In Java, there is Context.getCacheDir(). It is available from C only if you have a reference to some Android object (Activity or Context), and do the dance of accessing the Java stuff: http://stackoverflow.com/questions/7595324/creating-temporary-files-in-android-with-ndk It would be possible for the Java code to set sqlite3_temp_directory, but the Android framework does not do it, and it would probably not be a good idea to require every app to do it. Android (and Chromium on Android) just use SQLITE_TEMP_STORE=3 for this reason: https://android.googlesource.com/platform/external/sqlite/+/master/dist/Android.mk https://bugs.chromium.org/p/chromium/issues/detail?id=138128 https://codereview.chromium.org/10809015 Apparently, Martin's SQLite library was compiled differently.
