如何在Android上读取大文本文件？

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class ReadLargeTextFile {
    public static String readTextFile(String filePath) {
        StringBuilder stringBuilder = new StringBuilder();
        BufferedReader bufferedReader = null;

        try {
            bufferedReader = new BufferedReader(new FileReader(filePath));
            String line;

            while ((line = bufferedReader.readLine()) != null) {
                stringBuilder.append(line);
                stringBuilder.append("\n");
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (bufferedReader != null) {
                try {
                    bufferedReader.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }

        return stringBuilder.toString();
    }
}
