Ioexception: Permission Denied

I am trying to write a file to the external storage of the android. On the AndroidManifest.xml I've added (within the manifest tag)

Oh, and I would modify your code in a next way:

if(root.canWrite()){
    Filefile=newFile(root, "file.xml");         
    file.createNewFile();
}

Solution 2:

Do you have the permissions set in the manifest?

<uses-permissionandroid:name="android.permission.WRITE_EXTERNAL_STORAGE" />

You can also just replace "root" with your call to get the directory rather than declaring it. What is the value of xmlFilename?

Solution 3:

Ensure you have the correct permissions to write to the file. In your manifest file, include this line

<uses-permissionandroid:name="android.permission.WRITE_EXTERNAL_STORAGE" />.
