Not connecting with onBillingSetupFinished method

Question

I'm trying to show Toast inside onBillingSetupFinished method but it's never connect with it.

Code

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ActivityMainBinding activityMainBinding = ActivityMainBinding.inflate(getLayoutInflater());
    setContentView(activityMainBinding.getRoot());

    BillingClient billingClient = BillingClient.newBuilder(this).enablePendingPurchases().setListener(this).build();
    billingClient.startConnection(new BillingClientStateListener() {
        @Override
        public void onBillingServiceDisconnected() {
            Toast.makeText(MainActivity.this, "A", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onBillingSetupFinished(@NonNull BillingResult billingResult) {
            Toast.makeText(MainActivity.this, "B", Toast.LENGTH_SHORT).show();
        }
    });

}

@Override
public void onPurchasesUpdated(@NonNull BillingResult billingResult, @Nullable List<Purchase> list) {
    Toast.makeText(this, "C", Toast.LENGTH_SHORT).show();
}

Permissions

<uses-permission android:name="android.permission.INTERNET"/>

I uploaded apk to Google Play Store and they accepted it but code still not working.

Your code works fine. It's just that you are unable to get the toast. There are two things you can do:

Replace the Toast with

Log.d("GoogleBillingService", "onBillingSetupFinished: billingResult: Yes/Your Result");

And check the LogCat at GoogleBillingService to get the results.

The toast is probably running on a different thread and hence you don't see it when you run the application.

Try using

((Activity)context).runOnUiThread(new Runnable()
    {
        public void run()
        { 
             Toast.makeText(context, toast, Toast.LENGTH_SHORT).show();
        }
    });

Hope this helps you out!
