我有一个类在我的android项目的同一个java文件中声明，我的代码由于某种原因不能识别它？当我在模拟器中运行时，我在运行时遇到NoClassDefFoundError。NoClassDefFoundError类已在同一个java文件中声明
我收到以下错误，当我尝试运行我在模拟器Android应用程序：

这里是我的代码：
AsyncOverlay(LoggerMap loggermap, Handler handler)
{
mLoggerMap = loggermap;
mHandler = handler;
mWidth = 1;
mHeight = 1;
mPaint = new Paint();
mActiveZoomLevel = -1;
mActiveBitmap = Bitmap.createBitmap(mWidth, mHeight, Bitmap.Config.ARGB_8888);
mActiveTopLeft = new GeoPoint(0, 0);
mActivePointTopLeft = new Point();
mCalculationBitmap = Bitmap.createBitmap(mWidth, mHeight, Bitmap.Config.ARGB_8888);
mOsmOverlay = new SegmentOsmOverlay(mLoggerMap.getActivity(), mLoggerMap, this);
mMapQuestOverlay = new SegmentMapQuestOverlay(this);
}
这里是我的类：
static class SegmentOsmOverlay extends org.osmdroid.views.overlay.Overlay {
AsyncOverlay mSegmentOverlay;
LoggerMap mLoggerMap;
public SegmentOsmOverlay(Context ctx, LoggerMap map, AsyncOverlay segmentOverlay)
{
super(ctx);
mLoggerMap = map;
mSegmentOverlay = segmentOverlay;
}
public AsyncOverlay getSegmentOverlay()
{
return mSegmentOverlay;
}
@Override
public boolean onSingleTapUp(MotionEvent e, org.osmdroid.views.MapView openStreetMapView)
{
int x = (int) e.getX();
int y = (int) e.getY();
GeoPoint tappedGeoPoint = mLoggerMap.fromPixels(x, y);
return mSegmentOverlay.commonOnTap(tappedGeoPoint);
}
@Override
protected void draw(Canvas canvas, org.osmdroid.views.MapView view, boolean shadow)
{
if (!shadow)
{
mSegmentOverlay.draw(canvas);
}
}
}
有什么建议吗？
Java文件的名称是什么？ – hmatar
.class文件是否在目录结构的适当位置？ （对应于它的'package'。） –
什么是类的访问修饰符？ – Smit
