빈 메시지로 인해 오류가 발생했습니다.

여기입니다

String info = ""; 
    String sms = info;

아래 코드 뒤에

상기 info 및 sms는 동일하다. 이 작업을 수행 한 후 그러나 :

info += "Monthly Wifi Data Usage Amount:\t";

새로운 문자열 생성 info에 할당을, 그래서 info 및 sms 더 이상 동일하지 않습니다. sms은 여전히 비어 있으며 IllegalArgumentException을 얻은 이유가 있습니다.

코드에서 info을 제거하고 sms 변수 만 사용하면됩니다. StringBuilder

제안 된 방법 (위의 업데이트 된 소스 코드 추가)을 시도했지만 지금 널 포인터 예외로 끝납니다 (도움 주셔서 감사합니다!) –

@ user2478682 아마도 sms 메시지 일 겁니다. 너무 큽니다. 더 작은 것으로 사용해보십시오. – andrew

그게 다야! 감사합니다!! –
