Android IAB - 成功購買后銷毀活動

Question

我把頭發拉出來！ 在上周的某個時刻，我有這個工作。

我有一個Android應用程序，我試圖添加in-ap計費。 我跟着示例TrivialDrive，我的代碼工作了幾次。 現在它沒有。

我正在創建一個簡單的瑣事游戲，其中包含許多免費問題，以及升級選項以獲得更多問題。 當用戶完成免費問題列表時，他們將被帶到“游戲結束”屏幕，在那里他們可以刪除他們的答案並重新開始或升級。

當我點擊“升級”按鈕時，我可以成功購買，但只要Google“付款成功”對話框消失，我的活動就會被銷毀，我會被發回我的主要活動。

當我嘗試返回並再次購買時，我的代碼會捕獲錯誤（“您已擁有此項目”）並正確處理。 我的代碼向用戶解釋他們已經擁有升級，並允許他們單擊按鈕繼續播放。 所以看起來OnIabPurchaseFinishedListener此時正在觸發。

我已使用最新文件更新了Google幫助程序代碼。

任何有關在何處尋找答案的幫助或建議都非常感謝。

謝謝。

這是我活動的相關代碼：

Answer 1

僅供參考：我想我已經想到了這一點 - 對於任何可能遇到它的人。

我用於啟動“In App Billing”的活動是使用“FLAG_ACTIVITY_NO_HISTORY”調用的。 我這樣做是因為我不希望用戶能夠點擊返回到“Game Over”活動。

但是，這會導致“In App Billing”的悲痛。 因此，請確保您不要嘗試從已設置“FLAG_ACTIVITY_NO_HISTORY”的活動啟動“In App Billing”。

我原來的代碼：

private void GameOver()
    {
        m_TriviaAppInstance.setGameOver(true);
        Intent gameOver = new Intent(getApplicationContext(), GameOverActivity.class);
        gameOver.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
        startActivity(gameOver);
    }

更新的代碼：

private void GameOver()
    {
        m_TriviaAppInstance.setGameOver(true);
        Intent gameOver = new Intent(getApplicationContext(), GameOverActivity.class);       
        startActivity(gameOver);
    }

和平

Answer 2

我不高，不能評論，但祝福你。 我有

android:noHistory="true"

在AndroidManifest.xml中為我的活動設置並遇到了同樣的問題。

拿出來，IAB正在工作。 好極了！

Answer 3

不要忘記您的IabHelper.OnIabPurchaseFinishedListener是在另一個線程上調用的，並且在您的Activity上調用onResume（）之前！

因此，您的UpgradeComplete（）或UpgradeError（）可能會導致舊設備崩潰（每次在我的Gingerbread Sony Xperia Mini Pro上崩潰，並且在三星Galaxy S4（Android 4.2.2）上沒有任何問題。
