我正在尝试从这样的交付广播接收器Intent中的 PDU 中找出接收短信的人的电话号码onReceive()

@Override
public void onReceive(Context context, Intent intent) {
    ThizLog.d(TAG, "Inside onReceive");
    Bundle bundle = intent.getExtras();
    Object[] messages = (Object[]) bundle.get("pdus");
    SmsMessage[] sms = new SmsMessage[messages.length];

    for (int n = 0; n < messages.length; n++) {
        sms[n] = SmsMessage.createFromPdu((byte[]) messages[n]);
    }
    for (SmsMessage msg : sms) {
        // Verify if the message came from our known sender
        ThizLog.d(TAG,"!!! " + msg.getOriginatingAddress());

    }
    switch (getResultCode()) {
        case Activity.RESULT_OK:
            // SMS delivered
            break;
        case Activity.RESULT_CANCELED:
            /*
            *  SMS not delivered, show SMS_NOT_DELIVERED_MESSAGE
            */
            Toast toast = Toast.makeText(context, SMS_NOT_DELIVERED_MESSAGE, Toast.LENGTH_LONG);
            // shows toast on left top corner increase the zero value to
            // slide it right and down
            //toast.setGravity(Gravity.TOP | Gravity.LEFT, 0, 0);
            toast.show();
            break;
    }
}

但这导致了以下错误

有可能，Android 的原生 SMS 应用程序可以做到这一点。

我认为您没有从收到的意图中正确获取 pdu。它将是额外键“pdu”下的单个 pdu，而不是数组。

尝试这个：

public void onReceive(Context context, Intent intent) {
    String pdu=intent.getStringExtra("pdu");

    ...
}
