Interactive filter for media player (Youtube video game)

I have developed my own media player, and I want it to be opened from my application when I want to watch a video from Youtube. At the very least, the view should have a list of media applications, and I would have to select my application from the list. I don't know much about intent filters. How can I provide this in my manifest file? I am working to do this for local files for training, but I have not been able to do this yet. I really need your help:/

If you look at the intent filter, which uses the official youtube app, you will see the following:

<activity android:name="Player"> <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="youtube.com" android:pathPrefix="/watch" /> <data android:scheme="https" android:host="youtube.com" android:pathPrefix="/watch" /> </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="*.youtube.com" android:pathPrefix="/watch" /> <data android:scheme="https" android:host="*.youtube.com" android:pathPrefix="/watch" /> </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="www.youtube.com" android:pathPrefix="/v/" /> <data android:scheme="https" android:host="www.youtube.com" android:pathPrefix="/v/" /> <data android:scheme="http" android:host="www.youtube.com" android:pathPrefix="/e/" /> <data android:scheme="https" android:host="www.youtube.com" android:pathPrefix="/e/" /> <data android:scheme="http" android:host="www.youtube.com" android:pathPrefix="/embed/" /> <data android:scheme="https" android:host="www.youtube.com" android:pathPrefix="/embed/" /> </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="vnd.youtube" /> </intent-filter> </activity>

To get the video id, you can parse the line from which you get:

 Uri uri = this.getIntent().getData();

As you can see, there is no filter for youtu.be, but you can add:

 <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="youtu.be" /> <data android:scheme="https" android:host="youtu.be" /> </intent-filter>

I am updating the H9kDroid answer, which is from 2011. These are the corresponding decompiled intent filters from the latest YouTube APK at that moment (January 11, 2015).

 <activity-alias android:theme="@01030055" android:name="com.google.android.youtube.UrlActivity" android:exported="true" android:targetActivity="com.google.android.apps.youtube.app.honeycomb.Shell$UrlActivity"> <intent-filter> <action android:name="android.intent.action.VIEW"> </action> <action android:name="android.media.action.MEDIA_PLAY_FROM_SEARCH"> </action> <action android:name="android.nfc.action.NDEF_DISCOVERED"> </action> <category android:name="android.intent.category.DEFAULT"> </category> <category android:name="android.intent.category.BROWSABLE"> </category> <data android:scheme="http"> </data> <data android:scheme="https"> </data> <data android:host="youtube.com"> </data> <data android:host="www.youtube.com"> </data> <data android:host="m.youtube.com"> </data> <data android:host="youtu.be"> </data> <data android:pathPattern=".*"> </data> </intent-filter> <intent-filter> <action android:name="android.intent.action.VIEW"> </action> <action android:name="android.media.action.MEDIA_PLAY_FROM_SEARCH"> </action> <action android:name="android.nfc.action.NDEF_DISCOVERED"> </action> <category android:name="android.intent.category.DEFAULT"> </category> <category android:name="android.intent.category.BROWSABLE"> </category> <data android:scheme="vnd.youtube"> </data> <data android:scheme="vnd.youtube.launch"> </data> </intent-filter> </activity-alias>

And this is how these intentions seem to understand the code. Sorry it's confusing, but still useful in my case:

} private glb(List paramList, Map paramMap, int paramInt) { this.a = Collections.unmodifiableList((List)bc(paramList, "videoIds can not be null")); if (!this.a.isEmpty()) {} for (boolean bool = true;;
