Im currently playing with file downloads. But I'm currently facing a weird error :

Here's my code : 

458    FileChannel outChannel = new FileOutputStream(mediaFileName).getChannel();

And then I do other stuffs but I think the new FileOutputStream is where it crashes. One the character (surely the *) is in cause but I don't understand why and how I can make it work (since on android with adb shell, i can create a file with this name). Any idea ? thanks

    See [this question](http://stackoverflow.com/questions/2679699/what-characters-allowed-in-file-names-on-android). Why not renaming? – Knickedi May 23 '12 at 16:40
  • Thanks. The filename is selected by the user of my app. – Gomoku7 May 23 '12 at 16:43
  • I dont get it. I can adb shell on my phone and create the file with this very same name... Why does it crash ? – Gomoku7 May 23 '12 at 16:48

    I can create such a file via adb shell only if the filesystem supports that name (e.g. ext4 does) : `touch "\"Samsung ()+-\* Samsung.jpg\""` works on internal storage (ext4), but does not in `/mnt/sdcard/` since that is FAT which does not support those characters. – zapl May 23 '12 at 17:28
