Permission for publish stream is not being done properly

I have made an application that needs me to publish an audio file to facebook, I can successfully publish that but the problem is, when I login to facebook through my application it shows a permission dialog, every thing file till here, 开发者_JAVA百科but when I tap the "Allow" button on the publish dialog it shows the error message that user hasn't authorized you publishing permission(even I clicked Allow). But for the second time when I log in to facebook, it doesn't show me the permission dialog and the audio file get successfully published.

I can't find where the problem is. Please help me!!
