MMS CONTENT SUPPLIER QUESTION (Samsung Galaxy S3)

We encounter the following failure when we try to request “content: // mms-sms / conversations /” on a Samsung Galaxy S3 (Android 4.0.4) running on a Sprint network. Our code:

Uri uri = Uri.parse("content://mms-sms/conversations/"); Log.e("IL", "CONTENT MIME " + context.getApplicationContext().getContentResolver().getType(uri)); // The next call crashes... Cursor cursor = context.getApplicationContext().getContentResolver().query(uri, null, null, null, null);

An interesting fact is that the above log returns

  CONTENT MIME vnd.android-dir/mms-sms

as was expected.

The problem can be solved using a simplified version of the request:

 Uri.parse("content://mms-sms/conversations?simple=true"); Cursor cursor = context.getApplicationContext().getContentResolver().query(uri, null, null, null, null);

Keypoint here is the URI content://mms-sms/conversations?simple=true .

This ContentProvider does not accept null projection. You must explicitly specify it with "*" so that it is passed to the SQL query:

 final String[] proj = {"*"}; Cursor cursor = context.getApplicationContext().getContentResolver().query(uri, proj, null, null, null);

I assume this is a common problem with Android.
