Copy the shared preferences XML file from /data on Samsung device failed

Question

There's an exporting feature in my application. It's just a copy operation since all my settings are store in shared preference.

I just copy the xml file from /data/data/package.name/shared_prefs/settings.xml to SD card. It works fine on my HTC desire. However, it might not work on Samsung devices, and i got the following error while I try to copy the file.

I/System.out( 3166): /data/data/package.name/shared_prefs/settings.xml (No such file or directory) 
in the directory.

Anyone know how to fix it, or is there another simple way to store the shared preference ?

Thanks.

Answer 1

Never never never never never never never never never hardwire paths.

Unfortunately, there's no getSharedPreferenceDir() anywhere that I can think of. The best solution I can think of will be:

new File(getFilesDir(), "../shared_prefs")

This way if a device manufacturer elects to change partition names, you are covered.

Try this and see if it helps.

Answer 2

Try using

context.getFilesDir().getParentFile().getAbsolutePath()
