How to open specific activity for particular id by clicking from external link

I added App link assistant in my app to open particular activity from an external link. Now I've the following code in my DataDetailActivity.

   Intent appLinkIntent = getIntent();
    String appLinkAction = appLinkIntent.getAction();
    Uri appLinkData = appLinkIntent.getData();
    if(appLinkData != null)
    {
        String dataId = appLinkData.getLastPathSegment();

        Intent resultIntent = new Intent(this, DataDetailActivity.class);
        startActivity(resultIntent);

    }

I would like to open particular DataDetailActivity. But this does throws error. Where do I have to pass dataId in the intent?

Note: We have Default HomeScreen in the app that has Login To FB button. So Do I have to write down this code in HomeScreenActivity and pass intent to DatadetailAcvity.java? If yes then how Do I tell to DataDetailScreen for particular data(If i have id)?

Any help would be appreciated.

HomeScreenActivity

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_home);
    checkDeepLink();
}

private void checkDeepLink(){
    if (getIntent() != null && getIntent().getData() != null) {
        Uri data = getIntent().getData();
        String scheme = data.getScheme();
        String host = data.getHost();
        String param = data.getQuery();
        Log.d("DeepLink","Schema : " + scheme);
        Log.d("DeepLink","Host : " + host);
        Log.d("DeepLink","param : " + host);

        if (host.equals("page_details")){
            Intent intent = new Intent(this,DatadetailAcvity.class);
            intent.putExtra("detail_id",Long.valueOf(data.getQueryParameter("detail_id")));  // URL query values as string, you need to parse string to long.
            startActivity(intent);
        }else{
          // ... other logic
        }
    }
}

DeepLink

scheme://host?pama_name=value&other_param_name=value

Example: 

 somescheme://page_details?detail_id=2

DatadetailAcvity

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_data_detail);
    if (getIntent() !=null) {

    }

Without error info,but if you want pass data through deep linking, you could use query parameters. Suppose url is https://www.example.com/example?param1=hello

Then

Intent intent = getIntent();
Uri data = intent.getData();
String param1 = data.getQueryParameter("param1");
