I also have spent a lot of time trying to figure this out.  I haven't tried your solution yet but it looks like it should work.  Exactly what I was looking for. (working on the Android side through) If someone from ESRI is looking at this a sample with a date query would be helpful   ... View more

With a cursory look it seems like the code should work.  Have you debugged and caught the table exception if there is one?  It could be that the point is outside of the GDB extent.  When you created the offline .geodatabase an extent was needed. Instead of creating the point from a static x-y coordinate I would use a map tap event to get the x-y like so public boolean onSingleTap(final MotionEvent e) { mMapView.toMapPoint(new Point(e.getX(), e.getY())) } Hope that helps. ...

I have tried that.  My code supplied above is very simplified.  I had a graphic added to a graphics layer then I pass that graphic to another intent by graphicLayer.getGraphic(UID).  I have yet to be successful in this. I have however solved the ultimate issue of setting the spatial Reference of my FeatureSet which can be accomplished by simply using the "setSpatialReference(SR)" method.  But the graphic and Spatial Reference issue is still a mystery to me. ...

In case anyone is having this issue or has it in the future. I Revisited this problem after some time and fixed it. It was due to architecture issues, and was solved by creating a global variable of a Geodatabase and always using that variable for database operations.  Previously I was creating new instances of a geodatabase and using that for inserts. So here is what I do now: static Geodatabase localGDB; //declare global variable in main activity localGDB = new Geodatabase("path/to/local/my.geodatabase"); //instantiate geodatabase in on create or elsewhere MyActivityWithGlobalVar.localGDB //reference localGDB variable in other activities in this way when doing anything to it ...

I followed your advice and I was able to select the features via queryFeatures with a simple where "1=1" query.  After that I was also able to select features via a spatial query.  After much digging I have found the source of the problem is but still don't know the cause or a solution.  It seems that there is a disconnect between my global variable that is a feature layer when it is added to the map view and when I try to use it inside of my MyTouchListener class.  Or it has to do with the declaration of the call back as a global variable.  However, both of these are exactly how the Select Features sample has them declared. 1. The only way I can get the FeatureLayer.SelectFeatures(QueryParamaters,...) to work is to add that layer to the mapview at time of selectFeatures.  This leads to duplicate layers.  2.  On the other hand I can use the global featureLayer when using the method described above using queryfeatures on the geodatabaseFeature table then passing the oids captured in the callback to FeatureLayer.selectFeatures(long[] oids,..)   However using this method in a dynamic way for any/all layers possibly present in a map is proving logically difficult.  3.  Tried using and this does not work either.  mmapview.getLayers() does not refer back to the actual map layers after I cast them to FeatureLayer. Layer[] allLayers = mMapView.getLayers(); for (Layer layer : allLayers) {      try{           FeatureLayer xFeatureLayer = (FeatureLayer) layer;           QueryParameters q = new QueryParameters();           q.setGeometry(g.getGeometry()) //g being a qualifying graphic           q.setSpatialRelationship(SpatialRelationship.INTERSECTS)           //other qualifying query paramaters...           //....           xFeatureLayer.selectFeatures(q, SelectionMode.NEW, callback);           }catch (Exception ee) {                ee.printStackTrace();           }      } So I still don't have a way to select features without adding new Feature layers in at time of query OR capture all Featurelayers added to the map as global variables, then do a combination of queryFeatures and SelectFeatures(long[] oids, ...).  Neither of these seem like the intended way of handling this. Any thoughts?  Your continued thoughts/help is much appreciated.  Thanks! ... View more

Thank you very much for your reply.  I have noticed that my variable g (my graphic) does not have a spatial reference.  It is null.  I tried several things but can not seem to rectify this by any means. I am now trying to figure out how to give it a spatial reference.  It is derived from a graphicsLayer which has a spatial reference.  I'm not sure I am understanding the relationship between the graphic, graphicLayer and Envelope. Here is a better sample of my code.  Should a graphic inherit a spatial relationship from a graphics layer?  I don't see a way to create a graphic with a spatial relationship or a way to set one.  Do I need to project it (this would seem overly complex)? Thank you very much for your help. GraphicsLayer gLayerSelect = new GraphicsLayer();  //Global Var gLayerSelect = new GraphicsLayer(mMapView.getSpatialReference(),null,RenderingMode.DYNAMIC); //Defined in on Create mMapView.addLayer(gLayerSelect);//added in on Create private class MyTouchListener extends MapOnTouchListener {      Graphic g;      Point p0 = null;      int uid = -1;      SimpleFillSymbol sfs; public MyTouchListener(Context context, MapView view) {      super(context, view);      sfs = new SimpleFillSymbol(Color.BLACK);      sfs.setOutline(new SimpleLineSymbol(Color.RED, 2));      sfs.setAlpha(100); } public boolean onDragPointerMove(MotionEvent from, MotionEvent to) {      if (uid == -1) { // first time           //Geometry xGeometry = mMapView.toMapPoint(new Point(from.getX(), to.getY()));           //g = new Graphic(xGeometry, sfs);           g = new Graphic(null, sfs);//original           p0 = mMapView.toMapPoint(from.getX(), from.getY());           uid = gLayerSelect.addGraphic(g);      } else {           Point p2 = mMapView.toMapPoint(new Point(to.getX(), to.getY()));           Envelope envelope = new Envelope();           envelope.merge(p0);           envelope.merge(p2);           gLayerSelect.updateGraphic(uid, envelope);      }      return true; } public boolean onDragPointerUp(MotionEvent from, MotionEvent to) {      if (uid != -1) {           g = gLayerSelect.getGraphic(uid);           if (g!= null && g.getGeometry() != null) {                fLayer.clearSelection();                QueryParameters q = new QueryParameters();                q.setWhere("1=1");                q.setOutSpatialReference(mMapView.getSpatialReference());                q.setReturnGeometry(true);                q.setInSpatialReference(mMapView.getSpatialReference());                q.setGeometry(g.getGeometry());                q.setSpatialRelationship(SpatialRelationship.INTERSECTS);                fLayer.selectFeatures(q, SelectionMode.NEW, callback);                               if (g.getSpatialReference() == mMapView.getSpatialReference()){                     String X = "";                }           }           gLayerSelect.removeAll();      }      p0 = null;      uid = -1;      return true; } ...
