죄송 합니다만 관련 logcat 출력을 게시 한 것으로 보지 않습니다. 'com.xenom.text'에 관한 몇 가지 예외를 찾을 수 있습니까? – ninetwozero

당신이 button1 인스턴스를 인스턴스화하는? 로그가 말하는 무슨 당신은

button1 = (Button)findViewById(R.id.myButton);

같은 뭔가가 필요? null 변수 참조에서 클릭 리스너를 설정하려고하면 라인에 NullPointerException이 표시되는 것 같습니다.

OK 위의 코드가 여전히 유효합니다. – Aman

버튼을 초기화해야합니다. 먼저, 글로벌 변수 button1을 Button으로 변경하십시오. 그런 다음, 된 setContentView (R.layout.main) 후,이 전화 :

button1 = (Button)findViewById(R.id.button);

UPDATE : 당신이 mText1가 null의 경우에도 Uri.encode(mText1)을하려고하기 때문에

오류도있을 수 있습니다.
