As Google Developer, we can run Android Application from Chrome(Google Developer).
iOS has just same feature using Safari.

Prepare Android Application

You need to change AndroidManifest.xml
The following is example of MainActivity.

<activity android:label="@string/app_name" android:name="com.atmarkplant.webapp.MainActivity" android:screenOrientation="portrait" android:theme="@android:style/Theme.Holo.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
            <intent-filter>
        	<action android:name="android.intent.action.VIEW"/>
        	<category android:name="android.intent.category.DEFAULT"/>
        	<category android:name="android.intent.category.BROWSABLE"/>
        	<data android:scheme="key" android:host="application" android:path="/"/>
      	    </intent-filter>
 </activity>

Prepare URL

Create link in any server you have.
The link is 

<a href="intent://application/#Intent;scheme=key;package=com.atmarkplant.webapp;end"> Start Web App </a>

Style is 

intent:
   HOST/URI-path // Optional host 
   #Intent; 
      package=[string]; 
      action=[string]; 
      category=[string]; 
      component=[string]; 
      scheme=[string]; 
   end;

In this example, application is HOT/URI, schema is key, package is com.atmarkplant.webapp
These settings are in

How to run?

Open your Chrome and access your server and touch link.
You can see opening application.

How to pass parameters

You change link like that

<a href="intent://application/#Intent;scheme=key;package=com.atmarkplant.webapp;S.key1=value1;S.key2=value2;end"> Start Web App </a>

About parameter, stackoverflow explains alot

How to get parameters

I think onCreate, onStart, onResume are fine.

Intent intent = getIntent();
String value1 = intent.getStringExtra("key1");
String value2 = intent.getStringExtra("key2");

The key is to get Intent. If you invoke this application normally, value1, value2 are null.
