Is it possible to open one app in an android device, from a website?

Will it be possible, if I have a bu开发者_JS百科tton in a website and and when clicked, it will do a trigger function and a related App will open automatically in an Android device? In iPhone it is getting possible. Thanks

From a previous Stack Overflow Question:

Launch custom android application from android browser

Namely:

Use an <intent-filter> with a <data> element. For example, to handle all links to twitter.com, you'd put this inside your <activity> in your AndroidManifest.xml:

<intent-filter>
    <data android:scheme="http" android:host="twitter.com"/>
    <action android:name="android.intent.action.VIEW" />
</intent-filter>

Then, when the user clicks on a link to twitter in the browser, they will be asked what application to use in order to complete the action: the browser or your application.

Of course, if you want to provide tight integration between your website and your app, you can define your own scheme:

<intent-filter>
    <data android:scheme="my.special.scheme" />
    <action android:name="android.intent.action.VIEW" />
</intent-filter>

Then, in your web app you can put links like:

<a href="my.special.scheme://other/parameters/here">

It is possible: you need to register a URL handler in your app.

EDIT: see How to listen for a custom URI for details.

It's also possible to launch an Android app from a web browser that's not on the device.

Take a look at Chrome to Phone for an example.
