Writing To File Not Working In Android

I am trying to write to a text file in Android. My code is as follows (running in a Service): File log; String state = Environment.getExternalStorageState();

Solution 1:

If it's a real device (not AVD), then I think it's plugged into your computer via USB. Some settings doesn't allow to browse external storage while it's plugged to a computer. Unplug it, and look for the file.

Solution 2:

i have rooted 4.2.1 GNexus and here's how i find that 'External' directory for 'Movies'...

127|shell@android:/storage # busybox find . -type l   // list symlinks in /storage                          
./sdcard0
./emulated/legacy
shell@android:/storage # ls -l sdcard0      // list the symlink for SDCRD

lrwxrwxrwx root     root              2013-02-12 06:57 sdcard0 -> /storage/emulated/legacy

shell@android:/storage # ls -l /storage/emulated/legacy  // follow it                        
lrwxrwxrwx root     root              2013-02-12 06:57 legacy -> /mnt/shell/emulated/0

shell@android:/storage # ls -l /mnt/shell/emulated/0
