マインアクティブの基本/プレミアムコンテンツへのユーザーアクティブサブスクリプションかどうかを調べたいです。サブスクリプションプロセスを開始するBillingClientLifecycle
クラスがあります。私が理解しているように、queryPurchses
ユーザーにアクティブな購読があるかどうかを表示する必要があります。しかし、(購読状態を表示するために私がそこに置くトーストによって)それは、ユーザーが実際に購読されていない場合でも、ユーザーは購読されています。
public void queryPurchases() {
if (!billingClient.isReady()) {
Log.e(TAG, "queryPurchases: BillingClient is not ready");
}
Log.d(TAG, "queryPurchases: SUBS");
Purchase.PurchasesResult result = billingClient.queryPurchases(BillingClient.SkuType.SUBS);
if (result == null) {
Log.i(TAG, "queryPurchases: null purchase result");
processPurchases(null);
///
Toast.makeText(applicationContext,"queryPurchases: null purchase result", Toast.LENGTH_SHORT).show();
} else {
if (result.getPurchasesList() == null) {
Log.i(TAG, "queryPurchases: null purchase list");
processPurchases(null);
///

} else {
processPurchases(result.getPurchasesList());

BillingClientLifecycle
クラス内の共有環境設定(トーストの代わりに)を使用して、MainActivityクラスまたはその他のクラスからサブスクリプションステータスを取得します。アプリが起動されたときにサブスクリプションステータスの通知が必要です。私は共有環境設定を使用し、直接購読情報を呼び出すことを好みますが。
私はこのライブラリを購入するために使っています、それはあなたに役立つかもしれません。
