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:
    "main" prio=5 tid=1 TimedWaiting
      | group="main" sCount=1 dsCount=0 obj=0x73b04268 self=0xa5905400

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

Thats nice! But what is your question? – Monograph

I'm getting thousands of these. Did you figure out what it was? – Taxpayer

Just run it in a separated Thread or AsyncTask – Grogshop

@LluisFelisart the docs of BillingClient explicitly say that the call must be made on the UI thread. – Taxpayer

queryPurchasesdoes not use a listener like other BillingClient methods, if it takes a long time to execute the UI thread blocks. I call queryPurchases in a separate thread on my apps and I never had problems – Grogshop

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) -> {
    ...
});
