How to open android application from a webpage?

问题:

can I call my app from HTML?

for example:I can call webpage with this code correctly from my app.

android code:

  startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(
                                    "myDomain.com")));

and after doing something in my site, I want to open my android app again.

I find this code,

<a href="market://details?id=info.androidhive.slidingmenu">

but it's just call Market to find and install the app!

You might have a look at this: https://developer.android.com/training/app-indexing/deep-linking.html

<activity
android:name="com.example.android.GizmosActivity"
android:label="@string/title_gizmos" >
<intent-filter android:label="@string/filter_title_viewgizmos">
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <!-- Accepts URIs that begin with "http://www.example.com/gizmos” -->
    <data android:scheme="http"
          android:host="www.example.com"
          android:pathPrefix="/gizmos" />
    <!-- note that the leading "/" is required for pathPrefix-->
    <!-- Accepts URIs that begin with "example://gizmos”
    <data android:scheme="example"
          android:host="gizmos" />
    -->
</intent-filter>

So your app will be started by this link:

<a href="example://gizmos">

回答2:

for iOS you can set URLSchemes that will launch the app if typed on the browser: that is for example if your app called market

market:// will launch the app

to add the URLScheme do it in the info tab :

you can handle the url options by implementing application:willFinishLaunchingWithOptions: and application:didFinishLaunchingWithOptions: methods.

You can achieve it by adding a small script in website and some changes in code. You have to make url schemes.
