String limit on android studio

Question

i am really new to Android Studio and java programming.

im trying to create a new project, just to experimenting and learning.

this app there is long text and i using string to format it and also as resources.

however, after 1400+ text and formatting, the activity crash.

may i know is there some limit on string resources ?

and what is the way to overcome the problems ?

i figured out to use raw text, but on my current understanding, there is no way to format it like strings.

really appreciate if anyone can help.

\edit

here is the error

What is the error listed in the error logs when the activity crashes? That should help point you toward if this is an issue with a text limit or not. — WOUNDEDStevenJones, Feb 19 '21 at 18:11
I will check it soon, but for now, i sure it is something with limit as, there is no error showing on android studio, and i trying to add few lines of text with no format, it crash too. If it true because of text limit, may i know some ways to overcome it? — Mr Learning, Feb 19 '21 at 18:17
I'm not sure, but when an activity crashes in Android Studio in debug mode, you will be able to view the error in the logs (https://stackoverflow.com/questions/19784877/how-to-find-the-logs-on-android-studio) that will tell you the exact line that caused it to crash along with an error message (which can easily be searched for online for more details if needed). Without these logs added to your question, it's hard to guess what might be causing this issue. — WOUNDEDStevenJones, Feb 19 '21 at 18:21
There's no inherent "string limit" or anything of that kind. Chances are that your application runs out of memory or some other resources. What exactly it is would become visible if we could see your logs, so please provide what WOUNDEDStevenJones asks for. — Joachim Sauer, Feb 19 '21 at 18:25
Also providing a minimal sample code that can reproduce such error maybe helpful. — hata, Feb 20 '21 at 11:39

String.length() method returns the length of the string. The length of the string is equal to the number of Unicode units in the string. The Java platform uses the UTF-16 representation in char arrays (each character takes two bytes), String, and StringBuffer classes.

The method returns the length which is of type int. So, the String maximum size is the same as the range of integer data type. The maximum length that would be returned by the method would be Integer.MAX_VALUE.

The size of int in Java is 4 bytes (included a signed bit, i.e. MSB). The range of integer data type is -2³¹ to 2³¹-1 (-2147483648 to 2147483647). Remember that we cannot use negative values for indexing. The indexing is done within the maximum range. It means that we cannot store the 2147483648th character. Therefore, the maximum length of String in Java is 0 to 2147483647. So, we can have a String with the length of 2,147,483,647 characters, theoretically.

import java.util.Arrays;

class StringMaxSize {
    public static void main(String args[]) {
        for (int i = 0; i < 1000; i++) {
            try {
                //Integer.MAX_VALUE is a constant that stores the maximum possible value for any integer variable  
                char[] array = new char[Integer.MAX_VALUE - i];
                //assign the specified data value to each element   
                Arrays.fill(array, 'a');
                //creating a constructor of the String class and parses an array into it  
                String str = new String(array);
                //determines and print the length of the string  
                System.out.println(str.length());
            } catch (Throwable e) {
                // returns the detail message string of this throwable  
                System.out.println(e.getMessage());
                //prints the maximum value  
                System.out.println("Last: " + (Integer.MAX_VALUE - i));
                System.out.println("Last: " + i);
            }
        }
    }
}

Output:

So, 1400+ text is not the actual issue.
