退出應用程序時內存不清除

Question

我已經瀏覽了幾篇文章，並注意到有時在應用程序退出時不會調用onDestroy（）。有時只調用onPause（）。我的整個事情是，當我退出我的應用程序的後退按鈕或完成（）函數，一切都很好。當我嘗試重新打開我的應用時，它說：

12-14 04:09:59.457: E/GraphicsJNI(996): VM won't let us allocate 3279360 bytes 

我也會粘貼整個日誌。事情是當它重新開放時，它就會關閉。之後，我可以重新打開它。例如，無論何時我在Eclipse中重建它並通過模擬器運行它，它都可以正常工作。但是，如果我在應用程序內關閉它並嘗試重新打開它，那就是當我收到此內存問題時。我不確定什麼沒有被清除，我真的希望你們中的一個人有解決方案，或者至少可以指出我解決這個問題的正確方向，因爲這真的讓我頭痛。如果你們需要更多的信息，請讓我知道。謝謝。

Answer 1

嘗試尋找DDMS，它有一個Heap選項卡，告訴你內存分配。

窗口>打開透視圖>其他...

然後選擇DDMS

在我的應用程序之一，我有這個設置的退出按鈕，它會清除返回堆棧和啓動應用中的第一個活動，只需將Main.class替換爲您的第一個活動名稱即可。然後，一旦你點擊後退按鈕的應用程序退出

 Intent intent = new Intent(this, MainMenu.class); 
     intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
     intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
     startActivity(intent);
