即使應用程序收到短信，我的onReceive（）也不會被調用。它在消息到達時不會被調用。它不應該在後臺工作，只有在SMS到達時纔會被調用？ 它可以在單獨的項目上正常工作，但不會在我與我的應用程序進行交互時運行。廣播接收器不能正常工作，onReceive（）不會被調用。我應該如何解決它？
我的代碼：
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;
public class SmsBroadcastReciever extends BroadcastReceiver {
private static final String LOG_TAG = "SMSBroadRec";
public static final String SMS_BUNDLE = "pdus";
String SenderNo = "+92----------";
String SenderNo2 = "+92----------";
@Override
public void onReceive(Context context, Intent intent) {
Log.d(LOG_TAG, "In onReceive()");
Bundle bundle = intent.getExtras();
String smsBody;
String address;
try {
if (!bundle.isEmpty()){
Log.d(LOG_TAG, "Sms received");
String verificationCode = null;
Object[] sms = (Object[]) bundle.get(SMS_BUNDLE);
for (Object sm : sms) {
SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) sm);
smsBody = smsMessage.getMessageBody();
address = smsMessage.getOriginatingAddress();
Log.d(LOG_TAG, address);
if (SenderNo.equals(address) || SenderNo2.equals(address)) {
verificationCode = getVerificationCode(smsBody);
Log.e(LOG_TAG, "OTP received: " + verificationCode);
break;
} else {
Log.d(LOG_TAG, "wrong sender");
break;
}
}
SharedPreferences prefs = context.getSharedPreferences(AppConfig.APP_SCRATCH, Context.MODE_PRIVATE);
SharedPreferences.Editor ed = prefs.edit();
ed.putString(AppConfig.APP_SCRATCH, verificationCode);
if (ed.commit()) {
Log.d(LOG_TAG, "commit succesful"); //added to the shared preferences
} else {
Log.d(LOG_TAG, "commit unsuccessful");
}
} else {
Log.d(LOG_TAG, "Intent must be empty!");
}
}
catch (Exception e){
e.printStackTrace();
}
}
private String getVerificationCode(String message) {
String code = null;
int index = message.indexOf(AppConfig.OTP_DELIMITER);
if (index != -1) {
int start = index + 2;
int length = 8;
code = message.substring(start, start + length);
return code;
}
return code;
}
}
這是清單文件的一部分，我已經添加權限過於它們READ_SMS，RECEIVE_SMS，WRITE_SMS。

你是否在清單文件中添加了sms權限？ –
是......接收，讀取，甚至寫入 – ibraizQ9
哪個代碼行導致NullPointerException？ – Akexorcist
