Can I gain some efficiency by declaring appropriate members "static" in Android Activity -


If any action is singleton in practice, I think that appropriate members can achieve some efficiency by declaring "stable" Are risks with zero Yes?

-

There is more than one example "single task" Or "single instance" activity, so that all new intents are expected to handle.

It means you can use a static member .

In addition, require a thread-safe static member only in a standard or one click . Let's assume that the current activity stack is A-B-C-D if the intent to arrive is for an activity of Type B, which is in "Standard" or "Single Top" mode. A new example of B will be launched (since B is not at the top of the heap), so the resulting stack will be A-B-C-D-B.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
