java.io.FileNotFoundException with FileWriter

The following line

FileWriter fw = new FileWriter("/log0.txt");

throws:
java.io.FileNotFoundException: /log0.txt (Read-only file system)

I'm testing this on device and "USB storage" is off. Any idea why this happens?

You are trying to create a file in the root path "/". Try to create the file in a writable path like "/data/" or "/mnt/sdcard" or use the methods: Environment.getExternalStorageDirectory()
