The one I need most is No 1, Creating a custom infowindow, I have already been able to read from SQL db and populated Google map default markers. I only need a customized infowindow to popup from the googlemap maker.I have already worked on warwound example as I stated in #1 above. What I did so far with Warwound example is attached above in #1 above as Customized Annotation2. After compilation and installation, it crashes without any log trace. My ordinary Google map with markers with default info windows are OK and running well, but once I integrate customized annotation2 above to it or run it alone, it crashes
