先生
我是Android上的新手，现在在发送和接收短信方面遇到问题.实际上，我在项目名称ZigbeeActivity，SettingActivity，OnOffActivity等中分别有5个Activity类，现在我想发送一个SMS，这是一个单独的类SendSMS和SMSReceiver类从SettingActivit编写并调用一个函数到SendSMSclass的SMSsend，但是在发送致命异常时会在Settingctiviy屏幕上显示.我将SendSMS类的源代码绑定在pl下方.帮帮我.

    }
    }

推荐答案

您有一个

@SuppressWarnings("unused")

在其中-因此我假设该函数从未使用过，并且您不会在IDE中看到该消息，因为由于此注释而未显示警告，但是当您删除它时，您会发现有问题，然后您会发现FatalException弹出的位置. * takeAdeepBreath(); *

You have an

@SuppressWarnings("unused")

in there - so I assume the function is never used and you do not see that in the IDE as the warning doesn''t show up due to this annotation but when you would delete that you would find out that there is something wrong and then you would find out where the FatalException pops. *takeAdeepBreath();*
