There is only one simple connection in the HTML page with the following code:
<html> <head> <meta http-equiv="Content-type" Content="text/html; Charset=utf-8 "> <title>Insert Title here</title> </head> <body> <a href="ky://www.keyisoftware.com/vpn?name=daqin&pwd=12345678">Open app</a><br/> </body></html>Androidmanifest.xml need to filter the intent, configured as follows:
<?xml version= "1.0" encoding= "Utf-8"?><manifest xmlns:android="Http://schemas.android.com/apk/res/android" package ="Test.keyisoftware.tstartappbyweb"android:versioncode="1"android: Versionname="1.0" > <uses-sdkandroid:minsdkversion="android:targetsdkversion" ="/>" <applicationandroid:allowbackup="true"android:icon="@drawable/ Ic_launcher "android:label=" @string/app_name "android:theme=" @style/apptheme " > <activityandroid:name=". Mainactivity "android:label=" @string/app_name " > <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" /> <dataandroid:host= "www.keyisoftware.com"android:scheme=" KY " /> </intent-filter> </activity> </Application></manifest>3, the Web page to pass data to the appNote: The name in the Android:scheme must be all lowercase.
Just open the app is the most basic function, the actual application, usually in the open at the same time pass the corresponding parameters, such as the realization of single sign-on, QR code scanning and so on.
As in the above connection, the corresponding user name and password are passed:ky://www.keyisoftware.com/vpn?name=daqin&pwd=12345678

PackageTest.keyisoftware.tstartappbyweb;Importandroid.app.Activity;ImportAndroid.content.Intent;ImportAndroid.net.Uri;ImportAndroid.os.Bundle;ImportAndroid.util.Log;ImportAndroid.widget.Toast; Public class mainactivity extends Activity { @Override protected void onCreate(Bundle savedinstancestate) {Super. OnCreate (Savedinstancestate); Setcontentview (R.layout.activity_main);//Get the data that the page passes overIntent Intent = Getintent (); String scheme = Intent.getscheme (); Uri uri = Intent.getdata (); StringBuffer buffer =NewStringBuffer ();if(URI! =NULL) {//Get domain name, not including PortBuffer.append ("host="+ Uri.gethost ());//Get all the strings passed inBuffer.append ("datastring="+ intent.getdatastring ());//Get pathBuffer.append ("Path="+ Uri.getpath ());//Get all the parametersBuffer.append ("query="+ uri.getquery ());//Gets the value of the parameterBuffer.append ("Name="+ Uri.getqueryparameter ("Name") +"pwd="+ Uri.getqueryparameter ("PWD")); } String str ="Scheme="+ scheme + buffer.tostring (); LOG.I ("Tstartappbyweb", str); Toast.maketext ( This, str, toast.length_short). Show (); }}Note: To open the app's browser using the above method, the kernel must be webkit.
