    Is the other app you’re launching made by you? If so, you can tell Android to launch it when a certain URL is encountered, using app links:

    https://developer.android.com/training/app-links#android-app-links

    You can add an HTTP(S) URL to your manifest file. When the user has your app installed opening the URL will open the app, and if your app is not installed, they are redirected to the HTTP(S) site in their browser (which may redirect them to the Play Store or some other place.

    If not, maybe try to clarify the text in your question a little bit. It’s a bit confusing to read.
