i am developing an android app using arcgis sdk and developing my map for the app using arc map 10.2. i am using image from goggle earth as my base map and added some layers to it working fine but it was using unknown coordinate system and the coordinates were not correct..so when i assign the correct coordinates using x,y and check it out the features and the base map are not on the same coordinate and its not displaying the features.so i deleted the existing features and tried to draw new ones but it says feature can not be created.te geometry is invalid. so i tried to use geographical coordinate system and assigned the coordinates,but since the base-map is not a layer or a shape file i cannot change it.so either the feature or the base-map is displayed
.please what should i do
