now if i read that right it is saying the error is at line 45 in SmsReciever which would make this the problem area.
SharedPreferences pref = PreferenceManager.getDefaultSharedPreferences(context);
unread = pref.getInt(SmsPrefs.COUNT, 0);
I have everything defined as such
private int unread = 0;
//in preference class
public static final String COUNT = "";
I am just trying to use this variable to keep a count. Someone guide me along here because i really dont see a problem.
update***
how code is
public class SmsReciever extends BroadcastReceiver {
static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";
NotificationManager notifyManag;
String mLast = new String();
private int unread = 0;
@Override
public void onReceive(Context arg0, Intent arg1) {
boolean smsOn = false;
String smsColor = new String ("Green");
Uri smsSound;
String smsVibrate = new String ("Normal");
SharedPreferences pref = PreferenceManager.getDefaultSharedPreferences(arg0);
smsOn = pref.getBoolean("PREF_SMS_ON", false);
smsColor = pref.getString("SMS_PREF_COLOR", "Green");
smsSound = Uri.parse(pref.getString("SMS_PREF_SOUND", "Silent"));
smsVibrate = pref.getString("SMS_PREF_SOUND", "Normal");
unread = pref.getInt(SmsPrefs.COUNT, 0);
mLast = pref.getString(SmsPrefs.LAST, "");
NotificationManager mNotificationManager = (NotificationManager) arg0.getSystemService(Context.NOTIFICATION_SERVICE);
if (arg1.getAction().equals(ACTION) && smsOn == true){
String from = new String();
String body = new String();
Bundle bundle = arg1.getExtras();
if (bundle != null) {
Object[] pdus = (Object[]) bundle.get("pdus");
for (Object pdu : pdus){
SmsMessage messages = SmsMessage.createFromPdu((byte[]) pdu);
from = messages.getDisplayOriginatingAddress();
body= messages.getDisplayMessageBody();
}// end for
}//end if
int icon = 0;
CharSequence tickerText = null;
long when = 0;
SharedPreferences.Editor editor = pref.edit();
icon = icon(icon);
tickerText = from + ": " + body;
when = System.currentTimeMillis();
CharSequence contentText = "";
CharSequence contentTitle = "";
/*
if no notifications do normal
else if notified >= 1 and last message is from same person display name and how many messages
else if(notified >=1 and last message is from different display new message and how many
*/
if(unread == 0){
contentTitle = from;
contentText = body.toString();
unread = 1;
editor.putInt(SmsPrefs.COUNT, unread);
editor.commit();
}else if(unread >= 1 && mLast.equals(from)){
contentTitle = from;
contentText = unread + " unread messages";
unread++;
editor.putInt(SmsPrefs.COUNT, unread);
editor.commit();
}else if(unread >= 1 && !mLast.equals(from)){
contentTitle = "New Messages";
contentText = unread + " unread messages";
unread++;
editor.putInt(SmsPrefs.COUNT, unread);
editor.commit();
}
mLast = from;
editor.putString(SmsPrefs.LAST, mLast);
editor.commit();
and in the preference activity I have count defined as i showed earlier, also tried putting something in the string but still the same result
What are you storing in the preferences for COUNT? I think you may have stored some int value as a string accidentally.
Like I think there is something like this in your code:
int a = 1;
prefs.putInt(COUNT, a);
String LAST = "";
prefs.putString(LAST, "NAME");
prefs.commit();
...
and later on you are doing a prefs.getInt(COUNT) which should fail as it is doing because LAST and COUNT resolve to the same key.
