static initialization And multipleAPK without Jni code

edit

I use Opencv with Android Library Project SDK. I need create multiple-apk each CPU. But My code has no JNI part.(no Apllication.mk) And i can't filter CPU on AndroidManifest. How should I do?

CPU architecture (ABI)
This is based on the native libraries included in each APK (which are determined by the architectures you declare in the Application.mk file) when using the Android NDK.
