Sending a token from one app to another avoiding the intent chooser

Question

I have the following requirement: I have 2 apps with the same sign key.

1. Login app A and get token(this toke is just a string)
2. From app A open and pass the token to B <- HOW TO DO THIS
3. Receive the token and login in B and none other app.

I'm reading this: https://developer.android.com/training/sharing/index.html and I can't find how send data from one app to an specific app.

I don't want the chooser(https://stackoverflow.com/a/41185310/2139691) let the user send the token to any other app.

Answer 1

You can try find passing data through intent?

Intent launchIntent = 
getPackageManager().getLaunchIntentForPackage("com.package.address");

launchIntent.putExtra("data", data);

startActivity(launchIntent);
