安卓內存不足setContentView

Question

我已經制作了一個全屏的點擊型應用程序，它有6個屏幕。該應用程序從屏幕上點擊一下。每個屏幕都有自己的活動（步驟1，步驟2，步驟3等到步驟6）。沒有什麼複雜的，佈局非常簡單，只有一個背景圖片和一個按鈕。當問題開始時，我開始關注屏幕3，突然顯示下一個屏幕，但是應用程序在內存不足錯誤中崩潰。我試過移動到屏幕4，5，6，沒有運氣，但如果我移回來從屏幕3說屏幕2，那麼它的工作原理！有東西泄漏，但我不知道是什麼。背景圖像很小。

我活動之間進行切換使用此代碼：

Intent myIntent = new Intent(Step3.this, Step6.class); 
Step3.this.startActivity(myIntent); 
System.gc(); 

這是日誌：

編輯：我創建的六個屏幕類似的應用程序，只需用的TextView和一個按鈕和導航鏈（1 - > 2 - > 3 - > 4 - > 5 - > 6 - > 1），沒有任何圖像，它的作品像黃油。 （如預期）。所以這絕對是與圖像佔用大量內存有關。

Answer 1

recycle()你的位圖，只要你離開一個活動去其他和重新排列代碼：

bitmap.recycle(); 
System.gc(); 
Intent myIntent = new Intent(Step3.this, Step6.class); 
Step3.this.startActivity(myIntent); 

Answer 2

有幾件事情來看待。

• 你提供了幾種密度的背景圖嗎？縮放有時會消耗大量內存。
• 您是否使用startActivity或startActivityForResult()？在後一種情況下，舊的Activity對象不能被銷燬。
• 您是否收集Application課程中的信息？
