Just call all of the functions on your image file at once, then combine the results using something like zip in RXJava.
Alternatively, you could nest the results (e.g. call FirebaseVision.getInstance().onDeviceTextRecognizer.processImage(image)
inside the onSuccessListener
of another function), although this will take much longer to complete all.
If you provide code of your existing attempts, StackOverflow can help further.
