to solve this error you must assign a value (True) to the function

Intent pay_intent = new Intent(this, PayActivity.class);
putNormalExtras(pay_intent);


if you use ActionBar assign the value true

pay_intent.putExtra("ActionBar",true);

change the AppTheme to any ActionBar Theme

for example :

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
