Add an intent-filter in the Manifest so your app can respond to map URLs:

<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="maps.google.com" />
    <data android:scheme="https" android:host="maps.google.com" />
    <data android:scheme="geo"/>
</intent-filter>

Once in your app, you can retrieve the URI using this code:

protected void onCreate(Bundle savedInstanceState) {
    Intent intent = getIntent();  
    Uri data = intent.getData(); // Here you will receive the URI

    // ...
}
