How do I pass parameters to android Intent in new scheme on chrome?

Question

I have a web app calling a native app on android via an iframe intent which does not work in chrome 25 according to the following....

https://developers.google.com/chrome/mobile/docs/intents

The intent was structured like the following....

app://Requesttype=Testing&Type=123&tn=0000000000

In the new intent:// scheme how would I go about passing the parameters listed after app:// to the native application? I haven't been able to find an example.

Answer 1

With the new scheme, you can pass arguments as extras to the App, but you must encode the URI as follows:

<a href="intent://whatever/#Intent;scheme=myapp;package=com.what.ever.myapp;S.myextra=mystring;end">Do Whatever</a> 

This will pass an extra String called "myextra" with the value "mystring". Having a look at the Android Code we can see how the extra parameters need to be coded. The "S" at the beginning of the "myextra" parameter defines it as a String. Other types can be:

String => 'S' Boolean =>'B' Byte => 'b' Character => 'c' Double => 'd' Float => 'f' Integer => 'i' Long => 'l' Short => 's' 

For example, if we want to pass two extra parameters, an Integer and a String, we can do this:

<a href="intent://whatever/#Intent;scheme=myapp;package=com.what.ever.myapp;S.name=Perico%20de%20los%20Palotes;i.age=35;end">Do Whatever</a> 

Note that you'll need to url-encode all the parameters.

In your Android app, you'll need to accept those extras. In the "onCreate" event of your Activity:

Bundle parametros = getIntent().getExtras(); if (extras != null){     String name = extras.getString("name");     Integer age = extras.getInt("age");      if (name!=null && age!=null)     {        //do whatever you have to        //...     } }else{      //no extras, get over it!! } 

And, of course, add the filter android.intent.category.BROWSABLE in your manifest as shown in this link.

For the scheme URL:

appname://RequestType/?Type=123&tn=0000000000 

You would want to map to an intent URL of:

intent://RequestType/?Type=123&tn=0000000000#Intent;scheme=appname;package=com.example.appname;end
