Owner:Svetosla...@android.com comment 6 by dfuern...@gmail.com, Jun 7, 2012 If you add another app (see attachment for example) to your emulator supporting ShareIntents of type text/plain and accepting Intent.ACTION_SEND, the ShareProvider will work. It then also displays the already mentioned Messaging App. This however should be considered a workaround. Pva-sharetarget.zip

Iteration and recursion in python

In one case, recursive operations are required, but the number of recursion times is very large, with more than 10 thousand. Let's not talk about the recursion for more than 10 thousand times. The original test code is java, and the jdk and compilation environment are not installed. Use python to check the original java code first: copy the public class UpCount {private long calc (int depth) {if (depth = 0) return 1; long cc =

Python indentation issues

As the number of arguments is uncertain, we first think that we can put a,b,c ...
