Question

我想阅读传入的短信..我创建了这个类来做到这一点：

public class smsRec extends BroadcastReceiver {
    private static final String LOG_TAG = "SMSApp";

    /* package */ static final String ACTION =
            "android.provider.Telephony.SMS_RECEIVED";

    // @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(ACTION)) {
            // if(message starts with SMStretcher recognize BYTE)
            StringBuilder sb = new StringBuilder();

            /* The SMS-Messages are 'hiding' within the extras of the Intent. */
            Bundle bundle = intent.getExtras();
            if (bundle != null) {
                /* Get all messages contained in the Intent*/
                android.telephony.SmsMessage[] messages = 
                    Telephony.Sms.Intents.getMessagesFromIntent(intent);

                /* Feed the StringBuilder with all Messages found. */
                for (android.telephony.SmsMessage currentMessage : messages){
                    sb.append("Received compressed SMSnFrom: ");
                    /* Sender-Number */
                    sb.append(currentMessage.getDisplayOriginatingAddress());
                    sb.append("n----Message----n");
                    /* Actual Message-Content */
                    sb.append(currentMessage.getDisplayMessageBody());
                }
            }
            /* Logger Debug-Output */
            Log.i(LOG_TAG, "[SMSApp] onReceiveIntent: " + sb);

            /* Show the Notification containing the Message. */ 
            Toast.makeText(context, sb.toString(), Toast.LENGTH_LONG).show();

        }
    }

    private void appendData(StringBuilder buf, String key, String value) {
        buf.append(", ");
        buf.append(key);
        buf.append('=');
        buf.append(value);
    }


}

并在清单中：

<receiver android:name=".SMSReceiver">
            <intent-filter>
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>

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

但我得到一个错误，logcat是：

我无法找到问题

Answer 1

java和manifest中的类名必须匹配。现在一个叫做SMSReceiver，另一个是smsRec

Android接收器短信不起作用
