file.delete（）错误30

Question

I try to delete a text file I created with:

FileOutputStream fOut = openFileOutput("game.txt", MODE_PRIVATE);

by using

File file = new File(filename);
        if (!file.exists())
        {
        Log.d(TAG,"gonna delete game.txt");
        file.delete();
        }

but keep getting error message:

Unable to unlink '/game.txt': Read-only file system (errno=30)

Do you know what's wrong here?

Answer 1

now it works well. Filename did not contain full path to file (although it's in root directory) it has to have full path

Answer 2

File file = new File(filename);

if (file.exists()){
    Log.d(TAG,"gonna delete game.txt");  
     file.delete(); }

Try this.
