arcgis for android

I arcserver published map services, have also been slicing. Why do I use static methods ArcGISTitledMapServiceLayer can not display the map reading map, but with ArcGISDynamicMapServiceLayer can read dynamic maps, solve ah?
main.xml code as follows:
read Dynamic Map: ---------- can achieve -

xmlns: android = "http://schemas.android.com/apk/res/android"
android: id = "@ + id / map" android: layout_width = "fill_parent"
android: layout_height = "fill_parent"
initExtent = "103.65260352265571 30.601990757646366 105.81798514963432 33.15940564749478">

read static slice ------------ not realize

xmlns: android = "http://schemas.android.com/apk/res/android"
android: id = "@ + id / map" android: layout_width = "fill_parent"
android: layout_height = "fill_parent"
initExtent = "103.65260352265571 30.601990757646366 105.81798514963432 33.15940564749478">
