这是我的代码，当有任何消息出现时，我的BroadCastReceiver会调用。从那开始我开始服务从收件箱中获取未读消息以及我将作为消息发送的消息。
我收到了来自收件箱的邮件但是当我将这些邮件作为邮件发送时，我得到了＃34; Nullpointer异常＆＃34;。
请有人告诉我我错在哪里吗？
修改
我发现当我在消息中发送文本长度时，它会给我NullPointer异常。当我在谷歌上搜索时，我发现通过使用 sendMultipartTextMessage 安装使用 sendTextMessage 来解决问题。但是我已经使用了那种方法，为什么我会收到这个错误？
感谢。
答案 0 :(得分：2)
你好，我得到了solution。我很高兴与你们分享。我用了
ArrayList messages = sms.divideMessage（message）;
SmsManager sms = SmsManager.getDefault();
ArrayList<String> messages = sms.divideMessage(message);
sms.sendMultipartTextMessage(destNumber, null, messages, ayySentPI, ayyDeliveredPI);
