获取其他应用程序图标URI？

问题描述

我有一个Android appwidget这表明它的其他应用程序的图标。

I have an Android appwidget which shows icons of other applications on it.

我得到appInfo.loadIcon其他应用程序的图标，然后我将它设置为与setImageViewBitmap小部件。

I get the other applications icons with appInfo.loadIcon and then I set it to the widgets with setImageViewBitmap.

问题是，如果我有在部件上有太多图标，我碰到一个失败粘结剂交易的错误。据我所知，它的大小限制及本解决方案它使用的图像，而不是URI位图本身。

The problem is that if I have too many icons on the widget, I get "FAILED BINDER TRANSACTION" error. I understand that it's from a size limit and the solution it to use the image uri instead of the bitmap itself.

有一个可访问的URI到其他应用程序的图标？

Is there an accessible URI to other applications' icons?

感谢。

Try android.resource://[package]/[res type]/[res name], where [res type] in your case would be drawable. The package and name would have to come from the ResolveInfo or wherever you are getting your data.
