The problem was in this code(when I posted question I have seen it. That's absolutely blowing)
private void parseUrl(String url) {
try {
if(url==null)
return;
if(!url.contains("error=")){
Intent intent=new Intent();
intent.putExtra(REDIRECT_URL, url);
setResult(Activity.RESULT_OK, intent);
}
/* I finished app every time page loaded! What a shame */
finish();
} catch (Exception e) {
e.printStackTrace();
}
}
