I was reading the documentation for recording audio and video (http:// developer.android.com/guide/topics/media/index.html) and noticed a few problems:
Video and image capture are not described even though MediaRecorder's documentation directs readers to this page for more information. Through other websites, I discovered that video capture is a fair bit more involved and has a number of gotchas compared to audio capture. For example, the internet seems to hold that for now a valid preview surface is counterintuitively required for video capture (http:// stackoverflow.com/questions/1032912/android-does-anyone-know-how-to- capture-video/1592917#1592917). It would be nice if these quirks were documented on this page. The code listed in the example is not correct (as of API version 7 -- I also checked some of these against the most recent API, but not all of them). - MediaStore.MediaColumns does not contain a TIMESTAMP field. (I think DATE_ADDED is what's actually there.) - MediaStore.Audio does not have an INTERNAL_CONTENT_URI field. - ContentResolver is an abstract class that cannot be instantiated. - ContentResolver does not have a getDataFilePath method. - MediaRecorder does not have a getMimeContentType method, or any other method that performs this function. - A comment in the example suggests that the preview display is optional, which according to all the information I referred to earlier it is not. This whole section of the docs could use a lot more detail. Maybe links to the android camera application source would also be helpful (http://android.git.kernel.org/?p=platform/packages/apps/ Camera.git;a=blob;f=src/com/android/camera/ Camera.java;h=523df5f06ccd97314006bf655a86f453914cb86b;hb=master). -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
