在Android中发送短信

概述我使用以下代码将SMS发送到 Android手机.但是,如果我将 SMS发送到任何号码,它就不会被发送.可能是什么问题？ package SMSApp.com;import android.app.Activity;import android.app.PendingIntent;import android.content.BroadcastReceiver;import androi 我使用以下代码将SMS发送到 Android手机.但是,如果我将 SMS发送到任何号码,它就不会被发送.可能是什么问题？

解决方法 我真的不明白你为什么要嵌套sendSMS方法 – 代码对我有用.试试检查你是否得到了

<uses-permission androID:name="androID.permission.SEND_SMS"></uses-permission>

在您的文件中设置权限并尝试使用此代码：
