transparent is not part of the SVG specification, although many UAs such as Firefox do support it anyway. The SVG way would be to set the stroke to none, or alternatively set the stroke-opacity to 0. You also don’t set any value for fill on the <rect> element and the default is black. For a … Read more
Use this instead: convert \ input.png \ -background none \ -gravity center \ -extent 100×100 \ output.png Note well: The order of the parameters is significant! (To convince yourself, just put -background none at the end of the parameters instead of the start…) Updated: Thanks to @jesmith who noticed that the commandline I originally provided … Read more
A Context is a handle to the system; it provides services like resolving resources, obtaining access to databases and preferences, and so on. It is an “interface” that allows access to application specific resources and class and information about application environment. Your activities and services also extend Context to they inherit all those methods to … Read more
Android doesn’t provide it, you can implement a method to determine this. Here a method to do that: public boolean isColorDark(int color){ double darkness = 1-(0.299*Color.red(color) + 0.587*Color.green(color) + 0.114*Color.blue(color))/255; if(darkness<0.5){ return false; // It’s a light color }else{ return true; // It’s a dark color } }
When should the handler be called? Call it after you are done your job. Your code should not do complex operations. The app is in the background and the user does not see what’s changed. You can just set a “flag” that data is updated and do complex operations after the user launched the app. … Read more

I have seen this behavior, too. After trying a lot I discovered two things, which could help. But I am still uncertain how this may influence the reviewing process. If you use one of the backgrounding features, the app will be launched by iOS in background again once it was quit (by the system). This … Read more
override func viewDidLoad() { super.viewDidLoad() self.view.backgroundColor = UIColor(patternImage: UIImage(named: “background.png”)) }
Here is a really nice explanation: Put your “back.png” image on “drawable” folder. Then create a drawable “backrepeat.xml” like that: <?xml version=”1.0″ encoding=”utf-8″?> <bitmap xmlns:android=”http://schemas.android.com/apk/res/android” android:src=”https://stackoverflow.com/questions/1700099/@drawable/back” android:tileMode=”repeat” /> In your layout, add android:background=”@drawable/backrepeat”: <?xml version=”1.0″ encoding=”utf-8″?> <LinearLayout android:id=”@+id/MainLayout” xmlns:android=”http://schemas.android.com/apk/res/android” android:layout_width=”fill_parent” android:layout_height=”fill_parent” android:orientation=”vertical” android:background=”@drawable/backrepeat”> </LinearLayout> As is the case with many Android good practices/handy tricks, it … Read more
