Android从字符串文本中提取句子

Question

I'm working on a recipe application on Android. My recipe source(Rest API) is basically a service that allows users to manually submit recipes to the site, and that's what they archive and return to the client in the form of JSON.

Basically, the "Directions" portion of the JSON just returns one big blob of text as the instructions. It is not formatted excepted for line breaks.

To give you an idea, here's an example of some instructions returned

Place cast iron skillet in oven and heat oven to 500 degrees. Bring steak(s) to room temperature. Season both sides with salt, pepper, garlic powder, and cayenne pepper. When oven reaches temperature, remove pan and place on range over high heat. Immediately place steak in the middle of hot, dry pan. Cook 30 seconds without moving. Turn with tongs and cook another 30 seconds, then put the pan straight into the oven for 2 minutes. Flip steak and cook for another 2 minutes. (This time is for medium rare steaks. If you prefer medium, add a minute to both of the oven turns.) Remove steak from pan, cover loosely with foil, and rest for 2 minutes. Serve whole or slice thin and fan onto plate.

I need to break this long string of text into sentences so that I display each in a custom view that I've designed.

Does anyone know of any libraries that I can use to accomplish this? I understand that English language detection may be difficult, and after research I'm learning that this is not really doable with regular expressions, so I'm looking at my options at this point. If anyone knows of anything, please feel free to share! Thanks as usual guys.

    String paragraph = "Place cast iron skillet in oven and heat oven to 500 degrees. Bring steak(s) to room temperature. Season both sides with salt, pepper, garlic powder, and cayenne pepper.

    Pattern sentencePatterns = Pattern.compile("[^.!?\\s][^.!?]*(?:[.!?](?!['\"]?\\s|$)[^.!?]*)*[.!?]?['\"]?(?=\\s|$)", Pattern.MULTILINE | Pattern.COMMENTS);
    Matcher match = sentencePatterns.matcher(paragraph);
    while (match.find()) {
        System.out.println(match.group());
    }
