Android ContentResolver crash

Question

I am trying to capture mms events in android- I have a ContentResolver which I am setting as follows:

final String[] projection = new String[] { "retr_st", "date", "_id", "ct_t" };
Uri uri = Uri.parse("content://mms-sms/conversations");

Cursor cursor = contentResolver.query(uri, projection, null, null,"_id DESC");

When the cursor is set, it with the error: FATAL EXCEPTION java.lang.NullPointerException.

This odd thing is that this works on my older versions of android, but not on the galaxy s3. SMS also seems to work fine. Any ideas? Thanks in advance!

Answer 1

Try the simplfied URI as it may be looking for a database field that's not there on the Galaxy S3.

Do as follows:

Uri uri = Uri.parse("content://mms-sms/conversations?simple=true");

and if that also does not work, try to set the projection as a "*", so the phone will basically query all fields available.
