This is it so can u help me
The stack trace states Caused by: java.lang.ArrayIndexOutOfBoundsException: length=9; index=9
You are calling this code
for(int i=0;i<10;i++){
HashMap<String, String> hm = new HashMap<String,String>();
hm.put("txt", countries[i]);
hm.put("cur", currency[i]);
hm.put("flag", Integer.toString(flags[i]) );
aList.add(hm);
}
Your various arrays (countries, currency, flags) have 9 elements, yet you clearly loop 10 times, hence you are getting the exception. I would suggesting replace 10 with countries.length
This is super simple java and really has nothing to do with the question asked. Simply readying the stack trace would have pointed you in the right direction.
