Question

I want to use OpenSL` ES only when available i.e. if Android version >= 2.3

Currently I have in Android.mk

LOCAL_LDLIBS    += -lOpenSLES

But this won’t work if Android version < 2.3

Can I somehow load Open SL library dynamically only if Android version >= 2.3, maybe using System.loadLibrary ?

Answer 1

Use Build.VERSION to check the API version before you load the library and if it’s lower than API 9, don’t load it.

Example:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
    System.loadLibrary("xyz");
}

OR if you want to have one native library, loading OpenSL ES dynamically, you can use dlopen. You can find an example on stackoverflow: https://stackoverflow.com/a/1142169/1145705
