• Login in your app: http://dev.twitter.com/apps
• In the Settings tab, change the Application type to Read, Write and Access direct messages
• In the Reset keys tab, press the Reset button, update the consumer key and secret in your application accordingly.

It looks like that resetting the keys force the change to your application type to take effect.

Go to https://dev.twitter.com/ -> My Applications -> "go to your current application" -> Setting -> Give the permission for "Read, Write and Direct Access" -> Save it. After that uninstall your project from emulator or device, -> Clean project -> Run Project.

You also have to revoke your old permission after you reset your permission.

1. Go to https://twitter.com/settings/applications
2. Find your app and you will see that it has read permission
3. Revoke the access
