I'm a newbie to mobile app development and I'm trying to follow this tutorial
https://www.dropbox.com/developers-v1/dropins/chooser/android
But the problem is when I click the button "Chooser", it pop-up a message like this so i cannot go to the next step (which is choosing a file).

If I click "Install", the app will crash with this exception: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=market://details?id=com.dropbox.android }
Sorry if I post this question in the wrong place, I couldn't find the solution
