We Keep Coding

I don't understand this error message, any help would be helpful

I tried to build my app, and this error message was produced.
Unexpected character '=' (code 61) (expected a name start character)
at [row,col {unknown-source}]: [41,21]
I have cleaned my code and tried to clean my code and inspected my code and i can't find anything wrong my code, and help would be gratefully recieved.
This is my MainActivity.

Cant find a way to delete an item from sharedPreferences

I am trying to delete an item from taskList which is connected to sharedPreferences.
I managed to remove all items but the problem is I cant find a way to connect a counter to delete an individual item from a list that has a switch and when this switch is on true I need to remove the item from list by index number.
public class TaskAdapter extends BaseAdapter {
//transfer context

//transfer user to use for shared preferences

Sorry for the long code but I have spent so much time on that problem and didnt find a normal way to fix it...
Thanks in advance guys, much appreciated!

taskEditor.remove('item tag');
taskEditor.commit();

Guess my question wasnt clear enough but I have found a way to do that.
if(!taskDone){
String myData = taskName+","+taskInfo+","+(taskDone?"1":"0");
taskEditor.putString(taskName,myData);
//apply the changes
taskEditor.commit();
}
else
{
taskEditor.remove(taskName);
taskEditor.commit();
adapter.notifyDataSetChanged();
}
Eventhough its not perfect because I can refresh the view after I update the Editor and only after I restart the app my last deleted tasks disappear.
Cheers and thanks a lot guys!

This will be the best approach for your Solution,Try using Universal Image Loader.
Features:
Multithread image loading (async or sync)
Wide customization of ImageLoader's configuration (thread executors, downloader, decoder, memory and disk cache, display image options, etc.)
Many customization options for every display image call (stub images, caching switch, decoding options, Bitmap processing and displaying, etc.)
Image caching in memory and/or on disk (device's file system or SD card)
Listening loading process (including downloading progress)

TimePicker Saves Zero Value in SQLite Database

I have a TimePicker which I'd like to use to determine a length of time a user can stay connected. Lets say the time now is 10:00 if the user selects 11:00 - I'd like the source code below to determine that there are 60 minutes between the current time - and the time selected and set that to a string/long (minutes) which I then have displayed as a textview.
I've coded everything as I thought it should be - however the textview never seems to update with minutes value. Everytime I attempt to view the data - I get a value of 0 not matter what the timepicker is set to.
Anyone have any suggestions? I'm stumped at the moment and I'm not sure what else to try.

You have that code to add a contact, BUT in your database conector you have:
public void insertContact(String name,
String cap,
String code,
String time,
long minutes,
String ssid,
String string){
I think that don't match, so this is why don't insert correctly.
BTW i can't comment at the moment because i need 50 reputation.

USE CREATE TABLE IF NOT EXISTS T/N then your problem wil be solved.
otherwise it will override the current table at the same time all the data will be lost.

How to hide two wrong answers in a quiz?

Like in "Who wants to be a millionaire". When a user press a 50/50 help button I want two wrong answers to hide, therefor to setText to "" for two buttons, BUT not "the answer" one.

OK, as jazzbassrob pointed I need to be more specific. I need to setText to my bPolaPola button to "", empty String, but my main problem is that I don't know after collections shuffle where my answers will end up, so I don't know which buttons to setText to. How to know where my answers end up after shuffle?
I actually did not try anything cause in this specific situation I really don't know where to start.

How about running a query which will find the correct option even before the user clicks on one, then you find the correct button out of the four options. After this, use setText="" on any random two buttons other than the one which points to the correct answer.
