android - Format a french phone number -

i have format "0612345678" "06 12 34 56 78".
i'm using :

private string formattel(string number) {     try {         string formattednumber = "";         int i;         (i = 0; < 10; += 2) {             formattednumber += number.substring(i, + 2) + " ";         }         return formattednumber.substring(0, formattednumber.length() - 1);     } catch (indexoutofboundsexception e) {         return number;     } } 

it works on emulator running api 16 (jellybean 4.1.1) : on it, result looks want ("06 12 34 56 78") on own phone, (api 22, lollipop 5.1.1), doesn't work : result "0 61 23 45 67" whereas method same !

i did research , i've found string.format method. it's here need help, it's hard me... !

thank in advance :d

edit :

working method, using libphonenumber :

private string formattel(string number) {     string formattednumber = number;     try {     phonenumberutil phonenumberutil = phonenumberutil.getinstance();     phonenumber.phonenumber numberproto;         numberproto = phonenumberutil.parse(number, "fr");         formattednumber = phonenumberutil.format(numberproto, phonenumberutil.phonenumberformat.national);     } catch (numberparseexception e) {         e.printstacktrace();     }     return formattednumber; } 

thank ye lin aung !

i've tried code on lollipop phone , works expect.

alternatively, i'd suggest use libphonenumber parse phone numbers whenever comes phone number. here's how done.

try {   phonenumberutil phoneutil = phonenumberutil.getinstance();   phonenumber.phonenumber numberproto;   numberproto = phoneutil.parse("+330612345678", "");   log.i("code",       "code " + phoneutil.format(numberproto, phonenumberutil.phonenumberformat.national)); } catch (numberparseexception e) {   e.printstacktrace(); } 

which result

 i/code﹕ code 06 12 34 56 78
