error loading en aac decoder libary. With target 22 work fine, the problem
is with target 26.

java.lang.UnsatisfiedLinkError: dlopen failed:
/data/app/com.cqsoluciones.radio.ironmaxradio-2/lib/arm/libaacdecoder.so:

This change has been covered here:
https://android-developers.googleblog.com/2016/06/android-changes-for-ndk-developers.html

You'll most likely have to rebuild the problematic library with some
changes, see e.g.

NDK libraries that you package with your app are now (as of Oreo 8.0.0, API
26) being installed on a file system path that has a random element. This
random path changes each time the app is installed. The random path is a
new security measure, and makes it very difficult for other apps to find
and make use of your libraries. Like you, I also make dlopen calls to load
NDK libraries (that I package) in an app I am developing. I had to add a
call to MyApp.getContext().getApplicationInfo().nativeLibraryDir; (on the
Java side of the JNI) to get the path with the random string in it. Use
that with dlopen, and your library will be found.

There may be a way to get this path directly in the NDK API. Since the app
I am working on make heavy use of the JNI in both directions, it was easier
to call the Java API to get it.

Your old dlopen method will probably work on Android 7 (API 24-25).
