[android-developers] Calendar fail to launch in Cupcake 1.5
Hi, Is there anyone know why Calendar in Cupcake 1.5 fails to launch? I googled and found nothing about this issue. Is it. In addition, I got some error msg with logcat saying superclass of CalendarAppWidgetProvider was unable to resolve. However, I can't find CalendarAppWidgetProvider class from source code nor can I find it by googling the web at all. Hope someone can help. Thanks. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] ExpandableListView crash when the list starts empty
Hi, I have a problem with ExpandableListView crash. When an ExpaldableListView first starts with empty cursor (cursor without data row) and later on change a cursor with data row. There is 100% chance the ExpandableListView will crash when expand mainGroup item. I am not sure is it a bug in Android because I can't find any bug in my code. Below is the step i used to reproduce the crash (1) In onCreate, create simpleCursorTreeAdapter and make sure the data set returned is empty. (2) In onCreate, add the simpleCursorTreeAdapter to an ExpandableListView (3) when button "add" is clickked, i will do myAdapter.getCursor ().reQuery(); myAdapter.notifyDataSetChanged() (4) At this point, there will be a newly added and the only row in ExpandableListAdapter. (5) Click on the item to make the list expand. Then my program will crash. Note: It doesn't matter if there is child row under the group i clicked. it will just crash.

We found a way to reproduce it. Version: Android 1.5 Application: Browser Reproduce procedure: (1) Open Browser (2)Goto URL www.baidu.com (3) type nothing in the text field but click (with trackball) the button directly Sympton: Clicking submit button in pure CGI form based web page without typing text, there is fail rate that Browser will fail to respond to track ball click.

[android-developers] pixel to dpi and scaling question
Hi, I was reading multiple screen support page on SDK doc for solving a pixel to dpi scaling problem in my app. In the doc, it says "// Convert the dips to pixels final float scale = getContext().getResources().getDisplayMetrics().density; mGestureThreshold = (int) (GESTURE_THRESHOLD_DIP * scale + 0.5f);" My question is why we have to add 0.5f at the end? It indeed works great on high density screen but failed to match the result on medium density screen. For medium density screen, I have to remove the +0.5f. In addition. according to the doc, px - dpi conversion works like px = dpi x (density/160) and there is no mentioning of adding additional 0.5 at the end. Does anybody know why and how it works?
