“Resources“ is a public class in Android which is used to store static content such as strings, colors, styles, bitmap and more.
NOTE: Static content are the files that don't change based on user input.
This is how “Resources” is organized in Android Studio.

Now I will explain some of directories in “Resources” Class one by one but first I want to tell you that when Android application is compiled, a R class gets generated, which contains resource IDs for all the resource available in your res/ directory and we will use this R class to access or file in resource using sub-directory.


  • Image file like .png, .jpg, .gif, or XML file that are compiled into bitmaps, Layer List, State List, Level List etc. are stored on this file.
  • You can get your drawable by using getDrawable(int) method in JAVA Class and access it from the R.drawable.filename class so to get 2techup.xml file from Drawable we can use getDrawable(R.drawable.2techup);


  • It is used to store XML file that define user interface layout.
  • You can access your layout in JAVA Class from the R.layout.filename class


It is used to store colors, strings, styles etc.

Some of files you can create in res/values directory

  • We can use this for storing color values.
  • To get color from colors.xml file we can use getResources().getColor(R.color.idname); method.
This is how you can store color’s in this file

<?xml version="1.0" encoding="utf-8"?>
<item name="green" type="color">#FF99CC00</item>
<item name="blue" type="color">#FF33B5E5</item>
<item name="purple" type="color">#FFAA66CC</item>
<integer-array name="androidcolors">


  • This can be used for storing string or string array.
  • To get String from strings.xml file we can use getString(R.array.string_name); method.
  • To get String array we can use getResources().getStringArray(R.array.string_array_name); method
This is how you can store Strings or String Array in strings.xml file

<?xml version="1.0" encoding="utf-8"?>
<string name="text_1">text_string_1</string>
<string name="text_2">text_string_2</string>
<string-array name="text_array">
