android - Unbinding drawables from view on onDestroy() -

-

I've read a lot about memory leaks in the last few days, and came in some interesting stuff. I saw a basic Android bitmap memory leak question (since 2011) and I was thinking that this is still the case. If I am using scenes that contain bitmaps in my activity (image view, text view ...), do I need to break my own designs to destroy the activity? Is it only in some cases or always?

It is no longer required as 4.0 because callback is now a WeakReference .

: Public Final Zero Set Callback (Callback CB) {mCallback = cb; }

and: 

  public final zero set callback (callback CB) {mCallback = new WeakReference & lt; Callback & gt; (CB); }

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
