NullPointerException in BaseModelProvider.setMatcher(Uri)

[kasim1011]

I sometime get the NullPointerException in BaseModelProvider's setMatcher method when I call select() method on model. I don't what's the reason behind it.

Here's the uses:

StandardStandard standardStandard = new StandardStandard(mActivity, mActivity.user());
/// NullPointerException
List<ODataRow> standardStandardDataRows = standardStandard.select();

Here's the log:

Here's the another uses:

AbsentReason absentReason = new AbsentReason(mActivity, mActivity.user());
/// NullPointerException
List<ODataRow> absentReasonDataRows = absentReason.select();

Here's its log:

I want to know what's the possible reasons behind happening this.

@kasim1011 Due to null BASE_PROVIDER in OModel constant BaseModelProvider not able to find proper authority string mapped with your model class. Fix done in f691971 commit.
