Question

I have program with maps. When user click url link containing ‘mymaps.com’ – my program shows in chooser dialog as alternative of web browser.
I want to do same when user click link to google maps /web or application generated/.
I have found different url formats:

• http://m.google.com/u/m/zIOcsV
• http://maps.google.com/maps?q=45.089036,+-106.347656&num=1&t=h&vpsrc=0&ie=UTF8&z=4&iwloc=A

I suppouse there are other formats too.
Does anybody know how to intercept all formats?

Answer 1

Use an intent filter! See here for more info : http://developer.android.com/guide/topics/intents/intents-filters.html

In your android manifest, add the following in your tag for the activity you want to open :

<intent-filter>
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:scheme="http" android:host="maps.google.maps" android:pathPrefix="/maps" />
</intent-filter>

Then in your Activity
create a method called : handleIntent like so

private void handleIntent(Intent newIntent) {
      Uri myuri = newIntent.getData();
      (then use myuri to get your parameters such as q, num, etc)
      (then show your map or whatever else you like with that data)

}

in your onCreate you will need to call handleIntent like so

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    (init stuff would go here)
    handleIntent(getIntent());
}

(optional) You may need to override the onNewIntent like so (just in case your AndroidManifest activity configchanges property is tweaked)

@Override 
protected void onNewIntent(Intent newIntent) {
    setIntent(newIntent);
    handleIntent(newIntent);
}
