I am writing a file to SDCard and set <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> it works good upto 3.x but on 4.0 it gives the below error.

Latter on I discovered that the issue is device specific. I installed the File Manager app from Android market and it shows no write permission. It mean the Android OS implementation of that manufacturer do not provide write permission which is causing the issue.
