androidstudio错误:常量字符串过长的解决方式

  String provsData = new GetJsonDataUtil().getJson(activity, "provsData.json");//获取assets目录下的json文件数据
  String distsData = new GetJsonDataUtil().getJson(activity, "distsData.json");//获取assets目录下的json文件数据
  String citysData = new GetJsonDataUtil().getJson(activity, "citysData.json");//获取assets目录下的json文件数据

public class GetJsonDataUtil {


  public String getJson(Context context, String fileName) {

    StringBuilder stringBuilder = new StringBuilder();
    try {
      AssetManager assetManager = context.getAssets();
      BufferedReader bf = new BufferedReader(new InputStreamReader(
          assetManager.open(fileName)));
      String line;
      while ((line = bf.readLine()) != null) {
        stringBuilder.append(line);
      }
    } catch (IOException e) {
      e.printStackTrace();
    }
    return stringBuilder.toString();
  }
}

String str = "67890123456789...0123456789";//由于字符串长度太长，所以省略一部分，长度是65534
str = "5" + str;
System.out.println(str.length());  //编译通过，运行结果为:65535

CONSTANT_Utf8_info {
  u1 tag;
  u2 length;
  u1 bytes[length];
