Hide an Android/iOS app and make it launchable only by url

Question

I am working on an application that should communicate with my web app to retrieve some data.

So I have application A which is a web app. There is this other application B which is Native and is not designe to access internet.

Application B connects to a device using blutooth protocol and gets data from a remote Device.

app A calls app B with its reverse url (B://callmeBack/?appName=A) And then app B interprets the callmeBack arg and calls A (A://?data=someData)

App A can call all pages of B (B://pageName/?data=someData)

This works fine. Since app B doesn't communicate with internet I want B to be hidden, so that users always use A to go to B, and B to give back data to A when A asks B.

App A can be used every where and give richer content.

How can I make B (native app) hidden and only laounchble from A for iOS and Android?

Is it something I need to add in the B AndroidManifest.xml and the equivalent in iOS ?

Thank you for your help!

If I understand your question well, you should remove the intent filter which is used to tell the launcher, that it should be displayed from your AndroidManifest.xml. Typically it looks like this:

<intent-filter>
    <action android:name="android.intent.action.MAIN"/>
    <category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
