[android-developers] Re: ContentResolver insert return null on 4.3

I just had a quick peek at the API level 14 source code and it looks like there are two possible reasons for that problem:

1. The actual ContentProvider the ContentResolver connected to returns null on insert (for whatever reason, that is a mystery)
2. A RemoteException was thrown during the insert operation. The exception is caught by the ContentResolver and it returns just null instead. The reason for that is (according to the source code comment) that the process / app is about to die anyway.

Other ContentResolver methods behave exactly the same. Also the query methods. It can - without a warning - just return null, even though it works in your tests a million times.

You therefore need to check the result for null and come up with a strategy for coping with that problem, like scheduling a re-query or checking if your activity is about to be finished.

This code works on all Android versions except on 4.3:

                           ContentValues content = new ContentValues(4);

           content.put(Video.VideoColumns.TITLE, "vid.mp4");

           content.put(Video.VideoColumns.DATE_ADDED,

           System.currentTimeMillis() / 1000);

           content.put(Video.Media.MIME_TYPE, "video/mp4");

           content.put(MediaStore.Video.Media.DATA, "/sdcard/vid.mp4");

           ContentResolver resolver = getContentResolver();

           Uri uri = resolver.insert(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,

           content);

On 4.3 uri is null.

Can someone help?

Thanks,

Eli
