Hello ：
1、When I loaded GeoPackageFeatureTable，try to set a value to filed its datatype is DatatTime，will throw exception "Abort due to constraint violation" 。But use GeodatabaseFeatureTable or ShapefileFeatureTable is ok。
2、The datas of GeoPackage.gpkg file is create by arcgis desktop 10.4 and input from shpfile。
3、Can you tell me the right way of operation ，Thanks！

Running environment : com.esri.arcgisruntime:arcgis-android:100.2.1 and com.esri.arcgisruntime:arcgis-android:100.3.0 、android 7.1

Code：
`
GregorianCalendar gregorianCalendar =new GregorianCalendar();
gregorianCalendar.setTime(new Date());
feature.getAttributes().put("CREATETIME", gregorianCalendar);
...

ListenableFuture result = geotable.addFeatureAsync(feature);
result.addDoneListener(new Runnable() {
@OverRide
public void run() {
try {
result.get();
} catch (Exception es) {
Log.e(TAG, "",es );
}
}
});
