Intent filter not working properly

The URL redirects to another URL which in turn is supposed to redirect back to my app, but it doesn't. Am I missing something here?
Actual redirect URL is: https://mpivchev.github.io/Reddit-App/redirect?state=XXXXXX&code=XXXXXX
Intent filter:
<activity android:name=".LoginActivity">
<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="mpivchev.github.io"
android:scheme="https"
android:path="/Reddit-App/redirect" />
</intent-filter>
</activity>
WebView stays on the redirect page instead of returning back to the app:

Link from Android browser to my application not working

I want from the android browser be able to launch my application if it's installed, or launch my website in the other case.
So in order to make it work, I put :
<activity android:name=".MMLogin" android:label="MeetMe" android:theme="#android:style/Theme.NoTitleBar" android:screenOrientation="portrait">
<intent-filter>
<data android:scheme="http" android:host="meet-me.com" android:path="/signin" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.BROWSABLE"/>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
in the Manifest, and I created a dummy link to test; and it's not working.
I've tried with and without: BROWSABLE and DEFAULT
I've tried with meetme://datas and change the scheme; nothing worked.
I used threads on stackoverflow like :
Launch custom android application from android browser
What am I doing wrong, or is there a special thing to do to make it work ?
My application suppports from API 7.
Cheers

I used :
Intent Filter to Launch My Activity when custom URI is clicked, I think what was missing is this block :
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="android.intent.action.EDIT" />
<action android:name="android.intent.action.PICK" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="application/myapp" />
</intent-filter>

Android Intent-Filter for Multi Screen

I want to launch my application from web browser in Android using Intent-Filter based on scheme, host in the DATA tag like this.
<activity android:name=".activity.LogoActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".activity.phone.MainActivityPhone" android:configChanges="orientation|keyboard"
android:launchMode="singleTask">
<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" android:host="mystore" />
</intent-filter>
</activity>
<activity android:name=".activity.tablet.MainActivityTablet" android:configChanges="orientation|keyboard"
android:launchMode="singleTask">
<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" android:host="mystore" />
</intent-filter>
</activity>
As you see, There are two Main Activities for phone and tablet, and in LogoActivity determine which Main Activity will be opened by screen size. But the problem is when user clicks my://mystore link in web browser, there are two choices to launch that MainActivtyPhone and MainActivityTablet.
What I want is there is only one proper intent-filter works for uri my://mystore .
Any help? Thanks.

On the first run of your application, use PackageManager to disable the activity you do not want to use.
Please do not invent custom schemes. Please use HTTP URLs instead:
<data android:scheme="http" android:host="yourdomain.com" android:path="/something/or/another" />
That way, you can actually put a real Web page at http://yourdomain.com/something/or/another, so if somebody gets your link but does not have your app installed, they will see your Web page, instead of getting an error.
Also, please remove android:configChanges, or handle all configuration changes.

Could not launch application by calling a URL from Android Browser

There are many answers in stackoverflow showing how to lauch app from a web browser ,but I am not sure what went wrong with my code, that never seems to be doing the intended.
I am trying to launch my app by a URL from any other app like web browser,initially
my manifest file looks like this
<activity android:name=".Main">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<data android:scheme="http" android:host="ebay.com" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
And When I typed http://ebay.com in the browser that never started my app.Obviously,how does the browser know about my app?,then i tried the other way around and added another Activity called MyActivity and altered the manifest file as
<activity android:name=".Main">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MyActivity">
<intent-filter>
<data android:scheme="http" android:host="ebay.com" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
</activity>
and tried in my Main Activity
startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("http://mycityway.com")));
Thus producing the intended result.I can also start another application Activity using this method.
But most of the answers here says that the later is possible.What is the mistake i am doing,I couldn't launch my app from browser.Please guide me.

And When I typed http://ebay.com in the browser that never started my
app.
It gets started when a matching link is clicked not when you type the url in the browser.
Try it by sending yourself an email containing http://ebay.com and click the link in the email application.

android custom url scheme..?

Im trying to create my own url scheme so my android app can get called via an URL but for now I dont have a success.
Im trying to have this url to work : cedemo://com.cedemo.scan?X=toto
Here is part of my manifest file :
<activity android:name=".Gallery1" android:label="#string/app_name" android:launchMode="singleTask" android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.GALLERY" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="cedemo" android:host="com.cedemo.scan" />
</intent-filter>
</activity>
Does anyone can help telling me what is wrong ?
Also, if someone find what is wrong, can someone tell me how I read the "X" variable from inside the android code from my app ?
Update:
Update: I did the modification of the action (as advised in one of the answers) and it's worked fine. The thing is that I still cannot get the url variable value. Here is the code I tried.
final Intent intent = getIntent();
final String myScheme=intent.getScheme();
final Bundle myBundle=intent.getExtras();
final boolean inContestKey;
if (myBundle != null) {
inContestKey=myBundle.containsKey("inContest");
}
final Uri myURI=intent.getData();
final String value;
if (myURI != null) {
value = myURI.getQueryParameter("inContest");
}
But I receiving null from all the functions… what else can i do?
May be I should explain better the context of my software:
My software is started
My software launch then the browser
the user click a link in the browser and the browser go to the url scheme, back to the software with a variable "X" (for example)
the software should read the variable "X"
But in my case : myScheme, myBundle, myURI are set to null.
Any ideas ?
Update:
I found the answer is that you have to be in the main activity to do that.

I think the problem is with the Action you defined.
There is a "android.intent.action.VIEW" which is what I think you want.
<activity android:name=".Gallery1" android:label="#string/app_name" android:launchMode="singleTask" android:screenOrientation="portrait">
<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="cedemo" android:host="com.cedemo.scan" />
</intent-filter>
</activity>
Try that and I bet will resolve correctly. I only made this assumption because you included the browsable category which is usually used by the Browser, which does not know of any of your custom actions. If you do want the GALLERY action as you have implied then just create 2 filters
<activity android:name=".Gallery1" android:label="#string/app_name" android:launchMode="singleTask" android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.GALLERY" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="cedemo" android:host="com.cedemo.scan" />
</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="cedemo" android:host="com.cedemo.scan" />
</intent-filter>
</activity>
So within the contents of your activity you can do something like:
// Value should be "toto" as in your example
String value = getData().getQueryParameter("X");

What finally fixed things for me was changing the order of the XML elements. Specifically, swapping the data and action rows so data is before action made it start working.
<intent-filter>
<data android:scheme="myappname" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.BROWSABLE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
And for completeness, my link in the html is "myappname://noop".

One more thing, i would like to throw light. Initially it was not working for me because i was using Main/Launcher tags before View/Default/Browsable/data.
Once i changed the order it started working fine.
i.e Initially not working code
<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" />
<data android:scheme="myapp" />
</intent-filter>
correct code order
<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="myapp" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
and way to test for android is very simple.
Make any html file insert
test to launch myapp <br /><br />
just open this html file and click on test to .... :-)
