更改軟件包名稱時出現奇怪的解析問題

更改我的應用程序的主軟件包名稱時出現奇怪的xml解析問題。在改變它以後，一切都出錯了，我發現從web解析的文本就像垃圾數據一樣。我已經檢查過從哪個RSS數據源解析數據，但它工作正常。而且我的共享偏好不工作，也有mysql數據庫的問題。我附上了截屏（其網格視圖顯示新聞標題）。請看看。我也附上代碼來解析XML。任何幫助將是提前appreciated..Thanks ...更改軟件包名稱時出現奇怪的解析問題

你怎麼改包的名字嗎？嘗試回滾你的項目，看看它是否可以再次運作 –

是的，當我回滾時它的工作正常。但它非常重要，我必須更改軟件包名稱......我首先將其從androidtools->重命名軟件包名稱更改。改變它後，我發現它在某些類中沒有改變。所以我重命名了根文件夾（com.app）也...之後，問題發生 –

好吧，聽起來不錯，嘗試在所有類中搜索您的舊包名 –
