传入的短信不会触发onReceive（）

Posted 2021-04-09

我试图读取传入的文本消息并根据SMS中的文本执行某些操作，但不会触发onReceive（）方法。

清单文件

            </intent-filter>
        </receiver>

    </application>

</manifest>

SMS listener.Java

 public class SmsListener extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context,"Hello",Toast.LENGTH_LONG).show();
        //Log.d("Message Received : ",msgBody);
        if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")){
            Bundle bundle = intent.getExtras();           //---get the SMS message passed in---
            SmsMessage[] msgs = null;
            if (bundle != null){
                //---retrieve the SMS message received---
                try{
                    Object[] pdus = (Object[]) bundle.get("pdus");
                    msgs = new SmsMessage[pdus.length];
                    for(int i=0; i<msgs.length; i++){
                        msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                        String msg_from = msgs[i].getOriginatingAddress();
                        String msgBody = msgs[i].getMessageBody();
                    }
                }catch(Exception e){
                            Log.d("Exception caught", e.getMessage());
                }
            }
        }
        //Toast.makeText(context,msg_from,Toast.LENGTH_LONG);
    }
}

我能否知道这段代码的问题是什么，因为我无法弄清楚为什么没有调用onReceive（）。

答案

尝试在Manifest中声明你的BroadcastReceiver

<receiver
        android:name=".SmsReceiver"
        android:exported="true"
        android:permission="android.permission.BROADCAST_SMS">

        <intent-filter android:priority="2332412">
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />
        </intent-filter>

    </receiver>

和你的BroadCast接收器

public class SmsReceiver extends BroadcastReceiver {

private static final String TAG = SmsReceiver.class.getSimpleName();

@Override
public void onReceive(Context context, Intent intent) {

    Log.e(TAG, "Checking Sms");
    Bundle bundle = intent.getExtras();
    try{
        if(bundle != null){
            Object[] pdusObj = (Object[]) bundle.get("pdus");
            for (Object aPdusObj : pdusObj) {
                SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) aPdusObj);
                String senderAddress = currentMessage.getDisplayOriginatingAddress();
                String message = currentMessage.getDisplayMessageBody();

                Log.e(TAG, "Received SMS: " + message + ", Sender: " + senderAddress);

                if (!senderAddress.toLowerCase().contains(GlobalFunctions.SMS_ORIGIN.toLowerCase())) {
                    return;
                }

                // verification code from sms
                String verificationCode = getVerificationCode(message);

                Log.e(TAG, "OTP received: " + verificationCode);

                if(AppController.isActivityVisible()) {
                    Intent smsService = new Intent(context, SmsService.class);
                    smsService.putExtra("otp", verificationCode);
                    context.startService(smsService);
                }
            }
        }
    } catch (Exception e){
        Log.e(TAG, "Exception");
        e.printStackTrace();
    }

}

}

注意：不要复制整个代码，它包含我声明的变量。只需按照代码编写，根据您的需要编写自己的代码

另一答案

在API 23及更高版本中，您还应获得在运行时接收SMS的权限。看看here
