Luxand API for similarity on android

I'm going to use Luxand api for detect persons.
Scenario:
1- At the first on register activity persons sit in front of the camera and take pictures and templates save on sqlite database. also personal information will be save;
2- After that On detect activity one of them sit in front of the camera and take Auto detection and find same temp and show person information.(similarity is 96%)
my problem:Unfortunately too times detection is wrong and two different people’s templates will be recognized as the same person.
My Code:
1- Register activity for register form
for (int i = 0; i < MAX_FACES; ++i) {
if (rects[i] != null && rects[i].x1 <= x && x <= rects[i].x2 && rects[i].y1 <= y && y <= rects[i].y2 + 30) {
mTouchedID = IDs[i];
mTouchedIndex = i;
temp = (byte[]) ImageFrameFaceIDTemps.get(mTouchedID);
if (mPreview != null) {
onTouchMode = true;
try {
requesting name on tapping the face
if (faceSelected != null) {
faceSelected.Selected(temp, data);
}
} finally {
onTouchMode = false;
}
}
break;
}
2- Detection activity for match form
public int RetrievePersonDetection(byte[] template, float[] maxSimilarity_UnderAccepted, float[] maxSimilarityArray) {
if (IDTemps == null || IDTemps.size() == 0) {
return 0;
}
int person = 0;
FSDK_FaceTemplate currentFaceTemp = new FSDK_FaceTemplate();
currentFaceTemp.template = template;
float[] similarityArray = new float[1];
float maxSimilarity = 0;
float MatchingThreshold[] = new float[1];
FSDK.GetMatchingThresholdAtFRR(LocalSetting.MIN_ACCEPTED_SIMILAITY, MatchingThreshold);
for (int i = 0; i < IDTemps.size(); i++) {
long key = IDTemps.keyAt(i);
FSDK_FaceTemplate faceTemp = (FSDK_FaceTemplate) IDTemps.get(key);
int result = FSDK.MatchFaces(currentFaceTemp, faceTemp, similarityArray);
if (result == 0) {
if (maxSimilarity < similarityArray[0] && similarityArray[0] >= MatchingThreshold[0]) {
maxSimilarity = similarityArray[0];
person = (int) key;
maxSimilarityArray[0] = similarityArray[0];
FSDK_FaceTemplate currentFaceTemp2 = new FSDK_FaceTemplate();
}
else if (maxSimilarity_UnderAccepted[0] < similarityArray[0]) {
maxSimilarity_UnderAccepted[0] = similarityArray[0];
}
}
}
return person;
}
I don't no what's my problem? why return wrong person and 2 person similarity is 96%

Radio Button auto deselect after selection

I have four radio buttons in a radio group in my MCQ app. When I select a radio button and go to next question, there is a problem if I select same radio button as previous, the radio button automatically deselect, but after selecting any other button, it is working.
private int getSelectedAnswer(int radioSelected){
int answerSelected = 0;
if(radioSelected == R.id.radio0){
answerSelected = 1;
}
if(radioSelected == R.id.radio1){
answerSelected = 2;
}
if(radioSelected == R.id.radio2){
answerSelected = 3;
}
if(radioSelected == R.id.radio3){
answerSelected = 4;
}
return answerSelected;
}
private void selectedRadioButton(int ansSelected){
if(ansSelected == 1){
optionOne.setChecked(true);
}
if(ansSelected == 2){
optionTwo.setChecked(true);
}
if(ansSelected == 3){
optionThree.setChecked(true);
}
if(ansSelected == 4){
optionFour.setChecked(true);
}
}
private void uncheckedRadioButton(){
optionOne.setChecked(false);
optionTwo.setChecked(false);
optionThree.setChecked(false);
optionFour.setChecked(false);
}
private void showQuestions(){
if(currentQuizQuestion >= quizCount){
currentQuizQuestion=currentQuizQuestion-1;
Toast.makeText(ShowSingleQuestionsOnline.this, "End of the Quiz Questions", Toast.LENGTH_LONG).show();
return;
}
else {
uncheckedRadioButton();
quizQuestion.setText(1+ currentQuizQuestion + " : " + MyQuestArrList.get(currentQuizQuestion).get("QuestName"));
int dd=Integer.parseInt(MyQuestArrList.get(currentQuizQuestion).get("QueType"),10);
optionOne.setText(MyQuestArrList.get(currentQuizQuestion).get("QueOption1"));
optionTwo.setText(MyQuestArrList.get(currentQuizQuestion).get("QueOption2"));
optionThree.setText(MyQuestArrList.get(currentQuizQuestion).get("QueOption3"));
optionFour.setText(MyQuestArrList.get(currentQuizQuestion).get("QueOption4"));
}
}
Thanks in advance.

This behavior is normal because the radio option state is not reset.
Take a look on your getSelectedAnswer() method :
private int getSelectedAnswer(int radioSelected){
int answerSelected = 0;
if(radioSelected == R.id.radio0){
answerSelected = 1;
}
if(radioSelected == R.id.radio1){
answerSelected = 2;
}
if(radioSelected == R.id.radio2){
answerSelected = 3;
}
if(radioSelected == R.id.radio3){
answerSelected = 4;
}
return answerSelected;
}
When you go to the next question, the selected radio option state remain and when you click again on it, it value change (deselect).
To avoid this, you need to reset your radio options before go to the next question.

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. But even if i give valid card number it shows invalid.While entering card number i have given spaces in between i didn't know because of that its not validating properly. Please help me in finding the mistake.

}
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.

Whenever I click on the button, just like in mine sweeper game, many buttons are randomly opened. And when it is opened, I am changing its background into R.drawable.affected. The goal of the game is to open all the buttons in left and right. My question is this, how can I check if all of the buttons are set in R.drawable.affected? Because after that, I will execute a method that will congratulate the user. Thanks in advance.
EDIT:
for (int i = 0; i < btn_right.length; i++) {
final int a = i;
int counter_total_affected = 0;
btn_right[i].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (counter == 1) {
right_lung.add(a);
btn_right[a].setBackgroundResource(R.drawable.affected);

right_lung.add(a + n);
}
try {
for (int i = 0; i < 2; i++) {
int n = i;
btn_right[a + n].setBackgroundResource(R.drawable.affected);
counter_total_affected++;
}
} catch (Exception e) {
e.printStackTrace();
}
} else if (counter == 3) {
right_lung.add(a);
btn_right[a].setBackgroundResource(R.drawable.affected);
counter_total_affected++;
} else if (counter == 4) {
for (int i = 0; i < 25; i++) {
int n = i;
right_lung.add(a + n);
}
try {
for (int i = 0; i < 25; i++) {
int n = i;
btn_right[a + n].setBackgroundResource(R.drawable.affected);
counter_total_affected++;
}
} catch (Exception e) {
e.printStackTrace();
}
} else if (counter == ...) {
//statements...
} else if (counter_total_affected == (btn_left.length + btn_right.length)) {
//CONGRATULATORY METHOD
}
counter++;
}
}

Increment the counter each time you change background of button and compare its value with length of button array. if both are same that means, all button backgrounds are set.
Try this :
for (int i = 0; i < btn_right.length; i++) {
final int b = i;
btn_right[i].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if btn_right[i].getDrawable().getConstantState().equals
(getResources().getDrawable(R.drawable.affected).getConstantState()))
{
if(counter == btn_right.length){
//Congratulate user...
}
}else{
btn_right[b].setBackgroundResource(R.drawable.affected);
counter++;
}
}
}

U can set Tag:
for (int i = 0; i < btn_right.length; i++) {
final int b = i;
btn_right[i].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (counter == 1) {
right_affected.add(b);
btn_right[b].setBackgroundResource(R.drawable.affected);
btn_right[b].setTag('1');
} else {
//some stuff here...
}
}
}
after congratulate the user set its Tag to 0.
EDIT:
ArrayList<Integer> arrayofId =new ArrayList<Integer>();
#Override
public void onClick(View v) {
if (counter == 1) {
right_affected.add(b);
btn_right[b].setBackgroundResource(R.drawable.affected);
arrayofId.add(b);//need to convert int to Integer.
} else {
//some stuff here...
}
}
To congratulate:
for(int i=0;i<arrayofId.size();i++)
{
// you can get here id of effected buttons
}

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
