All queries in RoomDatabase return: The columns returned by the query does not have the fields

I have a problem with queries in RoomDatabase. I have a different queries and everything works good when I use SELECT statement with *. When I want to choose only name_product or amount it gives an error:
error: The columns returned by the query does not have the fields [id,amount,to_shop,cat_food,cat_package] in com.example.myapp.PojoClass even though they are annotated as non-null or primitive. Columns returned by the query: [name_product,amount]
LiveData<List<Items>> getItemNameAndAmount(int category);
One of my query:
#Query("SELECT name_product, amount FROM Table WHERE to_shop = 1 AND food_type = :category")
LiveData<List<Item_get>> getCategoryThingsToBuy(int category);
Problem is similar with this:
Android Room error: The columns returned by the query does not have the fields even though they are annotated as non-null or primitive
But I don't understand why this won't compile. Can somebody tell me?
In my PojoClass I have got a lot of different fields but only categories above are return as an error.
Why Android Studio doesn't throw me all of my Pojo fields as error? Not Only those above.
It throws errors in all queries statements not in one or two.
If it matter I have a empty constructor in my PojoClass.
EDIT:

How to get optimized java code from kotlin source file?

I have converted below kotlin file from existing options

It is seems to be buggy. very difficult to understand.is there any options to get pure java code ? please let me know if we can able to perform conversion other than android studio

You have to realise that kotlin runs on JVM, hence it can do everything that Java can and nothing more. The extra features that Kotlin provides such as not null types etc are implemented using same byte code that java uses.
All the extra java code that you call "buggy", is there for some specific feature requirement of kotlin.
For example all the Intrinsics.checkParameterIsNotNull checks are there on variables that are declared non nullable, that is how kotlin makes sure that nulls are not introduced in such variables.
So the java output you see doesn't contain any extra code, its the actual java equivalent code of your kotlin class.

android, Comparator sort wrong

I have a Comparator to sort by 3 values:
ORDER_BY_Points
ORDER_BY_Gdif // goals difference
ORDER_BY_Goals
First I get a array from a json string. I send the array to StandingsSort.ORDER_BY_RULES
Arrays.sort(addressArray, StandingsSort.ORDER_BY_RULES);
Here is my code:
static final Comparator<Standings> ORDER_BY_Points = new Comparator<Standings>() {
public int compare(Standings a1, Standings a2) {
return a1.points.compareTo(a2.points);
}
};
static final Comparator<Standings> ORDER_BY_Gdif = new Comparator<Standings>() {
public int compare(Standings a1, Standings a2) {
return a1.Gdif.compareTo(a2.Gdif);
}
};
static final Comparator<Standings> ORDER_BY_Goals = new Comparator<Standings>() {
public int compare(Standings a1, Standings a2) {
return a1.goalsP.compareTo(a2.goalsP);
}
};
static final Comparator<Standings> ORDER_BY_RULES = new Comparator<Standings>() {
public int compare(Standings a1, Standings a2) {
int i = ORDER_BY_Points.compare(a1,a2);
if(i == 0){
i = ORDER_BY_Gdif.compare(a1,a2);
if(i == 0){
i = ORDER_BY_Goals.compare(a1,a2);
}
}
return i;
}
};
class Standings {
String teamName;
String goalsP;
String goalsM;
String Gdif;
String points;
#Override
public String toString() {
return "" + teamName + "," + goalsP + ":" + goalsM + "," + Gdif + "," + points + "";
}
public Standings(String teamName, String goalsP,
String goalsM, String Gdif, String points) {
super();
this.teamName = teamName;
this.goalsP = goalsP;
this.goalsM = goalsM;
this.Gdif = Gdif;
this.points = points;
}
}
But the result is not OK! Here is the result
Name, Goals, GDif, Points
Team,11:9,2,10
Team,5:3,2,10
Team,9:2,7,11
Team,0:6,-6,2
Team,3:9,-6,2
Team,6:9,-3,3
Team,8:13,-5,3
Team,8:9,-1,5
Team,8:11,-3,5
Team,8:7,1,5
Why does the Comparator sort wrong?

Since you store the points as Strings, "10" comes before "2", "3", and "5". If you want to compare these in order by the numerical value, you need to convert them into ints first.
Similarly, Gdif and Goals are compared as Strings which is probably not what you want.

Display list of time zones similar to that of timezones displayed in S Planner app

Is there a way in which I can display the list of Time zones in a format like (GMT+1.00) Windhoek like the way we see in S Planner on the Android app?
Can anyone help me in sorting out this issue?
Thanks in adavance

First I suggest you to create a wrapper class to manage the format of TimeZone objects as follow:
public class TimeZoneWrapper {
private final TimeZone timeZone;
private String timeZoneID;
private String timeZoneDisplay;
private String timeZoneRawDisplayName;
public TimeZoneWrapper(final TimeZone timeZone) {
this.timeZone = timeZone;
setDisplayStrings();
}
private void setDisplayStrings() {
this.timeZoneID = timeZone.getID().replaceAll("_", " ");
int offset = timeZone.getRawOffset();
if (timeZone.inDaylightTime(new Date())) {
offset = offset + timeZone.getDSTSavings();
}
this.timeZoneRawDisplayName = timeZone.getDisplayName(false,
TimeZone.SHORT);
final int offsetHrs = offset / 1000 / 60 / 60;
final int offsetMins = offset / 1000 / 60 % 60;
if (offsetHrs + offsetMins == 0) {
this.timeZoneDisplay = "GMT";
} else {
String suffix = "";
if (offset < 0) {
suffix += "-";
} else {
suffix += "+";
}
if (offsetMins != 0) {
suffix += offsetHrs + "." + offsetMins;
} else {
suffix += offsetHrs;
}
this.timeZoneDisplay = "GMT" + suffix;
}
}
public String getTimeZoneID() {
return timeZoneID;
}
public String getTimeZoneDisplay() {
return timeZoneDisplay;
}
public String getTimeZoneRawDisplayName() {
return timeZoneRawDisplayName;
}
public TimeZone getTimeZone() {
return timeZone;
}
#Override
public final boolean equals(final Object o) {
if (this == o) {
return true;
}
if (!(o instanceof TimeZoneWrapper)) {
return false;
}
final TimeZoneWrapper that = (TimeZoneWrapper) o;
return that.timeZone.equals(this.timeZone);
}
}
Once you have created (if you want) this wrapper class you can retrieve the TimeZones from your device with the following method in your mainActivity.
private List<TimeZoneWrapper> buildTimeZoneWrappers() {
final List<TimeZoneWrapper> timeZoneWrappers = new ArrayList<TimeZoneWrapper>();
final List<TimeZone> timeZones = new ArrayList<TimeZone>();
final String[] timeZoneIds = TimeZone.getAvailableIDs();
for (final String id : timeZoneIds) {
timeZones.add(TimeZone.getTimeZone(id));
}
for (final TimeZone timeZone : timeZones) {
timeZoneWrappers.add(new TimeZoneWrapper(timeZone));
}
return timeZoneWrappers;
}
Now you have a list of "well" formatted timezone, so if you need a picker with this value you simply have to create one with them.
String[] temp;
for (int i=0;i<timeZoneWrappers.size();i++){
temp[i]=timeZoneWrappers.get(i).getTimeZoneDisplay();
}
NumberPicker picker = new NumberPicker(getApplicationContext());
picker.setDisplayedValues(temp);
Let me know;)

How can I parse price from Google Play In-app Billing

I use the follow code to parse price from Google Play In-app Billing:
private static Number parsePrice(String priceFromGoogle) {
Locale currencyLocale = getCurrencyLocale(priceFromGoogle);
NumberFormat numberFormat = NumberFormat.getCurrencyInstance(currencyLocale);
Number number = null;
try {
number = numberFormat.parse(priceFromGoogle);
} catch (ParseException e) {
e.printStackTrace();
}
return number;
}
private Locale getCurrencyLocale(String price) {
Locale locale = null;
for (Locale availableLocale : Locale.getAvailableLocales()) {
NumberFormat numberFormat = NumberFormat.getCurrencyInstance(availableLocale);
try {
numberFormat.parse(price);
locale = availableLocale;
break;
} catch (ParseException e) {
//do nothing
}
}
return locale;
}
It works fine on my test devices and in my locale. But on some devices and in some countries I encounter prices like this: "Php1,337.07", "US$ 29.99", "MX$374.79". My approach doesn't work in this case.
Is there an universal approach to solve this problem?

Check their In-app billing sample project and modify SkuDetails.java so that you can get that information as well:
import org.json.JSONException;
import org.json.JSONObject;
/**
* Represents an in-app product's listing details.
*/
public class SkuDetails {
String mItemType;
String mSku;
String mType;
int mPriceAmountMicros;
String mPriceCurrencyCode;
String mPrice;
String mTitle;
String mDescription;
String mJson;
public SkuDetails(String jsonSkuDetails) throws JSONException {
this(IabHelper.ITEM_TYPE_INAPP, jsonSkuDetails);
}
public SkuDetails(String itemType, String jsonSkuDetails) throws JSONException {
mItemType = itemType;
mJson = jsonSkuDetails;
JSONObject o = new JSONObject(mJson);
mSku = o.optString("productId");
mType = o.optString("type");
mPrice = o.optString("price");
mPriceAmountMicros = o.optInt("price_amount_micros");
mPriceCurrencyCode = o.optString("price_currency_code");
mTitle = o.optString("title");
mDescription = o.optString("description");
}
public String getSku() { return mSku; }
public String getType() { return mType; }
public String getPrice() { return mPrice; }
public String getTitle() { return mTitle; }
public String getDescription() { return mDescription; }
public int getPriceAmountMicros() { return mPriceAmountMicros; }
public String getPriceCurrencyCode() { return mPriceCurrencyCode; }
#Override
public String toString() {
return "SkuDetails:" + mJson;
}
}

You can get the price in micros in the JSON retrieved by IabHelper.
This is not officially documented but here is how I've done it by editing SkuDetails.java :
public class SkuDetails {

Hope this helps !
PS : I tried your Price class but it parsed 0.8 for 0,89 €

As Google Play may return prices in currency format which is unsupported by java.text.NumberFormat, I wrote my own implementation
public class Price {
private double value;
private String currency;
private String pattern;
private DecimalFormat decimalFormat;
private Price() {}
private static String currencyToDecimalFormat(String value, Price price) {
char decimalSeparator = '.';
char groupingSeparator = 0;
if (value.length() >= 3) {
char[] chars = value.toCharArray();
if (chars[chars.length - 2] == ',') {
decimalSeparator = ',';
chars[chars.length - 2] = '.';
} else if (chars[chars.length - 3] == ',') {
decimalSeparator = ',';
chars[chars.length - 3] = '.';
}
value = new String(chars);
}
if (value.contains(",")) {
groupingSeparator = ',';
value = value.replaceAll(",", "");
} else if (value.contains(" ")) {
groupingSeparator = ' ';
value = value.replaceAll(" ", "");
} else if (value.contains("\u00A0")) {
groupingSeparator = '\u00A0';
value = value.replaceAll("\u00A0", "");
}
DecimalFormatSymbols symbols = new DecimalFormatSymbols();
if (groupingSeparator != 0) {
price.decimalFormat = new DecimalFormat("###,###.00");
symbols.setGroupingSeparator(groupingSeparator);
} else {
price.decimalFormat = new DecimalFormat("######.00");
}
symbols.setDecimalSeparator(decimalSeparator);
price.decimalFormat.setDecimalFormatSymbols(symbols);
return value.replaceAll(",", "");
}
public static Price parsePrice(String priceFromGoogle) {
Price price = new Price();
StringBuilder patternBuilder = new StringBuilder();
Pattern pattern = Pattern.compile("(?:[0-9]{1,3})(?:[0-9,.\\s\u00A0]+)");
Matcher matcher = pattern.matcher(priceFromGoogle);
matcher.find();
String priceString = matcher.group();
if (priceFromGoogle.indexOf(priceString) == 0) {
if (priceFromGoogle.length() != priceString.length()) {
price.currency = priceFromGoogle.substring(priceString.length());
} else {
price.currency = "";
}
} else {
price.currency = priceFromGoogle.substring(0, priceFromGoogle.indexOf(priceString));
}
price.currency = price.currency.trim();
if (priceFromGoogle.startsWith(price.currency)) {
patternBuilder.append("%1s");
char nextChar = priceFromGoogle.charAt(price.currency.length());
if (nextChar == ' ' || nextChar == 0xA0) {
patternBuilder.append(' ');
}
patternBuilder.append("%2$s");
} else {
patternBuilder.append("%2$s");
char prevChar = priceFromGoogle.charAt(priceFromGoogle.indexOf(price.currency) - 1);
if (prevChar == ' ' || prevChar == 0xA0) {
patternBuilder.append(' ');
}
patternBuilder.append("%1s");
}
price.pattern = patternBuilder.toString();
priceString = trim(priceString);
priceString = currencyToDecimalFormat(priceString, price);
price.value = Double.parseDouble(priceString);
return price;
}
#Override
public String toString() {
if (pattern != null) {
return String.format(pattern, currency, decimalFormat.format(value));
} else {
return "";
}
}
}
EDIT1:
Because of Google uses non-breaking space instead of usual space you need check this and use custom trim function:
public static String trim(String text) {
int start = 0, last = text.length() - 1;
int end = last;
while ((start <= end) && (text.charAt(start) <= ' ' || text.charAt(start) == 0xA0)) {
start++;
}
while ((end >= start) && (text.charAt(end) <= ' ' || text.charAt(end) == 0xA0)) {
end--;
}
if (start == 0 && end == last) {
return text;
}
return text.substring(start, end);
}
