使用隐式意图时，活动没有出现在选择器对话框中

Question

I would like to start MyBrowser, an application that show web pages like the built-in Browser app, from another application, IntentsLab.

I followed Launch custom android application from android browser to setup the intent, and also the official Intent and Intent-filters guide which does says "You need to include CATEGORY_DEFAULT to receive implicit intents".

So my intent-filter is so written:

        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.categroy.DEFAULT" />
            <data android:scheme="http" />
        </intent-filter>

The code of the parent activity in IntentsLab to start the new activity is:

    Intent baseIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
    String title = "Use Browser";        
    Intent chooserIntent = Intent.createChooser(baseIntent, title);        
    if(chooserIntent != null)   startActivity(chooserIntent);

The MyBrowser application does not show up on the chooser dialog. However, when I created an Activity inside the IntentsLab and added to it a same intent-filter, this activity shows up in the chooser dialog. Is there anything wrong with the code? Or is there any difference between implicit intent towards Activities in a same Application with those in a different one?

Provided my AndroidManifest.xml for the MyBrowserActivity. It works perfectly for me. Even I am doing the coursera Android programming class :)

 <activity android:name=".MyBrowserActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <data android:scheme="http" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> <!-- TODO - Add necessary intent filter information so that this Activity will accept Intents with the action "android.intent.action.VIEW" and with an "http" schemed URL --> </activity>
