android ANR BillingClient.queryPurchases

Question

I am using Google billing service, version 2.0.3. Running the BillingClient.queryPurchases method in the UI thread in the activity onstart method, users sometimes encounter Application Not Responding errors like this:

THREADS:

What is the best way to fix this type of ANRs?

Answer 1

Since Version 4.0.0 of the Google Play Billing Library you can use BillingClient.queryPurchasesAsync().
BillingClient.queryPurchases() will be removed in a future release.

implementation("com.android.billingclient:billing:4.0.0")

billingClient.queryPurchasesAsync(BillingClient.SkuType.INAPP, (billingResult1, list) -> {
    ...
});
