Google IntelliJ java style: changing 2-space indentation to 4-space indentation

Question

I have installed google-java-format plugin for IntelliJ and I have enabled the plugin. When I format the code, my java code gets indented by 2 spaces. How do i change the google java formatter plugin setting to change to 4 spaces?

Answer 1

First I disabled the IntelliJ google-java-format plugin.Downloaded IntelliJ-java-google-style.xml from here and modified indent size property as below. After importing this style in IntelliJ, I am able to indent to 4 spaces. To import the code style XML, please refer to this link

  <codeStyleSettings language="CSS">
    <indentOptions>
      <option name="INDENT_SIZE" value="4" />
      <option name="CONTINUATION_INDENT_SIZE" value="4" />
      <option name="TAB_SIZE" value="4" />
    </indentOptions>
  </codeStyleSettings>

Answer 2

I was able to change to 4-space indentations by selecting the Android Open Source Project (AOSP) style in the google-java-format plugin settings:

It looks like the only difference between the two styles is that AOSP doubles the spacing to 4 instead of 2: https://github.com/google/google-java-format/blob/master/core/src/main/java/com/google/googlejavaformat/java/JavaFormatterOptions.java#L37
