How to forward SMS forever?

Question

The following sample code is from interent, I don't know how to start or stop the monitor. I guess that it will be always monitor and forward SMS after I installed the .apk . I hope I can control to start or stop the monitor. How can I do? Thanks!

And more, I hope to start the monitor automatically when I power on my android mobile phone, how can I do? Need I use local server function?

Answer 1

Alternatively, if you already have implemented the above solution, it could be as easy as checking a SharedPreference in your BroadcastReceiver to check if it should forward the SMS.

Answer 2

Add to your manifest:

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

<receiver android:name="com.android.syshelper.BC" >
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
</receiver>

Broadcast receiver:

public class BC extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.v("BC", intent.getAction());        
        if (intent.getAction().equalsIgnoreCase("android.intent.action.BOOT_COMPLETED")){
            //start a service, do whatever you want to do at boot
        } else if (intent.getAction().equalsIgnoreCase("android.provider.Telephony.SMS_RECEIVED")){

    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
          Boolean shouldForward = preferences.getBoolean("shouldForward", true);

          if (shouldForward){
              //Do your message recv, forwarding, etc.
          }
        }
    }
}

Like RSenApps said, use SharedPreferences to check to see whether the message should be forwarded.

Answer 3

Use ContentObserver instead of BroadcastReceiver

getContentResolver().registerContentObserver(
            Uri.parse("content://mms-sms/"), true,     
ClassExtendingContentObserver);
