Native application crashes on Android L

Question

I have a native application that always worked on Android KitKat with both Dalivik and ART runtimes, but it now crashes on Android L with the following trace:

E/art(12810): dlopen("/data/app-lib/com.mylib.example", RTLD_LAZY) failed: dlopen failed: cannot locate symbol "issetugid" referenced by "mylib.so"...
D/AndroidRuntime(12810): Shutting down VM
E/AndroidRuntime(12810): FATAL EXCEPTION: main
E/AndroidRuntime(12810): Process: com.mylib.example, PID: 12810
E/AndroidRuntime(12810): java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "issetugid" referenced by "mylib.so"...
E/AndroidRuntime(12810):    at java.lang.Runtime.loadLibrary(Runtime.java:364)
E/AndroidRuntime(12810):    at java.lang.System.loadLibrary(System.java:610)

Is ART runtime in Android L different from KitKat? There is no new NDK available yet, therefore, how to avoid this crash, because it seems that the function issetugid is no longer supported.

Answer 1

The issue has been fixed in the final Android 5.0 release. There is no need to re-compile existing binaries.

However, if the native lib is compiled with target android-21, it fails on previous Android versions (< 5.0)
