Question

无法使用真实设备发送短信。没有错误消息。我允许清单文件中的权限并导入必要的类，但仍然无法弄清楚出了什么问题。任何帮助将不胜感激。

sendMessage(contact,message);

    private void sendMessage(String contact, String message)
{
    SmsManager smsManager = SmsManager.getDefault();

    try {
        smsManager.sendTextMessage(contact, null , message , null , null);
        Toast.makeText(getApplicationContext(), "SMS Sent.", Toast.LENGTH_LONG).show();

    } catch (Exception e)
    {

        Toast.makeText(getApplicationContext(), "SMS failed to send.", Toast.LENGTH_LONG).show();

    }

}

清单

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

Answer 1

使用此功能..

sendMySMS（personalPhone，消息）;

 private void sendMySMS(String personalPhone, String messege)
{
    SmsManager sms = SmsManager.getDefault();
    List<String> messages = sms.divideMessage(messege);
    for (String msg : messages)
    {
        PendingIntent sentIntent = PendingIntent.getBroadcast(getActivity(), 0, new Intent("SMS_SENT"), 0);
        PendingIntent deliveredIntent = PendingIntent.getBroadcast(getActivity(), 0, new Intent("SMS_DELIVERED"), 0);
        sms.sendTextMessage(personalPhone, null, msg, sentIntent, deliveredIntent);
    }
}

添加权限...

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

如果您使用的是Android 6.0（API 23）或更高版本的真实设备，则必须在运行时请求权限。

SEND_SMS权限被归类为危险权限。

因此，在运行短信发送逻辑之前，您必须询问用户是否允许发送消息。

要做到这一点，首先需要在您的活动中添加它

 if (ContextCompat.checkSelfPermission(this, Manifest.permission.SEND_SMS) != PackageManager.PERMISSION_GRANTED) {

        ActivityCompat.requestPermissions(
                thisActivity,
                new String[]{Manifest.permission.SEND_SMS},
                MY_PERMISSIONS_REQUEST_SEND_SMS); 
    }

然后，您将检查用户是否已授予添加此覆盖方法的权限

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_SEND_SMS: {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // PERMISSION GRANTED
                // Now you can send sms
            } else {
                // PERMISSION DENIED
                // You should disable send sms feature
            }
            return;
        }
    }
}
