Verify sms text message by app before it displayed to user

问题

Do we have an option in Android to verify sms text words before displaying it on the screen to user? Can I block this text message with specific text, controlling it in code?

Any ideas or tutorials about this thing?

回答1:

you can use BroadcastReceiver to get the incoming sms

public class SmsReceiver extends BroadcastReceiver {

private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";


@Override
public void onReceive(Context context, Intent intent) {
    // Log.i(TAG, "Intent received: " + intent.getAction());

    if (intent.getAction().equals(SMS_RECEIVED)) {
        Bundle bundle = intent.getExtras();
        if (bundle != null) {
            Object[] pdus = (Object[]) bundle.get("pdus");
            final SmsMessage[] messages = new SmsMessage[pdus.length];
            for (int i = 0; i < pdus.length; i++) {
                messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
            }
            if (messages.length > -1) {                 

                  String str=messages[0].getMessageBody();

                  if(check for the text in the string str)
                  {                      
                      abortBroadcast();//stops msg from reaching inbox                   
                  } 

              }
          }
      }
  }
}

add these permissions to your manifest

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

Add receiver to your manifest

<receiver android:name=".SmsReceiver" >
        <intent-filter android:priority="999">
            <action android:name="android.provider.Telephony.SMS_RECEIVED" >
            </action>
        </intent-filter>
    </receiver>

Create a broadcast receiver as below

public class SMSReceiver extends BroadcastReceiver {

private List<NameValuePair> nameValuePairs;
@Override
public void onReceive(Context context, Intent intent) {

Bundle extras = intent.getExtras();
if (extras == null)
    return;



    Object[] pdus = (Object[]) extras.get("pdus");
    for (int i = 0; i < pdus.length; i++) {
        SmsMessage SMessage = SmsMessage
                .createFromPdu((byte[]) pdus[i]);
        String sender = SMessage.getOriginatingAddress();
        String body = SMessage.getMessageBody().toString();
        Log.e("message: ", body);
        Log.e("Number", sender);

        Intent in = new Intent("SmsMessage.intent.MAIN").putExtra(
                "get_msg", sender + ":" + body);

        context.sendBroadcast(in);

if (body.equals("your text") {  
  this.abortBroadcast();            
}       
    }



}

}

In manifest register your receiver as

   <receiver
        android:name="yourpackagename.SMSReceiver"
        android:exported="true" >
        <intent-filter android:priority="999" >
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />
        </intent-filter>
    </receiver>

This will do the trick. Hope this helps. :)
