CANNOT LINK EXECUTABLE "app_process": cannot locate symbol

[micjan]

Hi

I couldn't find any references to a similar problem elsewhere.

I've upgraded my Android TV box recently (to Android 7 API 24), and now whatever app I build in the Android Studio I get errors similar to below when I run it:

11-27 16:01:02.646 4859-4859/? A/libc: CANNOT LINK EXECUTABLE "app_process": cannot locate symbol "_ZN7android16DrmManagerClient19finalizeDecryptUnitERNS_2spINS_13DecryptHandleEEEi" referenced by "/system/lib64/libstagefright.so"...

The actual symbol in 'cannot locate symbol' may vary, for instance another time I got a missing symbol from libdrmframework.so.

What may be causing this? Is there something I can try?

Thanks
