how to launch an android app with custom url scheme

Question

I want to launch my app from a custom URL scheme. I checked the deep links section on dev android and here is a snippet of my code. This doesnt seem to fire though with a URL that looks like : myApp://?host=myhost.com

Manifest :

<intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:scheme="myApp" /> </intent-filter>

In the activity which is my main activity, i have :

Intent intent = getIntent(); Uri uri = intent.getData(); if (uri != null) { String host = uri.getQueryParameter("host"); }

The app does not launch when i have email that has the url as a hyperlink. Also, what would be a good way to test this ?

Try this, edit your IntentFilter

<intent-filter> <action android:name="android.intent.action.VIEW"></action> <category android:name="android.intent.category.DEFAULT"></category> <category android:name="android.intent.category.BROWSABLE"></category> <data android:host="www.youtube.com" android:scheme="http"></data> </intent-filter>

EDIT

<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"></action> <category android:name="android.intent.category.DEFAULT"></category> <category android:name="android.intent.category.BROWSABLE"></category> <data android:host="www.youtube.com" android:scheme="http"></data> </intent-filter>

My action is MAIN which is the entry pt. into the app. Wouldnt it work with MAIN ?
Okay I've edited my question. This is how you can have two separate IntentFilters.
Cool thanks but i found that you can combine them into a single intent filter and order them.
I am able to successfully launch apps with URL style calls, however, its launching the app from within my own app, not in a new window. What intent can I use to force the app to a new window?

The browser converts the scheme to lowercase, so you need to change the data tag to

<data android:scheme="myapp"/>

k it looks like ACTION_VIEW is a must to support custom URI schemes. I can add VIEW and MAIN though which gets it to work.
