• Drawing bitmaps faster on Android canvas or OpenGL

  - by Ben Mc

  I currently have a game written using the Android canvas. It is completely 2D, and I draw bitmaps as sprites on the canvas, and it technically works, but I have a few features that I need to add that will require drawing many more bitmaps on the screen, and there will be a lot more movement. The app needs more power. What is the best way to go from this method of drawing Bitmaps on a canvas to using OpenGL so I can draw them faster?

• Non-Standard widget size for Android

  - by heorling

  I have a use-case for a vertical 1x4 home screen widget on android. The supported size is 4x1 ie horizontal. Does anyone know if the vertical version can be implemented? I realize changing screen orientation would scrunch the widget together, which I'm fine with. Even better would be if there was an equivalent to "overflow hidden" in css. Has anyone come across a way to do this?

• Looking for similar projects: Iphone/Android + Google Maps + "external" database = sightseeing map

  - by sniurkst

  Hello, sorry, it's not exactly a programming question, but I am currently in a research state and looking for similar projects, so I could analyze them: It should be application to iPhone or Android or other mobile platform, where, basically, user can access map with "places of interest" and add it's own "place of interest" (with photo and description). Kind of, community generated sightseeing map. I know it is quite simple and not a groundbreaking idea, but my google-fu is quite weak and I can't find anything like that.

• Create and display indoor map on Android

  - by Lorenzo Barbagli

  I'm developing an Android application and I would like to display an internal (indoor) map of some buildings, but I don't know where to begin: I want to create a custom kml file (how it's possible to create it? with which tool?) and display it in a fragment. I already have it working with external maps (simple GoogleMap in MapFragment), so it would be super to have the kml file placed 'over' the GoogleMap, like real indoor maps. Thanks

• Send data from Service to Widget on Android.

  - by Jose Vega

  I am writing a widget on Android 1.6 that shows the minutes that a person has used on the current month. The way I have it setup is by having a service that listens to the state of the phone and when the phone is picked up, it starts the timer and when the person hangs up, ends a timer. I would like to send this variable(long duration) over to my appWidgetProvider so I could update the edit text on it.
