Share app link with Whatsapp

Question

Good morning ! How do I share a link from my app with a contact in Whatsapp ? Searching on the internet I was able to form this code (it is without successful tests because I’m still just testing it) that when recording an activity in firebase I open a library full of apps to share a link, but so far I can only share the text: "User x has created a new activity, what I’d like is for this message to have a link that directs the person directly to the profile or to any screen of my app for example. Follows code (from Activity’s Website) that shares the text cited above:

public void compartilharAtividade(){

    Branch branch = Branch.getInstance();
    //Uri mainUri = getActivity().getIntent().getData();
    Intent share = new Intent(android.content.Intent.ACTION_SEND);
    share.setType("text/plain");
    share.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);

    share.putExtra(Intent.EXTRA_SUBJECT, "Teste de compartilhamento APP");
    share.putExtra(Intent.EXTRA_TEXT, "O usuario "+ nomeUsuario + " criou uma nova atividade! Teste de Link: "+ branch);
    //share.putExtra(Intent.EXTRA_PACKAGE_NAME, "com.ramattecgmail.rafah.studying");

    startActivity(Intent.createChooser(share, "Teste de compartilhamento"));

}

in Main Activity I call the branch this way:

@Override
public void onStart() {
    super.onStart();
    Branch branch = Branch.getInstance();

    branch.initSession(new Branch.BranchUniversalReferralInitListener() {
        @Override
        public void onInitFinished(BranchUniversalObject branchUniversalObject, LinkProperties linkProperties, BranchError error) {
            if (error == null) {
                // params are the deep linked params associated with the link that the user clicked -> was re-directed to this app
                // params will be empty if no data found
                // ... insert custom logic here ...
            } else {
                Log.i("MyApp", error.getMessage());
            }
        }
    }, this.getIntent().getData(), this);
}

@Override
public void onNewIntent(Intent intent) {
    this.setIntent(intent);
}

In short, I need my app to send the Uri itself, or at least recover this Uri that I can’t even do in Main Activity... Thanks in advance!

Good you will have to create a deep link and add in the manifest of your Activity, for example:

<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:host="www.seusite.com"
    android:pathPrefix="/home"
    android:scheme="https"/>
</intent-filter>

Where is the host, you will add your URL, to redirect to your app link, but first of all do not forget to add android-app://yourpackage name/http/www.seusite.com/home/ so it recognizes the package of your app.

This link will certainly help you understand a little more about deep link:
