Deep link into an app while the app is already running in the background

Question

I have implemented a DeeplinkActivity to catch the intent-filter data scheme and open an activity. The issue I am having is the app is already open in the background and then the user clicks a deep link to open the home screen activity. If the user presses back to get out of the app it will go to what was running in the background. I wanted it to just back out of the app.

I have tried this.

        Intent intent = new Intent(this, LaunchActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK); 
        startActivity(intent);

But this does not work. Any suggestions?

Answer 1

I have just had this problem fixed myself.

First you need to go to the manifest and set launchMode to "singleTask", this will prevent your app from opening a new instance entirely.

Second you need to go the Activity that's accepting that intent filter and override this method

override fun onNewIntent(intent: Intent?) {
    super.onNewIntent(intent)
}

now by using the new intent here you will have access to the deep link and be able to route to where you need to within your app.
