在寫Android用戶界面的時(shí)候無(wú)法對(duì)數(shù)據(jù)庫(kù)進(jìn)行讀寫，可是SQL語(yǔ)句并沒有寫錯(cuò)是什么原因？

我在寫Android用戶界面的時(shí)候無(wú)法對(duì)數(shù)據(jù)庫(kù)進(jìn)行讀寫，每次點(diǎn)擊注冊(cè)按鈕添加數(shù)據(jù)的時(shí)候應(yīng)用都會(huì)自動(dòng)關(guān)閉，只有應(yīng)用運(yùn)行之后root一下模擬器才可以看到數(shù)據(jù)庫(kù)文件，但是數(shù)據(jù)庫(kù)文件下載下來(lái)打開是亂碼，無(wú)法辨別。我嘗試運(yùn)行過(guò)不同需要操作數(shù)據(jù)庫(kù)的項(xiàng)目都是報(bào)的類似錯(cuò)誤，還請(qǐng)各位大佬看看有啥辦法？下面是錯(cuò)誤信息
