//使用chooserIntent
    private void startImplicitActivation() {

        Log.i(TAG, "Entered startImplicitActivation()");

        // TODO - Create a base intent for viewing a URL
        // (HINT:  second parameter uses Uri.parse())
        Uri myUri = Uri.parse(URL);
        Intent baseIntent = new Intent(Intent.ACTION_VIEW, myUri);
        // TODO - Create a chooser intent, for choosing which Activity
        // will carry out the baseIntent
        // (HINT: Use the Intent class' createChooser() method)
        Intent chooserIntent = Intent.createChooser(baseIntent, "Display this url via ..");

        Log.i(TAG,"Chooser Intent Action:" + chooserIntent.getAction());

        // TODO - Start the chooser Activity, using the chooser intent
        startActivity(chooserIntent);

    }

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