Question

我的应用程序将SMS从一个设备发送到另一个设备。

问题是当关闭接收设备时，我仍然会收到OK通知意图。

这是我真正交付短信（第1行）时所得到的，以及由于第二台设备关闭而未送达的时间：

delivered: intent=Intent { act=SMS_DELIVERED flg=0x10 (has extras) } extras=Bundle{ pdu => [B@41a7a850; format => 3gpp; }Bundle
delivered: intent=Intent { act=SMS_DELIVERED flg=0x10 (has extras) } extras=Bundle{ pdu => [B@41719ae8; format => 3gpp; }Bundle

是否有便携式（不依赖于提供商）的方式来确定SMS是否已经交付？

Answer 1

函数SmsMessage.getStatus()给出状态代码。状态码0表示成功（嗯，仅适用于GSM）;非零状态代码取决于它是CDMA消息还是GSM消息。

所以：

int status = -1;
byte[] pdu = intent.getByteArrayExtra("pdu");
if (pdu != null) {
    SmsMessage sms = SmsMessage.createFromPdu(pdu);
    status =  sms.getStatus();
}

相应地，当接收设备关闭时，我会进入日志：

status = 0x30
status = 0x0

但并非所有： C.S0015-B，v2.0,4.5.21 （link）（对于CDMA）读取（请注意，Android会将这些转换为值为16位，并将状态字节分成两个status = mBearerData.errorClass << 8; status |= mBearerData.messageStatus;}：

Status
Code     Message Status 
ERROR_CLASS = ‘00’ (no error) 
‘000000’ Message accepted 
‘000001’ Message deposited to Internet 
‘000010’ Message delivered 
‘000011’ Message cancelled 

ERROR_CLASS = ‘10’ (temporary condition) 
‘000100’ Network congestion 
‘000101’ Network error 
‘011111’ Unknown error 

ERROR_CLASS = ‘11’ (permanent condition) 
‘000100’ Network congestion 
‘000101’ Network error 
‘000110’ Cancel failed 
‘000111’ Blocked destination 
‘001000’ Text too long 
‘001001’ Duplicate message 
‘001010’ Invalid destination 
‘001101’ Message expired 
‘011111’ Unknown error 
All other values reserved.

和 TS 23.040,9.2.3.15 TP-Status （link）（对于GSM）读取：

1110000..1111111 Values specific to each SC

仅检查0是不正确的，因为状态代码可能恰好是2，实际上，CDMA＆＃34;消息已经传送到＃34;代码是2而不是0！重要的是知道是否会进行更多尝试，即检查5-6或4-5位（甚至消息类位组合具有不同的含义！）我的日志中的值0x30以上是指0110000＆＃34;特定于服务中心的价值＆＃34; 0x0表示＆＃34;中小企业收到的短信＆＃34;其中SME（短消息实体）是任何支持SMS的东西，也就是这种情况下的接收设备。

现在，您必须intent.getStringExtra("format")，具体取决于"3gpp"或"3gpp2"解码状态代码。

如果有人可以在GSM和CDMA网络下编写代码和进行测试，请发布经过测试的代码！
