File Operations in Android NDK

Issue

I am using the Android NDK to make an application primarily in C for performance reasons, but it appears that file operations such as fopen do not work correctly in Android. Whenever I try to use these functions, the application crashes.

How do I create/write to a file with the Android NDK?

Solution

Other answers are correct. You can open a file through the NDK using FILE and fopen, but don't forget to place a permission for it.

In the Android manifest place:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
