With same instance of 'interpreter' score is getting increased for same image until it reaches at some saturation.

Map.Entry<String, Float> label = sortedLabels.poll();
textToShow = String.format("\n%s: %4.2f", label.getKey(), label.getValue()) + textToShow;
}
return textToShow;
}
At the first time when application gets launched score the image classification is 0.06 and then again if we called classifyImage() on some event click score gets increased to 0.13 and with same process it keeps increasing until it reached to 0.86(saturation).
I am not sure why its happening but it happened for both type of TfLite models inceptionV3 and MobileNet.

The results are filtered by the applyFilter method. It is a simple low pass filter, so the scores gradually arrive at their medium-term average. Comment out the call to applyFilter and it should respond instantly, but maybe too jittery for some applications.

Comparison of app version

How to compare app version in android
I got latest version code and current version code , but the problem is
current version is 1.0
and latest version is 1.0.0
so how to compare that float value in android

I have written a small Android library for comparing version numbers: https://github.com/G00fY2/version-compare
What it basically does is this:
public int compareVersions(String versionA, String versionB) {
String[] versionTokensA = versionA.split("\\.");
String[] versionTokensB = versionB.split("\\.");
List<Integer> versionNumbersA = new ArrayList<>();
List<Integer> versionNumbersB = new ArrayList<>();
for (String versionToken : versionTokensA) {
versionNumbersA.add(Integer.parseInt(versionToken));
}
for (String versionToken : versionTokensB) {
versionNumbersB.add(Integer.parseInt(versionToken));
}
final int versionASize = versionNumbersA.size();
final int versionBSize = versionNumbersB.size();
int maxSize = Math.max(versionASize, versionBSize);
for (int i = 0; i < maxSize; i++) {
if ((i < versionASize ? versionNumbersA.get(i) : 0) > (i < versionBSize ? versionNumbersB.get(i) : 0)) {
return 1;
} else if ((i < versionASize ? versionNumbersA.get(i) : 0) < (i < versionBSize ? versionNumbersB.get(i) : 0)) {
return -1;
}
}
return 0;
}
This snippet doesn't offer any error checks or handling. Beside that my library also supports suffixes like "1.2-rc" > "1.2-beta".

I am a bit late to the party but I have a great solution for all of you!
1. Use this class:
public class VersionComparator implements Comparator {
public boolean equals(Object o1, Object o2) {
return compare(o1, o2) == 0;
}
public int compare(Object o1, Object o2) {
String version1 = (String) o1;
String version2 = (String) o2;
VersionTokenizer tokenizer1 = new VersionTokenizer(version1);
VersionTokenizer tokenizer2 = new VersionTokenizer(version2);
int number1, number2;
String suffix1, suffix2;
while (tokenizer1.MoveNext()) {
if (!tokenizer2.MoveNext()) {
do {
number1 = tokenizer1.getNumber();
suffix1 = tokenizer1.getSuffix();
if (number1 != 0 || suffix1.length() != 0) {
// Version one is longer than number two, and non-zero
return 1;
}
}
while (tokenizer1.MoveNext());
// Version one is longer than version two, but zero
return 0;
}
number1 = tokenizer1.getNumber();
suffix1 = tokenizer1.getSuffix();
number2 = tokenizer2.getNumber();
suffix2 = tokenizer2.getSuffix();
if (number1 < number2) {
// Number one is less than number two
return -1;
}
if (number1 > number2) {
// Number one is greater than number two
return 1;
}
boolean empty1 = suffix1.length() == 0;
boolean empty2 = suffix2.length() == 0;
if (empty1 && empty2) continue; // No suffixes
if (empty1) return 1; // First suffix is empty (1.2 > 1.2b)
if (empty2) return -1; // Second suffix is empty (1.2a < 1.2)
// Lexical comparison of suffixes
int result = suffix1.compareTo(suffix2);
if (result != 0) return result;
}
if (tokenizer2.MoveNext()) {
do {
number2 = tokenizer2.getNumber();
suffix2 = tokenizer2.getSuffix();
if (number2 != 0 || suffix2.length() != 0) {
// Version one is longer than version two, and non-zero
return -1;
}
}
while (tokenizer2.MoveNext());
// Version two is longer than version one, but zero
return 0;
}
return 0;
}
// VersionTokenizer.java
public static class VersionTokenizer {
private final String _versionString;
private final int _length;
private int _position;
private int _number;
private String _suffix;
private boolean _hasValue;
VersionTokenizer(String versionString) {
if (versionString == null)
throw new IllegalArgumentException("versionString is null");
_versionString = versionString;
_length = versionString.length();
}
public int getNumber() {
return _number;
}
String getSuffix() {
return _suffix;
}
public boolean hasValue() {
return _hasValue;
}
boolean MoveNext() {
_number = 0;
_suffix = "";
_hasValue = false;
// No more characters
if (_position >= _length)
return false;
_hasValue = true;
while (_position < _length) {
char c = _versionString.charAt(_position);
if (c < '0' || c > '9') break;
_number = _number * 10 + (c - '0');
_position++;
}
int suffixStart = _position;
while (_position < _length) {
char c = _versionString.charAt(_position);
if (c == '.') break;
_position++;
}
_suffix = _versionString.substring(suffixStart, _position);
if (_position < _length) _position++;
return true;
}
}
}
2. create this function
private fun isNewVersionAvailable(currentVersion: String, latestVersion: String): Boolean {
val versionComparator = VersionComparator()
val result: Int = versionComparator.compare(currentVersion, latestVersion)
var op = "=="
if (result < 0) op = "<"
if (result > 0) op = ">"
System.out.printf("%s %s %s\n", currentVersion, op, latestVersion)
return if (op == ">" || op == "==") {
false
} else op == "<"
}
3. and just call it by
e.g. isNewVersionAvailable("1.2.8","1.2.9") where 1.2.8 is your current version here and 1.2.9 is the latest version, which returns true!

Why overcomplicate this so much?
Just scale the major, minor, patch version and you have it covered:
fun getAppVersionFromString(version: String): Int { // "2.3.5"
val versions = version.split(".") // [2, 3, 5]
val major = versions[0].toIntOrDefault(0) * 10000 // 20000
val minor = versions[1].toIntOrDefault(0) * 1000 // 3000
val patch = versions[2].toIntOrDefault(0) * 100 // 500
return major + minor + patch // 2350
}
That way when you compare e.g 9.10.10 with 10.0.0 the second one is greater.

Use the following method to compare the versions number:
Convert float to String first.
public static int versionCompare(String str1, String str2) {
String[] vals1 = str1.split("\\.");
String[] vals2 = str2.split("\\.");
int i = 0;
// set index to first non-equal ordinal or length of shortest version string
while (i < vals1.length && i < vals2.length && vals1[i].equals(vals2[i])) {
i++;
}
// compare first non-equal ordinal number
if (i < vals1.length && i < vals2.length) {
int diff = Integer.valueOf(vals1[i]).compareTo(Integer.valueOf(vals2[i]));
return Integer.signum(diff);
}
// the strings are equal or one string is a substring of the other
// e.g. "1.2.3" = "1.2.3" or "1.2.3" < "1.2.3.4"
return Integer.signum(vals1.length - vals2.length);
}

Check textures overlapping

Hey i am writing a game when there are bunch of textures that changes locations, but i want to check that they are not drawing over other textures, i tried to write a code for checking it but its not working well.
Here is the code i tried:
circles.setPosition(new Vector2(r.nextInt(width-height/8*2)+height/8,
r.nextInt(height-height/8*2)+height/8),
i);
circl[i].set((float) (circles.getPosition(i).x+height/16),
(float) (circles.getPosition(i).y+height/16),
height/16);
while(isLaping = true){
System.out.println("in");
for(int y = 0; y < circlesArray.length-1; y++){
if(Intersector.overlaps(circl[y], circl[y+1])){
circles.setPosition(new Vector2(r.nextInt(width-height/8*2)+height/8,
r.nextInt(height-height/8*2)+height/8),
i);
circl[i].set((float) (circles.getPosition(i).x+height/16),
(float) (circles.getPosition(i).y+height/16),
height/16);
}else{
isLaping = false;
}
}
}
How to fix it?

this is confusing,
while(isLaping = true){
you mean it
while(isLaping == true){
or
while(isLaping){
while(isLaping=true); isLaping never is false at the moment evaluate while because asign true every time

I tried again to do so with your tip but the circle are getting crazy and changes places every second
this is the code i have been trying.
for(int i = 0;i<circlesArray.length;i++)
{
if(circlesArray[i]>200)
{
changePosition(i);
}
circlesArray[i]++;
}
private void changePosition(int i)
{
int s = 0;
circles.setPosition(new Vector2(r.nextInt(width-height/12*2)+height/8,r.nextInt(height-height/12*2)+height/12),i);
circl[i].set((float) (circles.getPosition(i).x+height/24),(float) (circles.getPosition(i).y+height/24),height/24);
while (lap == true)
{
circles.setPosition(new Vector2(r.nextInt(width-height/12*2)+height/8,r.nextInt(height-height/12*2)+height/12),i);
circl[i].set((float) (circles.getPosition(i).x+height/24),(float) (circles.getPosition(i).y+height/24),height/24);
for(int y= i+1;y<circlesArray.length;y++)
{
if(circl[i].overlaps(circl[y]))
{
circles.setPosition(new Vector2(r.nextInt(width-height/12*2)+height/8,r.nextInt(height-height/12*2)+height/12),i);
circl[i].set((float) (circles.getPosition(i).x+height/24),(float) (circles.getPosition(i).y+height/24),height/24);
s=0;
}
else
{
s++;
}
}
if(s == circlesArray.length)
lap = false;
}
circlesArray[i] = 0;
x[i] = r.nextInt(circleTexture.length);
}

LUHN credit-card validation fails on a valid card number

In my application i want to check whether the user have entered valid card number for that i have used LUHN algorithm.I have created it as method and called in the mainactivity.

also u can refer this demo project

Scanner.nextLong() will stop reading as spaces (or other non-digit characters) are encountered.
For instance, if the input is 1234 567 .. then nextLong() will only read 1234.
However, while spaces in the credit-card will [likely] cause it to fail LUHN validation with the above code, I make no guarantee that removing the spaces would make it pass - I'd use a more robust (and well-tested) implementation from the start. There is no need to rewrite such code.

Application randomly stops responding.

I am new to programming and I'm making a very simple blackjack game with only basic functions. When I run the program on the emulator it runs maybe for one hand, two, sometimes 5 or more but it always stops responding at some stage when i click on one of the three butons. There is a splash screen that runs for three seconds and the there is a thread comming from that activity that starts this menu activity. Could anyone maybe tell why this is happening? It usually happens when I clcik on one of the buttons even though there is no much comput
