    public class Vip extends AppCompatActivity implements View.OnClickListener, BillingProcessor.IBillingHandler{
    BillingProcessor bp;
    String KEY="";
    String SKU="buy_gold";
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.vip);
    ((TextView)toolbar.findViewById(R.id.tb_textView)).setText("");
    ((ImageView)toolbar.findViewById(R.id.tb_imageView)).setOnClickListener(this);
    bp = new BillingProcessor(this, KEY, this);
}

@Override
public void onClick(View v) {
    switch (v.getId()){
        case R.id.tb_imageView:
            bp.purchase(Vip.this,SKU);
            break;
    }
}

@Override
public void onProductPurchased(String s, TransactionDetails transactionDetails) {
    Log.e("asd",s+"  "+transactionDetails.toString());
}

@Override
public void onPurchaseHistoryRestored() {
