PaletteGetter is a library that attempts to reliably obtain the color scheme of any app from just the package or component name.
For testing and experimentation purposes, a sample apk can be downloaded here.
The Gradle dependency is available through jCenter, which is used by default in Android Studio. To add the module to your project, copy this line into the dependencies section of your build.gradle file.
Getting a Single Color
From Package Name
To get a color from the package name of an app, use the method below.
Integer color = PaletteGetter.get(context, packageName);
If the package name isn’t valid, the method will return null.
From Component Name
Getting a color from a component name is sometimes more accurate than a package name because it specifies which part of an app you want the color from. To get the color from a component name, use the method below.
Integer color = PaletteGetter.get(context, componentName);
Getting Multiple Colors
To get all the colors in an application, use the method below. This will return a
List of all the known colors in that application, and may contain a few duplicates. If the package name is invalid, it will return an empty
List<Integer> colors = PaletteGetter.getPalette(context, packageName);
