Open android application from a web page

Question

I know that for opening android application from a link inside a web page we have to write the following in the AndroidManifest.xml:

        <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="my_scheme" android:host="my_host" />
        </intent-filter>

The problem is that I wrote it in the following way:

        <intent-filter>
            <action android:name="my_action"/>
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data android:scheme="my_scheme" android:host="my_host" />
        </intent-filter>

I didn't add android.intent.action.VIEW and instead I added my own action that i made. I can't change it because the version is already released.

The question is,

if there's a way to make the application run from JavaScript or simple html page, maybe by defining the specific action in the page?

Thanks,

Paz.

SOLVED:

Thanks to David I found a solution:

<a href="intent://my_host#Intent;scheme=my_scheme;action=my_action;end">Link to my stuff</a> 

Solution 1

Try this:

Make your links look like this:

<a href="intent:#Intent;action=my_action;end">Link to my stuff</a>

Also have a look at Launch custom android application from android browser

Solution 2

AndroidMainfest declare:

<activity android:name="...">
<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:host="hostName"
     android:path="path"
     android:scheme="schemeName" />
   </intent-filter>
</activity>

you can let to invoke

<a href = "schemeName://hostName/path">

or add param similar url in brower

<a href = "schemeName://hostName/path?id=1&name=mark">

Solution 3

One way as 林平君 saied,and another way by invoking js method ,code as follow:

function openAActivity(){
     window.location = "schemeName://hostName/path"

}

this method will send an Android intent to start specified activity.

Why can't you just release an update to the market to fix it?

[Paz]

It will surely solve the problem but i just can't release a new version due to company limitations.

Thanks David, what do you mean by intent:#Intent? shouldn't it be my_scheme://my_host or should i write it as it is (intent:#Intent)?

[David Wasser]

I've not tried this myself, but it looks like you can launch an Intent from a web browser by using this link format. I don't think your myscheme://my_host URL will work in this case because the browser will just create an Intent with action=android.intent.action.VIEW and this won't match your Intent filter. You'll need to play with it some. Let me know if you figure it out.

Hi David, since i'm using host and scheme, this is the full solution: <a href="intent://my_host#Intent;scheme=my_scheme;action=my_act‌​ion;end">Link to my stuff</a> thanks for your help.

Hey, if I want to open a web site in google chrome for android how it would be? What should I put in intent? and in my action?

@MatheusOliveira please open a new question. Asking your question in a comment on this answer isn't the way to get an answer. If you ask a new question you are more likely to get some attention.

My two cents ....If the link goes inside an HTML email does not work because Gmail remove this kind of hiperlinks.

[aolphn]

you can invoke js method to do this. Code as follow:
