Anjlab libary

    @Override
                public void onProductPurchased(@NonNull String productId, @Nullable TransactionDetails details) {

                    if (productId.toString().equals("sinirsiz")) {
                    //It's need to give vip status to user but is didn't.I can't see any difference on firebase database.

                       myRef.child("Kullanıcılar").child(mAuth.getCurrentUser().getUid()).child("Kredi").setValue(Integer.toString(90000));
                        myRef.child("Kullanıcılar").child(mAuth.getCurrentUser().getUid()).child("VIP").setValue("Yes");
                        myRef.child("LIMITSIZLER").child(mAuth.getCurrentUser().getUid()).child("VIP").setValue("Dogrudur");
                        Toast.makeText(Buy.this, "VIP account enabled", Toast.LENGTH_SHORT).show();
                        startActivity(new Intent(getApplicationContext(), AnaEkran.class));
                    }  else if (productId.toString().equals("vip")) {
            //Same problem here.
                        myRef.child("Kullanıcılar").child(mAuth.getCurrentUser().getUid()).child("Kredi").setValue(Integer.toString(900));
                        myRef.child("Kullanıcılar").child(mAuth.getCurrentUser().getUid()).child("VIP").setValue("Yes");
                        myRef.child("VIPBABALAR").child(mAuth.getCurrentUser().getUid()).child("VIP").setValue("Aynen");
                        Toast.makeText(Buy.this, "VIP account enabled", Toast.LENGTH_SHORT).show();
                        startActivity(new Intent(getApplicationContext(), AnaEkran.class));
                    }  else if (productId.toString().equals("minivip")) {
                        //And here


                        myRef.child("Kullanıcılar").child(mAuth.getCurrentUser().getUid()).child("Kredi").setValue(Integer.toString(210));
                        myRef.child("Kullanıcılar").child(mAuth.getCurrentUser().getUid()).child("Minivip").setValue("Yes");

                        myRef.child("Minivipler").child(mAuth.getCurrentUser().getUid()).child("Minivip").setValue("Aynen");
                        Toast.makeText(Buy.this, "VIP account enabled", Toast.LENGTH_SHORT).show();
                        startActivity(new Intent(getApplicationContext(), AnaEkran.class));
                    }
                }

                @Override
                public void onPurchaseHistoryRestored() {

                }

                @Override
                public void onBillingError(int errorCode, @Nullable Throwable error) {

                }

                @Override
                public void onBillingInitialized() {

                }

I recived payment succesfuly.I can see the play console user has purcahed to item,but they don"t get the vip.The vip function it's not triggered for whatever reason.Users has purchased the item but they don't get the status

UPDATE

Somebody give this code on here Is will work like this.Do i need to add anything ?

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (!bp.handleActivityResult(requestCode, resultCode, data))
            super.onActivityResult(requestCode, resultCode, data);
    }
