解決內部儲存空間緊張，不載入案頭壁紙，案頭壁紙顯示，載入案頭壁紙
說明：
當內部儲存空間不足的情況下不載入壁紙，以節省資源。
修改方式：在WallpaperManagerService.java中進行修改；思路：首先在載入壁紙之前我們需要判斷當前儲存空間是否緊張。代碼如下：（源碼地址）

紅色部分為增加代碼。
我在換電腦案頭背景得時都會出現，儲存空間不足不可以處理命令？是什回事？
不知是我沒看明白,還是你沒有說明白.不解??? 答案補充 一般就是C盤空間的問題!如果你沒有進行設定的話,虛擬記憶體也是在C盤下!正常是要把虛擬記憶體和系統分開放在不同的分區中.像TEMP臨時檔案夾等都要分開放!而且C盤我個人認為最少要分10G的!虛擬記憶體也要設定同一大小(也就是最小值和最大值要相等)! 答案補充 "我的電腦"右鍵-"屬性"-"進階"-"效能"設定-"進階"-"虛擬記憶體"更改
w7案頭壁紙怎設定 顯示出現內部錯誤
在案頭空白處點擊滑鼠右鍵，選擇“下一個案頭背景”，電腦沒反應。2，選擇一張圖片，點擊“設為案頭背景”，顯示“出現內部錯誤”不能成功設定.3，在個人化中選擇其他主題，電腦有換主題的聲音但是案頭背景圖片還是沒有變化。於是我百度之，現將方法帖出來，希望遇到同樣問題的朋友能夠看到，節約寶貴的時間。
解決方案為：開啟以下路徑找到作業系統盤符所在路徑，我的是C盤，建議先開啟檔案夾選項中的作業系統檔案夾隱藏保護和顯示所有檔案夾選項，可以更快的定位檔案夾目錄。在C:\Users\YourUserName\AppData\Roaming\Microsoft\Windows\Themes，找到TranscodedWallpaper.jpg並刪除之，再次切換一個主題就好了。
