Is it possible to read/edit shared preferences in native code?

Question

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... is it possible to read/edit shared preferences in native code?

Answer 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.
