This post covers a simple scenario where we have a web page (for example, on our organization’s mobile site) that we would like to link back to the mobile app.

In our AndroidManifest.xml, create an intent-filter element as follows:

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

If you place this under the main element representing your app, then the following link will invoke your app.
Now the link ourorg:// will link back to the app.

There’s a lot more that you can do with the intent-filter. For now, we’re just covering a simple case here.
