  The Android M Developer Preview introduces support for App Links, which improves upon existing

  link handling by allowing app developers to associate an app with a web domain they own. When

  developers create this association, the platform can automatically determine the default app used

  to handle a particular web link and skip asking users.

<p>

  An app can indicate to the platform to verify app links against the {@code statements.json} files

  hosted on the sites defined by the host names in the <data> elements of the intent filters.

  To do this, add an {@code android:autoVerify} attribute to the appropriate intent filters in the

  manifest, as shown in the following manifest code snippet:

  An app can request that the platform automatically verify any app links defined by the host names

  in the data elements of its intent filters against the {@code statements.json} files hosted on

  the respective web domains. To request app link verification, add an {@code android:autoVerify}

  attribute to each desired intent filter in the manifest, as shown in the following manifest code

  snippet:

  When an app is installed, the platform attempts to verify the app links. If the platform cannot

  successfully verify app links, it falls back to prompting the user the next time they open a link

  that the app handles, or they will need to explicitly enable the app in the App Info settings UI.

  When the (@code android:autoVerify} attribute is present in an app manifest, the platform

  attempts to verify app links when the app is installed. If the platform cannot successfully

  verify the app links, the app is not set as the preferred app to handle the web links. The next

  time a user opens one of the links, the platform falls back to presenting the user with a

  dialog.

<p class="note">

  <strong>Note:</strong> In testing, there is a potential for a false positive if verfication

  fails, but the user has explicitly enabled the app to open supported links without asking, using

  the system Settings app. In this case, no dialog is shown and the link goes directly to your

  app, but only because of the user setting, and not because verification succeeded.
