When I call the API InAppPurchase.instance.makePurchase(productId);
A mistake occurred:event.type:PURCHASE_ERROR,event.data:Error: Service connection is disconnected., BillingResponseCode: -1
When I add the following to Manifest.xml
<application >
<!-- GOOGLE PLAY BILLING -->
<activity
android:name="com.android.billingclient.api.ProxyBillingActivity"
android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:theme="@android:style/Theme.Translucent.NoTitleBar" />
</application>
It's all right.
