I tried looking at previous questions and answers but with no luck finding a real solution. I'm acknowledging purchases once they are processed although my users are still automatically refunded. Below is my whole purchase activity. It's a simple activity with a big button to purchase the app's full version. Anoter button to restore previous purchases. A third button to show some advice if users were not able to restore their purchase.
Any help would be appreciated!
public class BuyActivity extends AppCompatActivity {
Button unlock_button;
Button restore_purchase;
static final String PRODUCT_ID = "full_version";
private BillingClient billingClient;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_buy);
unlock_button = findViewById(R.id.unlock_button);
restore_purchase = findViewById(R.id.restore_purchase);
billingClient = BillingClient.newBuilder(getApplicationContext())
.setListener((billingResult, list) -> {
// responds to all purchases that were already made
if (billingResult.getResponseCode()==BillingClient.BillingResponseCode.OK && list!= null) {
for (Purchase purchase:list){
if (purchase.getPurchaseState() == Purchase.PurchaseState.PURCHASED) {
acknowledge_purchase(purchase);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
features_unlocked();
}
},500);
} else {
Toast.makeText(getApplicationContext(), "ERROR OCCURRED", Toast.LENGTH_SHORT).show();
}
}
} else if (billingResult.getResponseCode()==BillingClient.BillingResponseCode.ITEM_ALREADY_OWNED && list!=null) {
