comparing dates doesnt work

I've made this function that compares 3 dates but its not working and I cant figure out why. data = 2013-02-10 and data2= 2013-02-14, datateste is the date of the system. it should appear an error alert but it doesn't

 void restricoes()  {
 Button btnCreateProduct = (Button) findViewById(R.id.button2);

     try {
     SimpleDateFormat sdf = new SimpleDateFormat("yyyy/mm/dd");

     java.util.Date strDate1 = sdf.parse(data);
     java.util.Date strDate2 = sdf.parse(data2);
     java.util.Date strDate = sdf.parse(datateste);




     if (strDate.before(strDate1) && strDate.after(strDate2)) {
            Toast.makeText(getApplicationContext(), "chupa boi",
                       Toast.LENGTH_LONG).show();
            Toast.makeText(getApplicationContext(), data,
                       Toast.LENGTH_LONG).show();
            Toast.makeText(getApplicationContext(), data2,
                       Toast.LENGTH_LONG).show();
            Toast.makeText(getApplicationContext(), datateste,
                       Toast.LENGTH_LONG).show();
            inputdata.setError("yipikaei");


     }
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }


if(checkEditText(inputdtestab) || checkEditText(quantidade))
{
    inputdtestab.setError("yipikaei");
    quantidade.setError("mudfukkerrr");
    btnCreateProduct.setVisibility(View.INVISIBLE);

}
else{

     // ==========================================
     // make button visible.
     // use the method "setVisibility", not "setViewVisibility"
     // and "VISIBLE" in "View.VISIBLE" is in full cap:
     btnCreateProduct.setVisibility(View.VISIBLE);
    }
}

so now instead of this i putted the code directly in the oncreate method and it works

try{

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
java.util.Date date1 = sdf.parse(datateste);
java.util.Date date2 = sdf.parse(data);

System.out.println(sdf.format(date1));
System.out.println(sdf.format(date2));

if(date1.compareTo(date2)>0){
    inputdata.setError("asa");
}else{
    System.out.println("How to get here?");
}

  }catch(ParseException ex){
ex.printStackTrace();
  }

but if change the data to not respect the if condition the error alert doesnt disappear

As you said, data = "2013-02-10", but you seem to be parsing with the pattern "yyyy/MM/dd". Try with "yyyy-MM-dd" or change your input data.

Your date format uses this pattern "yyyy/mm/dd". However, mm stands for minutes. If you need months, you need to uppercase it to "yyyy/MM/dd". See the documentation here.

Furthermore, you're checking whether 2014/06/11 is both before 2013/2/10 and after 2013/2/14. That will obviously never be the case.
