question

This is my cash drawer code (API Level 17 model C100):

added dependancy we getting crash when runing application:

android:name="clover.permission.POP_CASH_DRAWER_NEW"

public void onOpenCashDrawerClick() {
    Context appCt = getApplicationContext();
    CashDrawers cds = new CashDrawers(appCt);
    Log.i("onOpenCashDrawerClick", String.valueOf(cds.list().size()));

    for (int i = 0; i <  cds.list().size(); i++)
    {
        Log.i("inside1for",String.valueOf(i));
        cds.list().iterator().next().pop();
    }

    Set<CashDrawer> drawers = new CashDrawers(appCt).list(); // get the set of connected cash drawers
    for (CashDrawer cd : drawers) {
        Log.i("inside2for", String.valueOf(cd.getDrawerNumber()));
        cd.pop(); // pop each connected cash drawer
    }
