How To Avoid Handling A Deep Link Twice On Android?

I have an android test app that handles a custom URL deep link (e.g. myapp://xxx/yyy) inside onResume as follows: if (intent.getAction() != Intent.ACTION_VIEW) return; String data

Solution 1:

Based on the comments above, the solution that works best seems to be:

1. place the URL processing code inside onCreate(state)
2. only process the URL if state == null

Code sample:

voidonCreate(Bundle savedInstanceState) {
    if (savedInstanceState == null) {
        if (intent.getAction() == Intent.ACTION_VIEW) {
            String data = intent.getDataString();
            if (data != null) {
                // ... process URL in 'data'
            }
        }
    }
}

Solution 2:

After processing the intent use setIntent(null);

Solution 3:

I think you should process the url in OnNewIntent and onCreate(neither will be call when become active from background), to avoid multiple processing when rotating, there are two solutions to me:

Solution 1: In onCreate, ignore it if savedInstanceState is no null, This solution based on multiple calling is from rotation, and only need changes on app side.

Solution 2: Make the deeplink url dynamic, which changes every time（like myapp://xxx/yyy?stamp=xxxx）, and you can check if the url is already processed. This solution can take any case, but need you modify the url ( maybe from server side ).
