我正在寫一些文本到文件中,但在寫入文本之前,我無法創建文件本身。無法創建文件 - EACCESS權限被拒絕
File newxmlfile = new File(
Environment.getExternalStorageDirectory() + "new.xml");
XmlSerializer serializer = Xml.newSerializer();
try {
newxmlfile.createNewFile();
} catch (Exception e) {
Log.e("IOException", "exception in createNewFile() method",
e);
}
權限設置正常。
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
SDCard也可寫入和安裝。
不過,我一直得到

取而代之的是' Environment.getExternalStorageDirectory()+「\ new.xml」)'試試這個'Environment.getExternalStorageDirectory()+ File.Seperator +「new.xml」)' – Raghunandan
