I think the projection is causing the problem. Here's a copy of my
Projection-object:
projection PixelConverter (id=830060753840)
+ mInverse Matrix (id=830060753992)
+ mMap Map (id=830060693368)
biller MapBiller (id=830060694872)
centerPixelX 2610768
centerPixelY 1626375
completeTilesInViewport 0
displayHeight 0
displayWidth 0
earliestTileNeededTime 0
halfHeight 0
halfWidth 0
isViewportAllNew false
lastPaintStartTime 0
layerServices Vector (id=830060693664)
mapService MapService (id=830060696344)
mapState MapState (id=830060726304)
pixelMapper null
running true
tileOverlayRenderer AndroidTileOverlayRenderer
(id=830060769480)
tiles null
topLeftTile Tile (id=830060726360)
xTiles 0
yTiles 0
+ mMatrix Matrix (id=830060753976)
+ mTempFloats float[2] (id=830060754008)
+ mTempPoint Point (id=830060754320)
If you need any further information please say so.
