[android-developers] use big size Bitmap in AppWidget
hi all: I am attempting to create an android Widget application which display more than 10 images in ListView. The image size depends on screen resolution, so the image might be 300*300 pixel on some high resolution devices. When scrolling the listview Widget, the widget looks laggy and choppy. However, this laggy problem only happens on some high resolution device. I looked into android source code, and find out that there is a cache in RemoteViewsAdapter whose size is fixed to 2MB. 2MB is enough in most device, but not in high resolution devices. Is there anyone see this problem as well? Any help would be appreciated. thanks -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Update single item in Collection in an AppWidget
It does not work. But the latest android 4.1 emulator, I don't see this problem any more. So I think this is an android bug under 4.1 version. But still want to know here that is it possible in application side to fix this problem?

If i use the AppWidgetManager.notifyAppWidgetViewDataChanged the whole collection is redrawn and the scroll position resets. Does someone know another possibility to update a single item?

[android-developers] IndexOutofBoundsException thrown from getViewAt() in RemoteViewFactory
I am attempting to create a widget for android 4.0 phone. But the widget might crash after user clicks the clear data button in application's setting view. I looked into logcat, it saysIndexOutofBoundsException in getViewat() method. This is super weird in my eyes, since I put log in both getCount() and getViewat() methods. Firstly, getCount() methods return 1, but the consequence getViewat() is still trying to get view at position 1 and 2. Is there anyone see this problem before? any thoughts would be appreciated, thanks -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] IndexOutofBoundsException thrown from getViewAt() in RemoteViewFactory
I didn't ask for getViewAt(index=1), this method is called by android framework(I think it's called by RemoteViewsAdater). I can not figure out the reason RemoteViewsAdatper is calling getViewAt(index=1) after it called getCount() which returns 1. I suspect that this is an android bug, since I didn't do anything wrong according the docs.

If getCount() returns 1, you shouldn't ask for getViewAt(index) where index = 1. It's your responsibility to make sure you do not exceed getCount() limits (at least usually). -- H -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] webview can not display twitter page
I am developing an app with twitter sharing feature. User can share information via twitter. After user click the twitter image in app view, a webView is brought up with a twitter share url. But the webview is always a blank page. Only twitter url does not work, facebook url works very well. It looks like webview does not support redirecting, right? PS: I've set the javascript enable of webview, still do not work for twitter share url. -- You received this message because you are subscribed to the Google Groups Android Developers group.
