommendations
     43 to the greatest extent possible. </p>
     44 
     45 <p>As you move through the checklist, you'll find links to support resources
     46 that can help you address the topics raised in each task.</p>

     49 <h2 id="core-app-quality">1. Test for Core App Quality</h2>
     50 
     51 <p>The first step in delivering a great tablet app experience is making sure
     52 that it meets the <em>core app
     53 quality criteria</em> for all of the devices and form factors that the app is
     54 targeting. For complete information, see the <a
     55 href="{@docRoot}distribute/googleplay/quality/core.html">Core App Quality Checklist</a>. 
     56 </p>
     57 
     58 <p>To assess the quality of your app on tablets &mdash; both for core app quality
     59 and tablet app quality &mdash; you need to set up a suitable
     60 hardware or emulator environment for testing. For more information, 
     61 see <a href="#test-environment">Setting Up a Test Environment</a>.</p>

     76 <h2 id="optimize-layouts">2. Optimize your layouts for larger screens</h2>
     77 
     78 <p>Android makes it easy to develop an app that runs well on a wide range of
     79 device screen sizes and form factors. This broad compatibility works in your
     80 favor, since it helps you design a single app that you can distribute widely to
     81 all of your targeted devices. However, to give your users the best possible
     82 experience on each screen configuration &mdash; in particular on tablets
     83 &mdash; you need to optimize your layouts and other UI components for each
     84 targeted screen configuration. On tablets, optimizing your UI lets you take
     85 full advantage of the additional screen available, such as to offer new features,
     86 present new content, or enhance the experience in other ways to deepen user
     87 engagement.</p>
     88 
     89 <p>If you developed your app for handsets and now want to distribute it to
     90 tablets, you can start by making minor adjustments to your layouts, fonts, and
     91 spacing. In some cases &mdash; such as for 7-inch tablets or for a game with
     92 large canvas &mdash; these adjustments may be all
     93 you need to make your app look great. In other cases, such as for larger
     94 tablets, you can redesign parts of your UI to replace "stretched UI" with an
     95 efficient multipane UI, easier navigation, and additional content. </p>
     96 
     97 <p>Here are some suggestions:</p>
     98 
     99 <div style="width:390px;float:right;margin:1.5em;margin-top:0em;">
    100 <img src="{@docRoot}images/training/app-navigation-multiple-sizes-multipane-bad.png" style="width:390px;padding:4px;margin-bottom:0em;">
    101 <p class="image-caption" style="padding:0em .5em .5em 2em"><span
    102 style="font-weight:500;">Get rid of "stretched" UI</span>: On tablets, single-pane layouts lead to awkward whitespace and excessive line lengths. Use padding to reduce the width of UI elements and consider using multi-pane layouts.</p>
    103 </div>
    104 
    105 <ul>
    106 <li>Provide custom layouts as needed for <code>large</code> and
    107 <code>xlarge</code> screens. You can also provide layouts that are loaded based
    108 on the screen's <a href="{@docRoot}guide/practices/screens_support.html#NewQualifiers">shortest
    109 dimension</a> or the <a href="{@docRoot}guide/practices/screens_support.html#NewQualifiers">minimum
    110 available width and height</a>. </li>
    111 <li>At a minimum, customize dimensions such as font sizes, margins, spacing for
    112 larger screens, to improve use of space and content legibility. </li>
    113 <li>Adjust positioning of UI controls so that they are easily accessible to
    114 users when holding a tablet, such as toward the sides when in
    115 landscape orientation.</li>
    116 <li>Padding of UI elements should normally be larger on tablets than on handsets. A
    117 <a href="{@docRoot}design/style/metrics-grids.html#48dp-rhythm">48dp rhythm</a> (and a 16dp
    118 grid) is recommended.</li>
    119 <li>Adequately pad text content so that it is not aligned directly along screen edges.
    120 Use a minimum <code>16dp</code> padding around content near screen edges.</li>
    121 </ul>
    122 
    123 <p>In particular, make sure that your layouts do not appear "stretched"
    124 across the screen:</p>
    125 
    126 <ul>
    127 <li>Lines of text should not be excessively long &mdash; optimize for a maximum
    128 100 characters per line, with best results between 50 and 75.</li>
    129 <li>ListViews and menus should not use the full screen width.</li>
    130 <li>Use padding to manage the widths of onscreen elements or switch to a
    131 multi-pane UI for tablets (see next section).</li>

    157 </div>
    158 
    159 <p>Tablet screens provide significantly more screen real estate to your app,
    160 especially when in landscape orientation. In particular, 10-inch tablets offer a
    161 greatly expanded  area, but even 7-inch tablets give you more space for
    162 displaying content and engaging users. </p>
    163 
    164 <p>As you consider the UI of your app when running on tablets, make sure that it
    165 is taking full advantage of extra screen area available on tablets. Here are
    166 some suggestions:</p>
    167 
    168 <ul>
    169 <li>Look for opportunities to include additional content or use an alternative
    170 treatment of existing content.</li>
    171 <li>Use <a href="{@docRoot}design/patterns/multi-pane-layouts.html">multi-pane
    172 layouts</a> on tablet screens to combine single views into a compound view. This
    173 lets you use the additional screen area more efficiently and makes it easier for
    174 users to navigate your app. </li>
    175 <li>Plan how you want the panels of your compound views to reorganize when
    176 screen orientation changes.</li>

    187 </div>
    188 </div>
    189 
    190 <li>While a single screen is implemented as an {@link android.app.Activity}
    191 subclass, consider implementing individual content panels as {@link
    192 android.app.Fragment} subclasses. This lets you maximize code reuse across
    193 different form factors and across screens that share content.</li>
    194 <li>Decide on which screen sizes you'll use a multi-pane UI, then provide the
    195 different layouts in the appropriate screen size buckets (such as
    196 <code>large</code>/<code>xlarge</code>) or minimum screen widths (such as
    197 <code>sw600dp</code>/<code>sw720</code>).</li>

    285 <h2 id="adjust-font-sizes">5. Adjust font sizes and touch targets for tablet screens</h2>
    286 
    287 <p>To make sure your app is easy to use on tablets, take some time to adjust the
    288 font sizes and touch targets in your tablet UI, for all of the screen
    289 configurations you are targeting. You can adjust font sizes through <a
    290 href="{@docRoot}guide/topics/ui/themes.html">styleable attributes</a> or <a
    291 href="{@docRoot}guide/topics/resources/more-resources.html#Dimension">dimension
    292 resources</a>, and you can adjust touch targets through layouts and bitmap
    293 drawables, as discussed above. </p>
    294 
    295 <p>Here are some considerations:</p>
    296 <ul>
    297 <li>Text should not be excessively large or small on tablet screen sizes and
    298 densities. Make sure that labels are sized appropriately for the UI elements they
    299 correspond to, and ensure that there are no improper line breaks in labels,
    300 titles, and other elements.</li>
    301 <li>The recommended touch-target size for onscreen elements is 48dp (32dp
    302 minimum) &mdash; some adjustments may be needed in your tablet UI. Read <a
    303 href="http://developer.android.com/design/style/metrics-grids.html">Metrics and
    304 Grids
    305 </a> to learn about implementation strategies to help most of your users. To
    306 meet the accessibility needs of certain users, it may be appropriate to use
    307 larger touch targets. </li>
    308 <li>When possible, for smaller icons, expand the touchable area to more than
    309 48dp using {@link android.view.TouchDelegate} or just centering the icon within
    310 the transparent button.</li>

    332 
    333 <ul>
    334 <li>Make sure that the widget's default height and width are set appropriately

    336 </li>
    337 <li>The widget should be resizable to 420dp or more, to span 5 or more home
    338 screen rows (if this is a vertical or square widget) or columns (if this is a
    339 horizontal or square widget). </li>
    340 <li>Make sure that 9-patch images render correctly.</li>
    341 <li>Use default system margins.</li>
    342 <li>Set the app's <code>targetSdkVersion</code> to 14 or higher, if
    343 possible.</li>

    359 <h2 id="offer-full-feature-set">7. Offer the app's full feature set to tablet users</h2>
    360 
    361 <p>Let your tablet users experience the best features of your app. Here are
    362 some recommendations:</p>
    363 
    364 <ul>
    365 <li>Design your app to offer at least the same set of features on tablets as it does on
    366 handsets. </li>
    367 <li>In exceptional cases, your app might omit or replace certain features on
    368 tablets if they are not supported by the hardware or use-case of most tablets.
    369 For example:
    370 <ul>
    371 <li>If the handset uses telephony features but telephony is not available on the
    372 current tablet, you can omit or replace the related functionality.</li>
    373 <li>Many tablets have a GPS sensor, but most users would not normally carry
    374 their tablets while running. If your phone app provides functionality to let the
    375 user record a GPS track of their runs while carrying their phones, the app would not need to
    376 provide that functionality on tablets because the use-case is not
    377 compelling.</li>
    378 </ul>
    379 </li>
    380 <li>If you will omit a feature or capability from your tablet UI, make sure

    382 to a replacement feature (also see the section below on hardware features).</li>

    385 
    386 <h2 id="hardware-requirements">8. Dont require hardware features that might not be available on tablets</h2>
    387 
    388 <p>Handsets and tablets typically offer slightly different hardware support for
    389 sensors, camera, telephony, and other features. For example, many tablets are
    390 available in a "Wi-Fi" configuration that does not include telephony support.</p>
    391 
    392 <p>To ensure that you can deliver a single APK broadly across the
    393 your full customer base, make sure that your app does not have built-in
    394 requirements for hardware features that aren't commonly available on tablets.
    395 </p>
    396 
    397 <ul>
    398 <li>Your app's manifest should not include <a
    399 href="{@docRoot}guide/topics/manifest/uses-feature-element.html"><code>&lt;uses-feature&gt;</code></a>
    400 elements for hardware features or capabilities that might not be
    401 available on tablets, except when they are declared with the
    402 <code>android:required=false</code> attribute. For example, your app should
    403 not <em>require</em> features such as:
    404 <ul>
    405 <li><code>android.hardware.telephony</code></li>
    406 <li><code>android.hardware.camera</code> (refers to back camera), or</li>
    407 <li><code>android.hardware.camera.front</code></li>
    408 </ul>
    409 </li>
    410 <li>Similarly, your app manifest should not include any <a
    411 href="{@docRoot}guide/topics/manifest/permission-element.html"><code>&lt;permission&gt;</code></a> elements that <a
    412 href="{@docRoot}guide/topics/manifest/uses-feature-element.html#permissions">imply
    413 feature requirements</a> that might not be appropriate for tablets, except when
    414 accompanied by a corresponding <code>&lt;uses-feature&gt;</code> element
    415 declared with the <code>android:required=false</code> attribute.</li>
    416 </ul>
    417 
    418 <p>In all cases, the app must function normally when the hardware features it
    419 uses are not available and should offer graceful degradation and alternative
    420 functionality where appropriate. For example, if GPS is not supported on the device,
    421 your app could let the user set their location manually. The app should do
    422 run-time checking for the hardware capability that it needs and handle as needed.</p>

    474     <li>Easier for users to find your app from search, browsing, or promotions</li>
    475     <li>Easier for users to restore your app automatically if they get a new device.</li>
    476     <li>Your ratings and download stats are consolidated across all devices.</li>
    477     <li>Publishing a tablet app in a second listing can dilute ratings for your brand.</li>
    478   </ul>
    479 </li>
    480 <li>If necessary, you can alternatively choose to deliver your app using <a 
    481 href="{@docRoot}guide/google/play/publishing/multiple-apks.html">Multiple APK Support</a>, 
    482 although in most cases using a single APK to reach all devices is strongly recommended.</li>
    483 
    484 <li>Highlight your apps tablet capabilities in the product details page:
    485   <ul style="margin-top:.25em;">
    486     <li>Add <strong>at least one screenshot taken while the app is running on a
    487     tablet</strong>. It's recommended that you add one screenshot of landscape orientation
    488     and one of portrait orientation, if possible. These screenshots make it clear to users
    489     that your app is designed for tablets and highlight all the effort you've put into designing
    490     a great tablet app experience.</li>
    491     <li>Mention tablet support in the app description.</li>
    492     <li>Include information about tablet support in the app's release notes and update
    493     information.</li>
    494     <li>In your app's promo video, add shots of your app running on a tablet.</li>
    495   </ul>
    496 </li>
    497 <li>Make sure you are distributing to tablet devices. Check the app's Supported Devices

    517 
    518 <p>To assess the quality of your app on tablets &mdash; both for core app quality
    519 and tablet app quality &mdash; you need to set up a suitable
    520 hardware or emulator environment for testing. </p>
    521 
    522 <p>The ideal test environment would
    523 include a small number of actual hardware devices that represent key form
    524 factors and hardware/software combinations currently available to consumers.
    525 It's not necessary to test on <em>every</em> device that's on the market &mdash;
    526 rather, you should focus on a small number of representative devices, even using
    527 one or two devices per form factor.  The table below provides an overview of
    528 devices you could use for testing.</p>
    529 
    530 <p>If you are not able to obtain actual hardware devices for testing, you should
    531 <a href="{@docRoot}tools/devices/index.html">set up emulated devices (AVDs)</a>
    532 to represent the most common form factors and
    533 hardware/software combinations. See the table below for suggestions on the emulator
    534 configurations to use. </p>
    535 
    536 <p>To go beyond basic testing, you can add more devices, more form factors, or
    537 new hardware/software combinations to your test environment. For example, you
    538 could include mid-size tablets, tablets with more or fewer hardware/software
    539 features, and so on. You can also increase the number or complexity of tests
    540 and quality criteria. </p>
