Hello every one..I'm doing a project and on that i decide to draw a path on the map by giving relevent coordinates and after that it draws on the map. Up to now i did that part by using your help as i very new to ArcGIS runtime.. Now i want to identify water paths, main roads that cross the drawn path.Here i want to identify all the road that cross the drawn polyline and put a marker on the crossing places at once.Can i do that on the ArcGIS runtime sdk with android or is there another way to detect? ...

Hello every one. I'm new to ArcGIS and I want to add path(polyline) on the map after  giving coordinates where to draw. I follow the guide Display Information -> add graphics and text. But not displaying the path and even not occur any error.

I'm new to ArcGIS runtime sdk and i want to add simple markers on the map.. So i tried the guid-> Display Information -> add graphics and text codes and before that i made the map by referring guid -> Tutorials -> Use ArcGIS base map. After run this on my mobile device i got the error as follow. Error is on the  Geometry normalized = GeometryEngine.normalizeCentralMeridian(mMapView.getExtent(), mMapView.getSpatialReference()); line. 03-10 10:20:38.475    4133-4133/com.example.t_buddhika.gis2 E/AndroidRuntime﹕ FATAL EXCEPTION: main     java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.t_buddhika.gis2/com.example.t_buddhika.gis2.gis2}: java.lang.IllegalArgumentException: Input geometry can't be null.             at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2186)             at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2236)             at android.app.ActivityThread.access$600(ActivityThread.java:145)             at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1238)             at android.os.Handler.dispatchMessage(Handler.java:99)             at android.os.Looper.loop(Looper.java:137)             at android.app.ActivityThread.main(ActivityThread.java:5099)             at java.lang.reflect.Method.invokeNative(Native Method)             at java.lang.reflect.Method.invoke(Method.java:511)             at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:803)             at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:570)             at dalvik.system.NativeStart.main(Native Method)      Caused by: java.lang.IllegalArgumentException: Input geometry can't be null.
