Here is my code, When any message will come then my BroadCastReceiver will call. From that I started service for getting unread messages from inbox and that messages I will send as a message.
I got the message from inbox but when I send that messages as a message then I got “Nullpointer Exception”.
Please anyone can tell me at where I am wrong?
EDIT:
I found that when I send length of text in message then it will give me NullPointer Exception. As I searched on google I found that is problrm resolved by using sendMultipartTextMessage instaed of using sendTextMessage. But I already used that method so why I get this error?
Thanks.
Hello I got the solution. I feel glad to share with you people. I used
ArrayList messages = sms.divideMessage(message);
