你的onload函數什麼時候被調用？ – wmfairuz
@wmfairuz請看我更新的問題，你會知道的。我在html代碼中的每個標記之前添加了額外的\，因爲它沒有按原樣打印我的代碼。我認爲應該有一些方法來避免這種情況，因爲對於像我這樣的人，誰不知道html，它變得很難避免它 –
我從來沒有見過這些dalvikvm錯誤消息，它讓我覺得可能是什麼你的配置有問題嗎？您是否將目標API級別設置爲最新的Android？另外，這行代碼：''ReferenceError：找不到變量：執行file：///android_asset/www/file_reader.html:12''讓我認爲在JavaScript中你應該調用''cordova.execute'' ''或''window.plugins.Echo（）''？你有沒有創建，你可以粘貼Echo.js文件？ Cordova插件通常應該有兩個文件，一個是Javascript一個，一個是本地文件。 – MBillau
