How to make app link work for facebook for android only with open graph stroy

Question

I have an android only app. It has a feature to share an open graph story in facebook. I have managed that part. Now I want app link integration between my app and facebook. But the documention in facebook is very confusing. I also tried the app link host tool and created the app link from web-based App Links tool When i tried to open it from my android phone it says

This is only available from via the MyAppName app. Do you want to install it from the Play Store?

but my app is already installed. Below is the code i used to share.

ShareOpenGraphObject object = new ShareOpenGraphObject.Builder()
            .putString("og:type", "mynamespace:post")
            .putString("og:title", title)
            .putString("og:description", description)
            .putString("og:url","link provided by  api link tool")
            .putString("al:android:url","myapp://abc/123")
            .putString("al:android:app_name",getString(R.string.app_name))
            .putString("al:android:package","com.myapp")
            .build();

    ShareOpenGraphAction action = new ShareOpenGraphAction.Builder()
            .setActionType("mynamespace:share")
            .putObject("post", object)
            .build();

    ShareOpenGraphContent content = new ShareOpenGraphContent.Builder()
            .setPreviewPropertyName("post")
            .setAction(action)
            .build();

mShareDialog.show(content);

I dont want to use other libraries like branch.io or parse cloud service.

NOTE The app is in development mode
