image - Android Paint PorterDuff.Mode.CLEAR drawing black color on my view -

-

I want to implement Eraser for my painting app. I can delete the following code from 

  paint.setColor (0x00000000); Paint.setAlpha (0x00);   
 But when you start painting again, it does not paint properly, so that any ideas get rid of paint.   
 
 
 Try the code below.  
  Paint .Set Alpha (0xFF); // Transparent color paint. See xformode (new porterdaf xformode (porterdaf.mod.clear); // draw /   
 See sample fingerprint java in API demo under folder graphics.  
  setAlpha (Int a)   
 To set Helper to Color (), which specifies only the alpha value of color, its R, G, B By leaving the value unchanged.  
 See a document.  
 Edit:

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
