How to fix Integer.intValue() for RTL languages in Android

In my application I write some codes and this codes I used string.
I want use UTF-8 languages (Farsi), But after run application show me error and force close application.
But when use English language not show me any error and run successfully!!
My codes :
this.q.put("dry land swim", Integer.valueOf(R.array.dry_land_swim));
TypedArray obtainTypedArray = getResources().obtainTypedArray(((Integer) this.q.get(stringArray[i])).intValue());
int length = obtainTypedArray.length();
int[] iArr2 = new int[length];
WorkoutData workoutData = new WorkoutData();
for (int i2 = 0; i2 < length; i2++) {
iArr2[i2] = obtainTypedArray.getResourceId(i2, -1);
}
workoutData.setExcName(stringArray[i]);
Log.e("ShowError", "" + (this.r.get(stringArray[i])).intValue());
workoutData.setExcDescResId(((Integer) this.r.get(stringArray[i])).intValue());
When change this line text (from En to Fa) :
this.q.put("تست", Integer.valueOf(R.array.dry_land_swim));
Show me error for this lines :
TypedArray obtainTypedArray = getResources().obtainTypedArray(((Integer) this.q.get(stringArray[i])).intValue());
workoutData.setExcDescResId(((Integer) this.r.get(stringArray[i])).intValue());
Error message :

Getting the cover image of song from local media

ContentResolver musicResolver = getContentResolver();
Uri musicUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
Cursor musicCursor = musicResolver.query(musicUri,null,null,null,null);
if(musicCursor!=null && musicCursor.moveToFirst()){

//Add songs to the array list
do{

ArrayList just recognise the first element

I have an ArrayList that I add some data in a method, when I try to remove a item that isn't the first one I get the following error

But if I check the size of the array, that indicates a number uppon one
My code to delete:
public static ArrayList<String> hasKeys = new ArrayList<>();
...
private void deleteTeam(int indexRemove){
Log.e("[HAS CHECK]", hasKeys.size() + "");
for(int i = 0; i < hasKeys.size(); i++){
Log.e("[CHECK INDEX]", hasKeys.get(i));
Log.e("[CHECK INDEX]", i + "");
}
// Log.e("[CHECK INDEX]", hasKeys.indexOf(m_orders.get(indexRemove).getTeamName()) + "");
hasKeys.remove(hasKeys.indexOf(m_orders.get(indexRemove).getTeamName()) - 1);
Menu.teams.remove(m_orders.get(indexRemove).getTeamName());
m_orders.remove(indexRemove);
m_adapter.removeItem(indexRemove);
m_adapter.notifyDataSetChanged();
}
I'm using the following code to add items to it
m_orders = new ArrayList<Teams>();
Teams o1 = new Teams();
hasKeys.add(teamName.getText().toString());
Log.e("[HAS CHECK]", hasKeys.size() + "");
o1.setTeamName(teamName.getText().toString());
o1.setTeamPlayers(playerOne.getText().toString() + ", " + playerTwo.getText().toString() + ", " + playerThree.getText().toString() + ", " + playerFour.getText().toString() + ", " + playerFive.getText().toString());
Menu.teams.put(o1.getTeamName(), o1.getTeamPlayers());
m_orders.add(o1);

This is happening because your item is always added at index 0. The size of array list is 1 every time from your add items. I don't know the exact flow of your code. But it's seems like if you are calling below statement every time:
m_orders = new ArrayList<Teams>();
This is instantiating your array list.

How to use a Cursor?

I have an app that receives the id of an animal and pass that id to a method from the database that will be read several times in a do-while. I want to know why this error happens?
This is my code:
bd = new BaseDados(getApplicationContext());
Cursor cc = bd.getIdAnimal(chipnumber);
if (cc.moveToFirst()) {
idanimal = cc.getInt(cc.getColumnIndex("idanimal"));
}
Cursor ccc = bd.getGruupsnosAnimals(idanimal);
do{
if(ccc.moveToFirst()){
String groupname= ccc.getString(ccc.getColumnIndex("groupname"));
}
}while (ccc.moveToNext());
This is my error:

Exception: not an error? That's a new one.
Your bottom loop is a bit weird and may be a bug- you're moving to next but may not even have moved to first if that failed. And if it succeeded you'll infinitely loop. Try this instead:
if(ccc.moveToFirst()){
do{
String groupname= ccc.getString(ccc.getColumnIndex("groupname"));
}while (ccc.moveToNext());
}

do{
if(ccc.moveToFirst()){
String groupname= ccc.getString(ccc.getColumnIndex("groupname"));
}
}while (ccc.moveToNext());
this is an infinite loop, while you have next item in your cursor, you move to first one, and next iteration you would again move to first one.
Also do not forget to call Cursor.close() after usage.

Try this:
// Move the cursor to the first row if cursor is not empty
if(ccc.moveToFirst()) {
do{
String groupname= ccc.getString(ccc.getColumnIndex("groupname"));
}while (ccc.moveToNext()); // Move cursor to next row until it pass last entry
}
Instead of:
do{
if(ccc.moveToFirst()) {
String groupname= ccc.getString(ccc.getColumnIndex("groupname"));
}
}while (ccc.moveToNext());

Remove extra dots in float value before a separater " , " occurs using java

I am generating a statistical calculator application.
So I want to format input from edittext like this
i/p = 3.5.6, 6.5 to 3.5 , 6.5
Using " , " (comma) as separator so splitting the input string to float array when a " , " occurs.
I want to ignore 3.5[.6] and generate array like this
s[1] = 3.5 , s[2] = 6.5
While calculating mean application crashes due to extra " . " dots.
s = it.getText().toString(); //"it" is edittext
s=s.replaceAll( ",+" , "," );
String[] strarray =s.split(",");
float[] farray = new float[strarray.length];
for(int i = 0; i < strarray.length; i++)
{
farray[i] = Float.parseFloat(strarray[i]);
}

Force finishing activity com.cal.mc2/.Mean

How about this simple function (IdeOne link here: https://ideone.com/utKPjP):
public static float myParseFloat(String str) {
int firstDot = str.indexOf('.');
if (firstDot != -1) {
int secondDot = str.indexOf('.', firstDot+1);
return Float.parseFloat(secondDot == -1 ? str : str.substring(0,secondDot));
}
return Float.parseFloat(str);
}
Then you just replace this statement in your code:
farray[i] = Float.parseFloat(strarray[i]);
with:
farray[i] = myParseFloat(strarray[i]);

You can use regex like this :
public static void main(String[] args) {
String s = "3.5.6, 6.5";
s = s.replaceAll("(?<=\\d\\.\\d)\\.\\d", "");// positive look behind. Only replace `.[digit]` if it is preceeded by [digit][.][digit]
System.out.println(s);
String[] arr = s.split(",");
System.out.println(Arrays.toString(arr));
}
O/P :
3.5, 6.5 --> value of s after replacement
[3.5, 6.5] --> array contents
