Android Stüdyo Sms Has Stopped Hatası acil yardım lütfen ...

Merhaba herkese sms gönderen basit bir uygulama yapmak istedim fakat sms göndermek için tıklayınız butonuna tıkladığım zaman Unfortunately, sms has stopped diye bir hata alıyorum.

Hatanın burada olduğunu düşünüyorum

Çözüm için şimdiden teşekkürler herkese.
