Expert tip

When installing an APK, it automatically extracts the libraries of the right arch type and has them available for System.loadLibrary. But, if you're trying to load a non-standard library, the installer won't know your app has 32bit native code.


This is a sub-class of the LinkageError class and indicates that the JVM cannot find an appropriate native-language definition of a method declared as native. Compile a 64-bit version of your .dylib file.
