codeStyleSettings.xml always modified by Android Studio

Question

Using Android Studio 1.3.2, the .idea/codeStyleSettings.xml is constantly modified to add a section for <Objective-C-extensions>...</Objective-C-extensions\>. These changes are despite no Objective-C code existing within the project. After many attempts, I have been unable to revert these changes - they keep coming back every time Android Studio is opened.

Where are these changes coming from and how can I avoid Android Studio constantly restoring the modifications?

<Objective-C-extensions>
  <option name="GENERATE_INSTANCE_VARIABLES_FOR_PROPERTIES" value="ASK" />
  <option name="RELEASE_STYLE" value="IVAR" />
  <option name="TYPE_QUALIFIERS_PLACEMENT" value="BEFORE" />

  </extensions>
</Objective-C-extensions>

Answer 1

The <Objective-C-extensions> Section is added by the Android NDK Support Plugin. Which was added in 1.3 and is activated by default.

If you have activated this plugin it adds the Section to your codeStyleSettings.xml. Otherwise it will be removed.

Answer 2

Ran into this exact problem, which hampered process since codeStyleSettings.xml was a version controlled file. Solved it (on my Windows machine if that makes a difference) with the low-tech solution of marking the file as read only. Android Studio complained about it the first time after making that change, but I prevented it from unsetting read-only and things worked fine after that.
