Is It Possible To Read/edit Shared Preferences In Native Code?

I have an Android app that includes a C library using NDK to execute some some code. Within the C library I would like to update the applications shared preferences. My question...

Solution 1:

You can do anything you want in native code. It's just cumbersome - you need the JNIEnv object to first find the class ID, then the method ID, if you have any non-primitive types, you need to create those too. But then you just call the method, and you're done.

JNI Docs - look for FindClass, GetMethodId, CallVoidMethod, etc.
