Can anybody tell me the reason for failed binder transaction error? I can see this error message in logcat. I am getting this error while trying to put an bitmap dynamically in a widget...

推荐答案

这是造成的，因为所有的改变RemoteViews被序列（如SETINT和setImageViewBitmap）。位图也被序列化到内部包。不幸的是这种捆绑有一个非常小的大小限制。

This is caused because all the changes to the RemoteViews are serialised (e.g. setInt and setImageViewBitmap ). The bitmaps are also serialised into an internal bundle. Unfortunately this bundle has a very small size limit.

您可以通过缩小图像大小这种方式解决这个问题：

You can solve it by scaling down the image size this way:

public static Bitmap scaleDownBitmap(Bitmap photo, int newHeight, Context context) { final float densityMultiplier = context.getResources().getDisplayMetrics().density; int h= (int) (newHeight*densityMultiplier); int w= (int) (h * photo.getWidth()/((double) photo.getHeight())); photo=Bitmap.createScaledBitmap(photo, w, h, true); return photo; }

选择newHeight足够小（〜100每平方应采取在屏幕上），并用它为你的小工具，你的问题就解决了​​：）

Choose newHeight to be small enough (~100 for every square it should take on the screen) and use it for your widget, and your problem will be solved :)
