About starting Android app from an URL - android

I am trying to figure out how to start an app from a URL, and how I should write that URL.
I have the following code in my AndroidManifest:
<activity android:name=".MyActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"></action>
<action android:name="android.intent.action.VIEW"></action>
<category android:name="android.intent.category.LAUNCHER"></category>
<category android:name="android.intent.category.DEFAULT"></category>
<category android:name="android.intent.category.BROWSABLE"></category>
<data android:host="my.app" android:scheme="http"></data>
</intent-filter>
</activity>
I used a URL as explained in this answer, but nothing happens.
Please let me know if my intent is well written, and how I should write the URL that calls that app, and note that I need to call my "Main" Activity.


You need to have two <intent-filter> elements for this <activity>. One will be for MAIN and LAUNCHER. The other will be for VIEW, BROWSABLE/DEFAULT, and your <data> element:
<activity android:name=".MyActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"></action>
<category android:name="android.intent.category.LAUNCHER"></category>
</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="my.app" android:scheme="http"></data>
</intent-filter>
</activity>
Then, http://my.app should launch your activity.

Using Deep link to open app with external link

I am trying to make my android app open when the user presses on a link to our website.
I was following this documentation but it is not working for me as it always opens the browser instead of asking if I would like to continue with the browser or the app. What am I doing wrong?
here is my manifest
<activity
android:name=".presentation.MainActivity"
android:exported="true"
android:label="#string/app_name"
android:theme="#style/Theme.LegendaryCollectionsAndroid.NoActionBar"
android:allowTaskReparenting="true"
>
<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.legendarycollections.net"
android:path="/reset"
android:scheme="https"></data>
</intent-filter>
</activity>

Browser can't open an app from a browser using deeplink

android:screenOrientation="portrait"
android:windowSoftInputMode="adjustPan">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
<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="http"
android:host="example.com"
android:pathPrefix="/"/>

Android 6 - cannot open app url from chrome

I had setup intent filter in manifest.xml, such as follows:
<activity
android:name="indexgifto.android.ui.viewcontrollers.SplashScreenActivity"
android:label="#string/application_name"
android:launchMode="singleTop"
android:windowSoftInputMode="adjustNothing"
android:theme="#android:style/Theme.Translucent.NoTitleBar"
android:screenOrientation="portrait" >
<intent-filter>
<data android:scheme="gifto"/>
<data android:scheme="http" />
<data android:host="www.gifto.net"/>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
When I execute 'am start http://www.gifto.net/go.php?c=xlh201' application successfully opens with required data. But, when same URL opened via Chrome, just server page opens. In the android 4 in both cases my app was able to start from this url. What I must fix in android 6?

Chrome for Android, versions 25 and later, you should implement a user gesture to launch the app via a custom scheme, or use the “intent:” syntax described in this article.
https://developer.chrome.com/multidevice/android/intents

this worked for me you to try once if worked for u.
<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" android:pathPrefix="http"></data>
</intent-filter>

how to launch an android app with custom url scheme

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>

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.

Application not being displayed in the list of default apps on device

I am trying to write a photo viewer application and have put the below in my Manifest file
<activity
android:name="com.example.testimageintent.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">
<data android:mimeType="image/*"/>
</category>
</action>
</intent-filter>
</activity>
The idea was to list this app in the list of available applications when the user tries to open an image from the file browser.
Somehow my app is never listed in that list. I can still see the gallery and other apps in the list but my app never appears.
Any pointers to what i might be doing wrong?

I think you are missing
<action android:name="android.intent.action.SEND" />
in your <intent-filter>
Define it to look like this:
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*"/>
</intent-filter>

Sorry Guys, it's my mistake. I have nested the Action, Category and the Data blocks.
They should be independent of each other.
It works fine once i have them as individual tags like below:
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="image/*"/>
